I can do :%s/<search_string>/<replace_string>/g for replacing a string across a file, or :s/<search_string>/<replace_string>/ to replace in current line.
How can I select and replace words from selective lines in vim?
Example: replace text from lines 6-10, 14-18 but not from 11-13.
Replace All:
:%s/foo/bar/g
Find each occurrence of 'foo' (in all lines), and replace it with 'bar'.
For specific lines:
:6,10s/foo/bar/g
Change each 'foo' to 'bar' for all lines from line 6 to line 10 inclusive.
The :&& command repeats the last substitution with the same flags. You can supply the additional range(s) to it (and concatenate as many as you like):
:6,10s/<search_string>/<replace_string>/g | 14,18&&
If you have many ranges though, I'd rather use a loop:
:for range in split('6,10 14,18')| exe range 's/<search_string>/<replace_string>/g' | endfor
As a side note, instead of having to type in the line numbers, just highlight the lines where you want to find/replace in one of the visual modes:
VISUAL mode (V)
VISUAL BLOCK mode (Ctrl+V)
VISUAL LINE mode (Shift+V, works best in your case)
Once you selected the lines to replace, type your command:
:s/<search_string>/<replace_string>/g
You'll note that the range '<,'> will be inserted automatically for you:
:'<,'>s/<search_string>/<replace_string>/g
Here '< simply means first highlighted line, and '> means last highlighted line.
Note that the behaviour might be unexpected when in NORMAL mode: '< and '> point to the start and end of the last highlight done in one of the VISUAL modes. Instead, in NORMAL mode, the special line number . can be used, which simply means current line. Hence, you can find/replace only on the current line like this:
:.s/<search_string>/<replace_string>/g
Another thing to note is that inserting a second : between the range and the find/replace command does no harm, in other words, these commands will still work:
:'<,'>:s/<search_string>/<replace_string>/g
:.:s/<search_string>/<replace_string>/g
Search and replace
:%s/search\|search2\|search3/replace/gci
g => global search
c => Ask for confirmation first
i => Case insensitive
If you want direct replacement without confirmation, use below command
:%s/search/replace/g
If you want confirmation for each replace then run the below command
:%s/search/replace/gc
Ask for confirmation first, here search will be case insensitive.
:%s/search/replace/gci
You can do it with two find/replace sequences
:6,10s/<search_string>/<replace_string>/g
:14,18s/<search_string>/<replace_string>/g
The second time all you need to adjust is the range so instead of typing it all out, I would recall the last command and edit just the range
In vim if you are confused which all lines will be affected, Use below
:%s/foo/bar/gc
Change each 'foo' to 'bar', but ask for confirmation first.
Press 'y' for yes and 'n' for no. Dont forget to save after that
:wq
VI search and replace command examples
Let us say you would like to find a word called “foo” and replace with “bar”.
First hit [Esc] key
Type : (colon) followed by %s/foo/bar/ and hit [Enter] key
:%s/foo/bar/
We don't need to bother entering the current line number.
If you would like to change each foo to bar for current line (.) and the two next lines (+2), simply do:
:.,+2s/foo/bar/g
If you want to confirm before changes are made, replace g with gc:
:.,+2s/foo/bar/gc
To answer this question:
:40,50s/foo/bar/g
replace foo with bar in these lines between the 40th line and the 50th line(inclusive), when execute this command you can currently in any line.
:50,40s/foo/bar/g
also works, vim will ask you for comfirm and then do the replacement for you as if you have input the first command.
:,50s/foo/bar/g
replace foo with bar in these lines between the line you are currently in and the 50th line(inclusive). (if you are in a line AFTER the 50th line vim will ask for confirm again)
To clearity the difference between vim and the vrapper plugin of Eclipse:
Note that in varpper
:,50s/foo/bar/g command will NOT work.
:50,40s/foo/bar/g will work without asking for comfirmation.
(For Vrapper Version 0.74.0 or older).
