Top Forums UNIX for Beginners Questions & Answers Find all .sh files in file system and need to replace the string inside .sh files Post 303038025 by jim mcnamara on Wednesday 21st of August 2019 02:25:22 PM

Running find against / (root) is not great idea.

Run your code as a non-privleged user.

Try
Code:
find /  -type f -name '*.sh' -exec grep -l 'vijay@gmail.com'  {} \; > ~/mylist

then check the list. If you like it:
Code:
while read filename 
do
    sed  -i 's/vijay@/vijay.bhaskar@/g' $filename
done  <  ~/mylist

If you hit permission errors then you need to rethink what you are doing because you may have selected system files you should not have changed earlier.
You can run the file loop statement over and over until you are error free. Why? Because will not change anything in files it already fixed.

Check back here if you need help.
Edit:
Rudi beat me to an answer. I still think a little caution is good idea as well.
