recursive base64 encoding -- Cipher for the Poor ?
Just for fun, I searched a simple way to encrypt some text. Simple base64 encoding seemed a good start so I decided to "amplify" encoding using repeted base64 encoding. Of course, this is not really secure but can be useful to hide datas to most part of humans ;). Do not hesitate to provide better solutions or else.

Create incremental backups of individual folders using find and tar-gzip
Problem: I wanted to backup user data individually, using and incremental method. In this example, all user data is located in "/mnt/storage/profiles", and about 25 folders inside, each with a username ( /mnt/storage/profiles/mike; /mnt/storage/profiles/lucy ...) I need each individual folder backed up, not the whole "/mnt/storage/profiles". So, using find while excluding directories depth and creating two variables (tarfile=username & desdir=destination), tar will create a .tgz file for each folder, resulting in a "mike_2013-12-05.tgz" and "lucy_2013-12-05.tgz".