Specifying the range through visual selection is ok but when there are very
simple operations over just a couple of lines that can be selected by an
operator the best would be to apply these commands as operators.
This sadly can't be done through standards vim commands. You could do a sort
of workaround using the ! (filter) operator and any text object. For
example, to apply the operation to a paragraph, you can do:
!ip
This has to be read as "Apply the operator ! inside a paragraph". The filter
operator starts command mode and automatically insert the range of lines
followed by a literal "!" that you can delete just after.
If you apply this, to the following paragraph:
1
2 Repellendus qui velit vel ullam!
3 ipsam sint modi! velit ipsam sint
4 modi! Debitis dolorum distinctio
5 mollitia vel ullam! Repellendus qui
6 Debitis dolorum distinctio mollitia
7 vel ullam! ipsam
8
9 More text around here
The result after pressing "!ap" would be like:
:.,.+5
As the '.' (point) means the current line, the range between the current
line and the 5 lines after will be used for the operation. Now you can add
the substitute command the same way as previously.
The bad part is that this is not easier that selecting the text for latter
applying the operator. The good part is that this can repeat the insertion
of the range for other similar text ranges (in this case, paragraphs) with
sightly different size. I.e., if you later want to select the range bigger
paragraph the '.' will to it right.
Also, if you like the idea of using semantic text objects to select the
range of operation, you can check my plugin
EXtend.vim that can do the same
but in an easier manner.

Objective
Yank a line and use it to overwrite some of the lines following it.
Assumption
It is preferable in this case to manually select the lines to apply the substitution to. In other words, automated find and replace is not desired.
Analogy
Think of this process as creating a “stamp” from a line of text and going through a list of items—each item being a line of text following the “stamp” line—and deciding whether that line should be overridden using the contents of the “stamp” or not (in the former case, replacing the line with the “stamp”, of course).
This last step of triggering the replacement of the line under the cursor with the contents of the stamp, should be as easy as possible; preferably, as easy as pressing . (repeat last change) or ## (execute the contents of macro register #).
Issue
The straightforward workflow is, of course, as follows.
Position the cursor on the line to be copied (using movement commands).
Enter line-wise Visual mode (via the V command).
Copy selected text (using the y command).
Manually position the cursor onto the line to be replaced (using movement commands).
Enter Visual mode again to select the text to be replaced (using the V command).
Paste over the selection (using the p command).
However, this approach does not work when the replacement has to be done multiple times. Specifically, replacing the text on step 6 overrides the (unnamed) register containing the line initially copied and intended to be used as a “stamp”.
What I have tried
I have tried using "_y to either yank or delete into the _ register, avoiding the loss of the contents of the stamp, but I am looking for something that ends up being quick and comfortable to type as I manually go through the list and apply replacements where I see fit.
What I would prefer not to use
I would rather not use macros or “remaps” for this, if I can help it.
Illustrative sample file
See the sample starting file below, followed by the desired final stage, for further clarity.
Sample file, starting condition
At this stage, I select the blueberry and make it my “stamp”.
blueberry
apple
banana
coconut
apple
banana
coconut
apple
banana
coconut
Sample file, desired final state
After having moved through the list, I have applied some replacements, “stamping” over some lines, making them the same as the “stamp” blueberry line.
blueberry
apple
banana
blueberry
apple
banana
coconut
apple
banana
blueberry
To make your workflow work as expected, you need to paste from the previous yank register "0, rather than the default register.
So use Vy (or yy, which is the same) to yank the first line as before, then position the cursor over the line you want to replace, and do
V"0p
this replaces the current line with the previously yanked text, but doesn't overwrite the yanked text. I hope I understood you correctly!
EDIT 1: repeating using a macro
I was surprised that this operation isn't repeatable using ., but this is presumably due to the use of visual mode. To repeat the operation using a macro, do this:
qqV"0pq
The macro can then be repeated by pressing #q or ##.
EDIT 2: repeating using .
