This script uses the find command to search for all files in the specified directory and its subdirectories. The grep command is used to check if the file contains the search string. If it does, the sed command is used to replace the text in the file. The -i flag is used to edit the files in place, without creating backups. Finally, the script prints the file name to confirm that the text was changed.
You can customize the script by changing the search and replace variables to the text you want to find and replace, and the dir variable to the directory you want to search in.
Note: This script uses the sed command with the -i option which will change the file in place, this could be dangerous if you’re not sure what you’re doing, so please make sure to backup your files or test the script with a small set of files first.
