Linux: Rename Expression To Remove First Character From a File Name

To remove the first character from a file name in Linux, you can use the ‘rename’ command with a regular expression (regex) pattern. The ‘rename’ command can be used to modify the names of multiple files at once based on a pattern.

Here’s an example that removes the first character from all file names in the current directory:

The above command uses the ‘s’ option to specify a substitution, ‘^.’ to match the first character in the file name, and ‘//’ to replace the match with an empty string, effectively removing the first character.

Note: Make sure to backup your files before running this command, as it can result in unexpected changes to your files if the regex pattern is incorrect.
