Replace whole line containing a string using Sed
sed, shell, string
Solution
You can use the change command to replace the entire line, and the `-i` flag to make the changes in-place. For example, using GNU sed:
sed -i '/TEXT_TO_BE_REPLACED/c\This line is removed by the admin.' /tmp/foo
Problem
I have a text file which has a particular line something like ``` sometext sometext sometext TEXT_TO_BE_REPLACED sometext sometext sometext ``` I need to replace the whole line above with ``` This line is removed by the admin. ``` The search keyword is `TEXT_TO_BE_REPLACED` I need to write a shell script for this. How can I achieve this using `sed`?
