Extract tarball from internet without local saving

Get own public IP address
Returns your external IP address to the command line using only wget

Get video information with ffmpeg

Get the Volume labels all bitlocker volumes had before being encrypted
Get information of volume labels of bitlocker volumes, even if they are encrypted and locked (no access to filesystem, no password provided). Note that the volume labels can have spaces, but only if you name then before encryption. Renaming a bitlocker partition after being encrypted does not have the same effect as doing it before.

Find broken symlinks and delete them
This command is adapted from http://otomaton.wordpress.com/2012/12/26/find-broken-symbolic-links/ Solutions with $ find -L don't work when the link is a loop, an error message is printed.

Synchronize date and time with a server over ssh
If you are stuck behind a firewall and want to synchronize time with another server but you do not want to port forward NTP (which uses UDP) then this command is handy. It gets the time from a server and sets the local time. It is not that accurate but I can live with a second or so drift.

Tail -f at your own pace
The -s option allows you to specify the update interval

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.

runs a X session within your X session

check remote port without telnet