Here's an attempt at making it repeatable using . by not using visual mode. After yanking the stamp line and moving the cursor, do this:
"_S<c-r>0<delete>
which uses the insert mode <c-r> command to insert the contents of register 0. Note that the <delete> is necessary because the stamp line contained a carriage return. If it did not (i.e. yanking using y$ rather than yy) the <delete> could be omitted.
I don't think you are going to reach your goal without at least a little bit of "remapping".
I've been using this one for a "long" time:
vnoremap <leader>p "_dP
p and P still work as usual and I simply hit ,p over a visual selection when I want to repeat the same paste later. You could also map a single function key to make the whole thing quicker.
Also, do you know about the c flag for substitutions?
:%s/coconut/blueberry/c
will ask for your confirmation for each match.
Many answers here outline the general keys or commands. I've turned them into my ReplaceWithRegister plugin, which also handles many corner cases, and allows quick repeat via the . command. I also use your described create stamp and replace technique often, and found my script indispensable. Should you not like it, the plugin page also has links to alternative plugins.
A really easy solution: just put this script in your .vimrc, then toggle off the "buffer-overwriting" side-effect behavior of the delete key by typing ,, (two commas) to enter "no side effects" mode.
In this mode your workflow now works exactly as you described: yank whatever you like, then select, paste, and delete freely and repeatedly -- your buffer always remains intact. Then type ,, again if you wish to restore vim's normal buffer-altering behavior.
The script is the accepted answer here:
vim toggling buffer overwrite behavior when deleting
One can resort to Ex commands to achieve the said workflow.
For a single substitution, yank the “stamp” line (with yy, Vy,
:y, or otherwise), then repeatedly use the combination of the
:put and :delete commands:
:pu|-d_
Like any other Ex command, this one can be easily repeated with the
#: shortcut (see :help #:) — unless another Ex command was issued
in the meantime (in which case that command would be repeated instead).
Of course, you can also record the above Ex command as a macro and
invoke it that way, too.
Starting with your cursor at the start of the line to be duplicated:
y$ to yank the whole line (excluding the linefeed).
j and k to advance to the next line to be replaced (repeating as needed)
Replace the line with your yanked text
C<c-r>0<esc>0 (first time)
. (subsequent times)
If there are more lines to be replaced, goto 2.
The cursor will remain in column zero after each step.
I have the following characters being repeated at the end of every line:
^[[00m
How can I remove them from each line using the Vim editor?
When I give the command :%s/^[[00m//g, it doesn't work.
You could use :%s/.\{6}$// to literally delete 6 characters off the end of each line.
The : starts ex mode which lets you execute a command. % is a range that specifies that this command should operate on the whole file. The s stands for substitute and is followed by a pattern and replace string in the format s/pattern/replacement/. Our pattern in this case is .\{6}$ which means match any character (.) exactly 6 times (\{6}) followed by the end of the line ($) and replace it with our replacement string, which is nothing. Therefore, as I said above, this matches the last 6 characters of every line and replaces them with nothing.
I would use the global command.
Try this:
:g/$/norm $xxxxxx
or even:
:g/$/norm $5Xx
I think the key to this problem is to keep it generic and not specific to the characters you are trying to delete. That way the technique you learn will be applicable to many other situations.
Assuming this is an ANSI escape sequence, the ^[ stands for a single <Esc> character. You have to enter it by pressing Ctrl + V (or Ctrl + Q) on many Windows Vim installations), followed by Esc. Notice how this is then highlighted in a slightly different color, too.
It's easy enough to replace the last six characters of every line being agnostic to what those characters are, but it leaves considerable room for error so I wouldn't recommend it. Also, if ^[ is an escape character, you're really looking for five characters.
Escape code
Using ga on the character ^[ you can determine whether it's an escape code, in which case the status bar would display
<^[> 27, Hex 1b, Octal 033
Assuming it is, you can replace everything using
:%s/\%x1b\[00m$//gc
With \%x1b coming from the hex value above. Note also that you have to escape the bracket ([) because it's a reserved character in Vim regex. $ makes sure it occurs at the end of a line, and the /gc flags will make it global and confirm each replacement (you can press a to replace all).
