Rename files with unique, randomly generated file names

A simple way to rename a set of files to a unique, randomized file name.


There are 3 alternatives - vote for the best!

What others think

Hmm... It works, but it's a bit messy.

First of all, stop mktemp creating files that we don't use:

mktemp -u

Then use bash to replace awk (strip out everything (*) until dot):


That leaves us with:

for i in *.txt; do F=$(mktemp -u); mv "$i" ${F##*.}.txt; done
