Backup with versioning
Apart from an exact copy of your recent contents, also keep all earlier versions of files and folders that were modified or deleted. Inspired by EVACopy http://evacopy.sourceforge.net

What is my public IP-address?
Short command, easy to remember

Colorized grep in less
Get your colorized grep output in less(1). This involves two things: forcing grep to output colors even though it's not going to a terminal and telling less to handle those properly.

It decripts all pgp files in a selection folder and move the output into a file.

Dump root ext3 fs over ssh
...can do similar w/ tar, dd, xfsdump, e2fsdump, etc.

Renaming a file without overwiting an existing file name
Sometimes in a hurry you may move or copy a file using an already existent file name. If you aliased the cp and mv command with the -i option you are prompted for a confirmation before overwriting but if your aliases aren't there you will loose the target file! The -b option will force the mv command to check if the destination file already exists and if it is already there a backup copy with an ending ~ is created.

Easily run a program in the background without losing output
This function runs a program in the background, and logs all output to an automatically created logfile. That way, you can still get at the output without it clogging up your terminal. Tip: Throw fork() and this: $for prog in firefox kate konqueror ;do alias $prog="fork $prog";done into your bashrc, so that they'll automatically run out of the way.

Mount proc
Run this in / in a chroot to get your own proc there.

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

rgrep: recursive grep without .svn
Only excludes .svn from filenames.