Not escape code
It's a simple matter of escaping then. You can use either of the two below:
:%s/\^\[\[00m$//gc
:%s/\V^[[00m\$//gc
If they are all aligning, you can do a visual-block selection and delete it then.
Otherwise, if you have a sequence unknown how to input, you can visually select it by pressing v, then mark and yank it y (per default into register "). Then you type :%s/<C-R>"//g to delete it.
Note:
<C-R>" puts the content of register " at the cursor position.
If you yanked it into another register, say "ay (yank to register a - the piglatin yank, as I call it) and forgot where you put it, you can look at the contents of your registers with :reg.
<C-R> is Vim speak for Ctrl+R
This seems to work fine when the line is more than 5 chars long:
:perldo $_ = substr $_, 0, -5
but when the line is 5 or less chars long it does nothing.
Maybe there is a easy way in perl to delete the last 5 chars of a string, but I don't really know it:)
Use this to delete:
:%s/^[[00m//gc
Say I have ten lines and I want to prepend text to some word that occurs in those lines? It does not have to be at the beginning of the line.
From:
sdfsd foo sdfsd
sfsd foo fsdf
sdfsdf foo sdfsdf
to:
sdfsd bar(foo sdfsd
sfsd bar(foo fsdf
sdfsdf bar(foo sdfsdf
Is it also possible to not only prepend the bar( but actually surround foo with bar(foo)?
I would also like a quick way to append // comments to multiple lines (C-style comments).
I use Vim/GVim 7.2.
Go to the first foo, press Ctrl-v to enter visual block mode and press down until all the lines with foo are marked. Then press Shift-i to insert at the beginning (of the block). When you are finished and press Esc, the inserted characters will be added to each line at the left of the marked block.
To insert at the end, press again Ctrl-v, move up/down to mark all affected lines and then press End or $ to extend the selection until the end of the lines. Now you can press Shift-a to append at the end of all the lines, just like previously with Shift-i.
The visual selection can also be done with normal movement commands. So to comment a whole block in C you could move to the opening brace and type Ctrl-v % Shift-i // Esc.
To answer your first question, the below
:%s/foo/bar(&)/g
will look for foo, and surround the matched pattern with bar(). The /g will do this multiple times in one line.
Since you're just matching foo, you could do a simple :s/foo/bar(foo)/g. The above will work, however, if you decide to match on a regular expression rather than a simple word (e.g. f[a-z][a-z]). The '&' in the above represents what you've matched.
To prefix a set of lines I use one of two different approaches:
One approach is the block select (mentioned by sth). In general, you can select a rectangular region with ctrl-V followed by cursor-movement. Once you've highlighted a rectangle, pressing shift-I will insert characters on the left side of the rectangle, or shift-A will append them on the right side of the rectangle. So you can use this technique to make a rectangle that includes the left-most column of the lines you want to prefix, hit shift-I, type the prefix, and then hit escape.
The other approach is to use a substitution (as mentioned by Brian Agnew). Brian's substitution will affect the entire file (the % in the command means "all lines"). To affect just a few lines the easiest approach is to hit shift-V (which enables visual-line mode) while on the first/last line, and then move to the last/first line. Then type:
:s/^/YOUR PREFIX/
The ^ is a regex (in this case, the beginning of the line). By typing this in visual line mode you'll see '<,'> inserted before the s automatically. This means the range of the substitution will be the visual selection.
Extra tip: if your prefix contains slashes, you can either escape them with backslash, or you can use a different punctuation character as the separator in the command. For example, to add C++ line comments, I usually write:
:s:^:// :
For adding a suffix the substitution approach is generally easier unless all of your lines are exactly the same length. Just use $ for the pattern instead of ^ and your string will be appended instead of pre-pended.
If you want to add a prefix and a suffix simultaneously, you can do something like this:
:s/.*/PREFIX & SUFFIX/
The .* matches the whole line. The & in the replacement puts the matched text (the whole line) back, but now it'll have your prefix and suffix added.
