Just discovered the rename utility under Linux

Warning: There appears to be two 'rename' utilities one under Debian 6.0.7 works as below and is a Perl utility. The other, which I found on Fedora 19 is part of util-linux, and doesn't work the same way (i.e. it's a lot dumber).

Work-a-round copy /usr/bin/prename from your Debian system to /usr/bin on your Fedora System and run prename instead of rename.

rename
Usage: rename [-v] [-n] [-f] perlexpr [filenames]

# create some test files

myuser@mypc:~/rename_test$ touch file2.txt
myuser@mypc:~/rename_test$ touch file3.pdf
