Renexp

A simple script to rename files in a folder using regular expressions. Does not support recursive searching and renaming at the moment.

Example usage

Input files:

• 1first1.txt
• 2second2.png
• 3third3.exe
• 4fourth4.py

renexp [--sim] "[1-9]([a-z]*)[1-9](\.[a-z]+)?" "\1\2"

Output files:

• first.txt
• second.png
• third.exe
• fourth.py

\1 and \2 are equivalent to the usual $1 and $2

Remember to surround the regular expressions with double quotes.

Use the --sim option to simulate the execution before renaming files definitively