BTW: when commenting out code you'll probably want to uncomment it later. You can use visual-block (ctrl-V) to select the slashes and then hit d to delete them, or you can use a substitution (probably with a visual line selection, made with shift-V) to remove the leading slashes like this:
:s:// ::
:normal to the rescue!
:%norm Wibar(
:%norm WEa)
:norm(al) replays the commands as if you had typed them:
W - goes to the next word
i - starts insertion mode
bar( - types the sequence 'bar('
Or in one line:
:%norm Wibar(ctrlvESCEa)
If you're running Windows then type ctrlq instead of ctrlv.
Yet another possibility (probably not-so-useful in your test case, but handy in other situations) is to cordon off the area you want to change with marks.
Put the cursor anywhere in the top line and press 'a
Put the cursor anywhere in the last line and press 'b
Issue the command :'a,'b s/foo/bar(&)/
I usually like visual block mode if everything is visible on the screen, and I usually prefer marks if the start and stop are separated by many screens.
Another simple regular expression is:
%s/^/<text you want to prepend>/
For the C-style comments, use the regexp answer by Brian, and match on line ending $, and insert away.
Say I have the following style of lines in a text file:
"12" "34" "some text "
"56" "78" "some more text"
.
.
.
etc.
I want to be able to remove the quotes surrounding the first two columns. What is the best way to do this with Vim (I'm currently using gVim)?
I figured out how to at least delete the beginning quote of each line by using visual mode and then enter the command '<,'>s!^"!!
I'm wondering if there is a way to select an entire column of text (one character going straight down the file... or more than 1, but in this case I would only want one). If it is possible, then would you be able to apply the x command (delete the character) to the entire column.
There could be better ways to do it. I'm looking for any suggestions.
Update
Just and FYI, I combined a couple of the suggestions. My _vimrc file now has the following line in it:
let #q=':%s/"\([0-9]*\)"/\1/g^M'
(Note: THE ^M is CTRLQ + Enter to emulate pressing the Enter key after running the command)
Now I can use a macro via #q to remove all of the quotes from both number columns in the file.
use visual block commands:
start mode with Ctrl-v
specify a motion, e.g. G (to the end of the file),
or use up / down keys
for the selected block specify an action, e.g. 'd' for delete
For more see
:h visual-mode
Control-V is used for block select. That would let you select things in the same character column.
It seems like you want to remove the quotes around the numbers. For that use,
:%s/"\([0-9]*\)"/\1/g
Here is a list of what patterns you can do with vim.
There is one more (sort of ugly) form that will restrict to 4 replacements per line.
:%s/^\( *\)"\([ 0-9]*\)"\([ 0-9]*\)"\([ 0-9]*\)"/\1\2\3\4/g
And, if you have sed handy, you can try these from the shell too.
head -4 filename.txt | sed 's/pattern/replacement/g'
that will try your command on the first 4 lines of the file.
Say if you want to delete all columns but the first one, the simple and easy way is to input this in Vim:
:%!awk '{print $1}'
Or you want all columns but the first one, you can also do this:
:%!awk '{$1="";$0=$0;$1=$1;print}'
Indeed it requires external tool to accomplish the quest, but awk is installed in Linux and Mac by default, and I think folks with no UNIX-like system experience rarely use Vim in Windows, otherwise you probably known how to get a Windows version of awk.
Although this case was pretty simple to fix with a regex, if you want to do something even a bit more advanced I also recommend recording a macro like Bryan Ward. Also macros come easier to me than remembering which characters need to be escaped in vim's regexes. And macros are nice because you can see your changes take place immediately and work on your line transformation in smaller bits at a time.
So in your case you would have pressed qw to start recording a macro in register w (you can of course use any letter you want). I usually start my macros with a ^ to move to the start of the line so the macro doesn't rely on the location of the cursor. Then you could do a f" to jump to the first ", x to delete it, f" to jump to the next " and x to delete that too. Then q to finish recording.
