Randomize filenames

Hans-Henry Jakobsen — Fri, 10 Sep 2010 21:18:46 +0000

This is a simple bash script to create random filenames of all jpg-files (*.jpg) in a folder using the linux commands mv, sha1sum and cut.

#!/bin/bash
# Randomize filenames

for fname in *.jpg;
do
        mv "$fname" $(echo "$fname" | \
                sha1sum | \
                cut -f1 -d ' ' | \
                cut -b 1-5).jpg
done

The jpg-files can have names like

08df4.jpg
1e788.jpg
315e6.jpg
41e19.jpg
5f7d0.jpg
7471e.jpg
