export iPad App list to txt file
This will generate the same output without changing the current directory, and filepath will be relative to the current directory. Note: it will (still) fail if your iTunes library is in a non-standard location.

Simple XML tag extract with sed
Limited, but useful construct to extract text embedded in XML tags. This will only work if bar is all on one line. If nobody posts an alternative for the multiline sed version, I'll figure it out later...

list files recursively by size

Copy one file to multiple files
Copies file.org to file.copy1 ... file.copyn

Search and replace in multiple files recursively
Replace "foo" with "bar" in all files in current directory recursively

Convert CSV to JSON
Replace 'csv_file.csv' with your filename.

simple backup with rsync
With this cron, rsync begins to sinchronize the contents of the local directory on /[VIPdirectory] with the directory /backup/[VIPdirectory] on the remote server X.X.X.X. Previously we need working on public/private-keys ssh to guarantee the acces to the remote server on X.X.X.X
