I'm getting a
sed: -e expression #1, char 22: unterminated `s' command is there a problem on my script? Also the "oldstring" has special characters
#!bin/bash oldstring='<script>"[oldscript]"</script>' newstring='<script>"[newscript]"</script>' grep -rl $oldstring /path/to/folder | xargs sed -i s/$oldstring/$newstring/g

Find and replace text within a file using sed command Use Stream EDitor (sed) as follows: sed -i 's/old-text/new-text/g' input.txt. The s is the substitute command of sed for find and replace.
This collection of sed and grep use cases might help you better understand how these commands can be used in Linux. Tools like sed (stream editor) and grep (global regular expression print) are powerful ways to save time and make your work faster.
On OS X you will need to change sed -i 's/str1/str2/g' to sed -i "" 's/str1/str2/g' for this to work. @cmevoli with this method, grep goes through all the files and sed only scans the files matched by grep .
As @Didier said, you can change your delimiter to something other than /:
grep -rl $oldstring /path/to/folder | xargs sed -i s@$oldstring@$newstring@g If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
