I run below sed command
sed -i s/abc=.*$/abc=def ghi/g hpq_sf_attach_wf_param.txt
and it gave me error:
sed: -e expression #1, char 17: unterminated `s' command
I noticed it is due to space in between of def and ghi.
Any idea how to fix it?
You need to use quoting to protect special characters, including spaces, $, and *.
sed -i 's/abc=.*$/abc=def ghi/g' hpq_sf_attach_wf_param.txt
So geekosaur had it right. The the reason you had the problem though is because it needs to be double quotes for the wildcards because with single quotes it takes them as literal characters, not for the meaning you want.
sed -i "s/abc=.*$/abc=def ghi/g" hpq_sf_attach_wf_param.txt
Also if the space between "def" and "ghi" gives you problems, adding a "\" should help making it read it as a literal space.
sed -i "s/abc=.*$/abc=def\ ghi/g" hpq_sf_attach_wf_param.txt

I am trying to use sed to replace the expression 'root'#'localhost' with 'root'#'%' with no success. Could someone please help me with the command?
I tried the following:
sed -i ’s#\’root\’#\’localhost\’#\’root\’#\’%\’#g’ xyz.sql
sed: -e expression #1, char 1: unknown command: `?'
sed -i -e ’s/localhost/%/g’ xyz_2616.sql
sed: -e expression #1, char 1: unknown command: `?'
First, make sure you're using a single quote. ’ (a.k.a. ’ or unicode 8217) is not the same as ASCII character 39, '.
Next, you can't escape single quotes inside single quotes. Here's an answer I wrote about that some time ago.
You can, however, put single quotes inside double quotes, or escape them outside your single quoted string. For example, either of the following might work:
sed -e "s/'root'#'localhost'/'root'#'%'/g" file.sql
or
sed -e 's/'\''root'\''#'\''localhost'\''/'\''root'\''#'%'\''/g' file.sql
Alternately, you could substitute just the portion you're interested in, trusting that it doesn't appear elsewhere on the same line:
sed -e '/root.#.localhost/s/localhost/%/' file.sql
The ’ character doesn't look like a single quote (') to me. Make sure that you are using single quotes.
The character you're actually typing is a "right single quote mark". What we refer to as a "single quote" is actually an "apostrophe".
The following should work:
sed -e 's/localhost/%/g' rice_2616.sql
or, your first alternatives but with double quotes to avoid having to escape the embedded single quotes (which I presume are apostrophes):
sed -e "s/'root'#'localhost'/'root’#'%'/g" rice_2616.sql
Good-day,
In a Bash shell script I'm putting together, I am trying to find this text: /usr/local/freeswitch/log/freeswitch.log and replace it with: /var/log/freeswitch/freeswitch.log in this file: /etc/fail2ban/jail.local
This is what I have tried so far, both of which result in the error: sed: -e expression #1, char 75: unterminated `s' command
Attempt #1
sed -i 's~usr/local/freeswitch/log/freeswitch.log~var/log/freeswitch/freeswitch.log' /etc/fail2ban/jail.local
Attempt #2
sed -i 's~usr/local/freeswitch/log/freeswitch.log/var/log/freeswitch/freeswitch.log' /etc/fail2ban/jail.local
My research shows that since the text I'm searching for includes the "/" character, I should be using a different delimiter "~" to separate the find and replace strings. But looks like I'm doing something wrong, any assistance would be appreciated, thanks.
The structure of a sed substitution command is s/PATTERN/REPLACEMENT/ (note the delimiter at the end of the command).
You're right, you can change the delimiter to a different character, so if you're going to use ~ you need to put one of those at the end of the command.
I have a problem with sed. I want to replace the entire specific line number for multiple lines in multiples documents.
This the bash command for 1 specific line in 1 specific document:
BNAME=$(basename $FILE .pdb)
psfgen1="pdb ./sedpdb/${BNAME}.pdb/"
sed -i '8s/'.*'/'${psfgen1}'/' ./psfgen.inp
And I get this error :
sed: -e expression #1, char 60: unterminated `s' command
Is anyone know how to solve this issue? Thanks!
I can see two things wrong:
There are forward slashes in the string that you're attempting to use in the sed command. These will be interpreted as part of the command, so you should use a different delimiter.
The * is unquoted, so will be glob-expanded by the shell to the names of all the files in the directory.
Reliably using shell variables in string substitutions is non-trivial but can be done using one of the approaches shown in the answers to this question.
In your case, it looks like you can probably get away with using another character as the delimiter, such as #:
sed -i "8s#.*#${psfgen1}#" ./psfgen.inp
I am trying to substitute a word using sed with two words. For example I'm using:
sed s/TITLE/New Title/ old.txt > new.txt
However, when I run the command the following populates:
sed: -e expression #1, char 17: unterminated `s' command
Any help would be of great appreciation. I've searched everywhere without any clarity.
You are missing quotes. You need to wrap the substitution portion inside quotes like:
sed 's/TITLE/New Title/' old.txt > new.txt
If you are using variables as part of substitution, you'll need to use double quotes " instead of single quotes ' to allow variables to interpolate.
Take a look at sed man page and explore -i option which allows you to make in-place changes.
I'm trying to add some text (a path) at the end of a line which is found by a sed command:
var="/folder1/folder2/folder3"
sed -i "/Begins with this text/s/$/$var/" filename
I know that double quotes are needed to use variables in a sed command but if I use the above command it gives me an error message saying:
expresssion #1, character 23: unknown option to `s
What am I doing wrong?
Change the delimiter in the substitute command to something that won't appear in $var, e.g.
sed -i "/Begins with this text/s|$|$var|" filename
or escape the slashes in $var:
var="\/folder1\/folder2\/folder3"
