I need to replace a string in a lot of files in a folder, with only ssh access to the server. How can I do this?
for example i want replace all files Which contains code
<script src='http://cdn.adplxmd.com/adplexmedia/tags/xbanner/xbanner.js?ap=1300' type='text/javascript'></script>
I want replace it with my name: sultan
I do something like this:
sed -i 's/<script src='http://cdn.adplxmd.com/adplexmedia/tags/xbanner/xbanner.js?ap=1300' type='text/javascript'></script>/sultan/g' *
but the problem i see error message in linux commands:
sed: -e expression #1, char 20: unknown option to `s'
How do I fix this problems?
There are two errors:
the slash is used as a delimiter in your call to sed, so this ambiguity needs to be resolve
you're using single quotes in the search term but also to enclose the sed parameter.
You can try something like this instead:
sed -i "s|<script src='http://cdn.adplxmd.com/adplexmedia/tags/xbanner/xbanner.js?ap=1300' type='text/javascript'></script>|sultan|g" *

When I try following command, I'd like to rewrite sql.
Day='2020/12/1'
Dir=/home/test/data
sql=`cat $Dir"/"$test".sql" | sed -e "s/Day/$Day/g"`
I suffered following errors.
sed: -e expression #1, char 24: unknown option to `s'
Why the s is recognised as option ? why is this command couldnt work well ?
if someone has opinoin, please let me know
Thanks
The problem is with slashes: your variable contains them and the final command will be something like sed "s/string/path/to/something/g", containing way too many slashes.
Since sed can take any char as delimiter (without having to declare the new delimiter), you can try using another one that doesn't appear in your replacement string like below:
sql=`cat $Dir"/"$test".sql" | sed -e "s|Day|$Day|g"`
Also, you would need to use sed -i to update the file in-place, since it looks like that is what you're trying to do.
Good-day,
In a Bash shell script I'm putting together, I am trying to find this text: /usr/local/freeswitch/log/freeswitch.log and replace it with: /var/log/freeswitch/freeswitch.log in this file: /etc/fail2ban/jail.local
This is what I have tried so far, both of which result in the error: sed: -e expression #1, char 75: unterminated `s' command
Attempt #1
sed -i 's~usr/local/freeswitch/log/freeswitch.log~var/log/freeswitch/freeswitch.log' /etc/fail2ban/jail.local
Attempt #2
sed -i 's~usr/local/freeswitch/log/freeswitch.log/var/log/freeswitch/freeswitch.log' /etc/fail2ban/jail.local
My research shows that since the text I'm searching for includes the "/" character, I should be using a different delimiter "~" to separate the find and replace strings. But looks like I'm doing something wrong, any assistance would be appreciated, thanks.
The structure of a sed substitution command is s/PATTERN/REPLACEMENT/ (note the delimiter at the end of the command).
You're right, you can change the delimiter to a different character, so if you're going to use ~ you need to put one of those at the end of the command.
I have a problem with sed. I want to replace the entire specific line number for multiple lines in multiples documents.
This the bash command for 1 specific line in 1 specific document:
BNAME=$(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 have a file, and I am trying to use bask to replace all the contents of a substring with a path.
I can use the command:
sed -i s/{WORKSPACE}/$MYVARIABLE/g /var/lib/jenkins/jobs/MY-JOB/workspace/config/params.ini
My config/params.ini looks like:
[folders]
folder1 = {WORKSPACE}/subfolder1
folder2 = {WORKSPACE}/subfolder2
however, when $MYVARIABLE is a path, it fails (containing slashes), the sed command fails with:
sed: -e expression #1, char 16: unknown option to `s'
When I run through it manually, I see that the $MYVARIABLE needs to have it's path-slashes escaped. How can I modify my sed command to incorporate an escaped version of $MYVARIABLE?
There's nothing saying you have to use / as your delimiter. sed will use (almost) anything you stick in there. I have a tendency to use |, since that never (rarely?) appears in a path.
sridhar#century:~> export boong=FLEAK
sridhar#century:~> echo $PATH | sed "s|/bin|/$boong|g"
~/FLEAK:/usr/local/FLEAK:/usr/local/sbin:/usr/local/games:/FLEAK:/sbin:/usr/FLEAK:/usr/sbin:/usr/games:/usr/lib/lightdm/lightdm:/home/oracle/app/oracle/product/12.1.0/server_1/FLEAK

Using double-quotes will allow the shell to do the variable-substitution.
Just escape the $ sign, and use a different delimiter:
sed -i 's;{WORKSPACE};\$MYVARIABLE;g' your_file
I'm trying to replace instances of {$pear_root} in a config file with the $PEAR_ROOT variable in a shell script.
Using the method from here under "A Note About Bash Escape Character" I have:
ESC_PEAR_ROOT="${PEAR_ROOT//\//\\/}"
sed -i "s/{\$pear_root}/${ESC_PEAR_ROOT}/"../.serverconfig/test.txt
I'm getting back 34: Bad substitution which I think may mean that this is unsupported.
The problem seems to be the use of s/find/replace/, as I get the same error whether doing this with sed or with perl.
What is the simplest way to do this:
APP_ROOT=$(php ./scripts/get_realpath.php '../')
PEAR_ROOT="$APP_ROOT/pear"
ESC_PEAR_ROOT="${PEAR_ROOT//\//\\/}"
sed -e "s/{\$pear_root}/${ESC_PEAR_ROOT}/"../.serverconfig/test.txt
And end up with all instances of {$pear_root} in test.txt replaced with the path from PEAR_ROOT?
I'm not attached to this method - anything reliable will do.
This is a bit silly, but I notice you're missing a space between the end of your expression and the name of the file to which you wish to apply it.
/tmp $ sed -e 's/{$pear_root}/'"$PATH"'/' test
/tmp $ sed -e 's/{$pear_root}/'"$PATH"'/'test
sed: bad option in substitution expression
Ok, solved it.
The problem was:
This:
ESC_PEAR_ROOT="${PEAR_ROOT//\//\\/}"
Should have been this:
ESC_PEAR_ROOT="{PEAR_ROOT//\//\\/}"
That was what was causing my "bad substitution" error.
Also, realized I didn't need to escape, since I could just use a different delimiter to s, so I don't even need that line.
Final result ended up as:
APP_ROOT=$(php ./scripts/get_realpath.php '../')
PEAR_ROOT="$APP_ROOT/pear"
sed -i "s#{\$pear_root}#${PEAR_ROOT}#g" ../.serverconfig/test.txt
