The `rename` Command: Bulk File Renaming Made Easy

Challenge: You need to rename multiple files in a directory with a common pattern, but doing it one by one is tedious and error-prone.

The Solution: Utilize the `rename` command, a powerful tool for batch file renaming using Perl regular expressions.

rename 's/old_pattern/new_pattern/' file_pattern

Why it works: This command takes a Perl expression to find and replace patterns within filenames. `s/old_pattern/new_pattern/` is the substitution operator, and `file_pattern` specifies which files to apply the rename to (e.g., `*.txt`).

Pro-Tip: Use the `-n` (no-action) flag first to preview the changes without actually renaming any files: rename -n 's/old_pattern/new_pattern/' file_pattern.