Instead of making your macro end on the next line I actually as late as today figured out you can just V (visually line select) all lines you want to apply your macro to and execute :normal #w which applies your macro in register w to each visually selected line.
See column editing in vim. It describes column insert, but basically it should work in the same way for removing.
You could also create a macro (q) that deletes the quotes and then drops down to the next line. Then you can run it a bunch of times by telling vi how many times to execute it. So if you store the macro to say the letter m, then you can run 100#m and it will delete the quotes for 100 lines. For some more information on macros:
http://vim.wikia.com/wiki/Macros
The other solutions are good. You can also try...
:1,$s/^"\(\w\+\)"/\1/gc
For more Vim regex help also see http://vim.wikia.com/wiki/Search_patterns.
Start visual-block by Ctrl+v.
Jump at the end and select first two columns by pressing: G, EE.
Type: :s/\%V"//g which would result in the following command:
:'<,'>s/\%V"//g
Press Enter and this will remove all " occurrences in the selected block.
See: Applying substitutes to a visual block at Vim Wikia
In Unix the ^ allows you to repeat a command with some text substituted for new text. For example:
csh% grep "stuff" file1 >> Results
grep "stuff" file1
csh% ^file1^file2^
grep "stuff" file2
csh%
Is there a Vim equivalent? There are a lot of times I find myself editing minor things on the command line over and over again.
Specifically for subsitutions: use & to repeat your last substitution on the current line from normal mode.
To repeat for all lines, type :%&
q: to enter the command-line window (:help cmdwin).
You can edit and reuse previously entered ex-style commands in this window.
Once you hit :, you can type a couple characters and up-arrow, and it will character-match what you typed. e.g. type :set and it will climb back through your "sets". This also works for search - just type / and up-arrow. And /abc up-arrow will feed you matching search strings counterchronologically.
There are 2 ways.
You simply hit the . key to perform an exact replay of the very last command (other than movement). For example, I type cw then hello to change a word to "hello". After moving my cursor to a different word, I hit . to do it again.
For more advanced commands like a replace, after you have performed the substition, simply hit the : key then the ↑ up arrow key, and it fills your command line with the same command.
To repeat the previous substition on all lines with all of the same flags you can use the mapping g&.
If you have made a substitution in either normal mode :s/A/B/g (the current line) or visual mode :'<,>'s/A/B/g (lines included in the current selection) and you want to repeat that last substitution, you can:
Move to another line (normal mode) and simply press &, or if you like, :-&-<CR> (looks like :&), to affect the current line without highlighting, or
Highlight a range (visual mode) and press :-&-<CR> (looks like :'<,'>&) to affect the range of lines in the selection.
With my limited knowledge of Vim, this solves several problems. For one, the last visual substitution :'<,'>s/A/B/g is available as the last command (:-<UP>) from both normal and visual mode, but always produces an error from normal mode. (It still refers to the last selection from visual mode - not to the empty selection at the cursor like I assumed - and my example substitution exhausts every match in one pass.) Meanwhile, the last normal mode substitution starts with :s, not :'<,'>s, so you would need to modify it to use in visual mode. Finally, & is available directly from normal mode and so it accepts repetitions and other alternatives to selections, like 2& for the next two lines, and as user ruohola said, g& for the entire file.
In both versions, pressing : then & works as if you had pressed : and then retyped s/A/B/, so the mode you were in last time is irrelevant and only the current cursor line or selection determines the line(s) to be affected. (Note that the trailing flags like g are cleared too, but come next in this syntax too, as in :&g/: '<,'>&g. This is a mixed blessing in my opinion, as you can/must re-specify flags here, and standalone & doesn't seem to take flags at all. I must be missing something.)
I welcome suggestions and corrections. Most of this comes from experimentation just now so I'm sure there's a lot more to it, but hopefully it helps anyway.
Take a look at this: http://vim.wikia.com/wiki/Using_command-line_history for explanation.
