Cipher.c
This is a simple substitution cipher that I wrote with the help of Nick Hollet (aka. Niax). It either encrypts a file, or decrypts it, depending on whether you use the -decrypt or the -encrypt flag. It outputs to stdout, but you can change that to a file by using the "> outputfile" arguement at the end of running the script.
There isn't a filesize limit, and the cipher supports this charset:
!"#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ [\]^_`abcdefghijklmnopqrstuvwxyz{|}*
Usage
Compile The Code:
gcc /path/to/cipher.c -o cipher
Encrypt A File:
./cipher -encrypt /path/to/plaintext/file
Decrypt A File:
./cipher -decrypt /path/to/encrypted/file

FindNew.pl
This script was designed to copy new songs that I had added into my iTunes library into a separate directory (so that I could back them up), but it could easily be modified to work with other files apart from songs. The settings for this are set in the beginning of the script.
Usage
./FindNew.pl
