cli-sedHow can I use the sed command line tool to modify file permissions?


Using the sed command line tool, you can modify file permissions by using the chmod command. For example, if you wanted to give read and write permissions to all users for a file named test.txt, you could use the following code:

sed -i 's/test.txt/chmod 666 test.txt/g'

This would change the permissions of test.txt to 666, giving read and write permissions to all users.

The code can be broken down as follows:

  • sed - the command line tool used for modifying file permissions
  • -i - the option used to edit the file in place
  • s/test.txt/chmod 666 test.txt/g - the substitution command, which replaces test.txt with chmod 666 test.txt
