randomize hostname and mac address, force dhcp renew. (for anonymous networking)
this string of commands will release your dhcp address, change your mac address, generate a new random hostname and then get a new dhcp lease.

zsh only: access a file when you don't know the path, if it is in PATH
Say you want to execute 'file' on the command 'top' (to determine what type of file it is); but you don't know where 'top' resides: preface the argument with = and zsh will implicitly prepend the path.

url shortner using google's shortner api
First get a api key for google url shortner from here https://developers.google.com/url-shortener/ Then replace the API_KEY in the command

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

Copy a file using dc3dd and watch its progress (very nice alternative to dd)
Requires the dc3dd package - available at http://dc3dd.sourceforge.net

Kill any lingering ssh processes
Also ignoring "sshd" server is necessary since you should not kill ssh server processes.

Cancel all aptitude scheduled actions
Very handy if you have done a package selection mistake in aptitude. Note that it's better to do a Ctrl+U (undo) in aptitude if possible, because the keep-all will clear some package states (like the 'hold' state).

Expand shortened URLs
curl(1) is more portable than wget(1) across Unices, so here is an alternative doing the same thing with greater portability. This shell function uses curl(1) to show what site a shortened URL is pointing to, even if there are many nested shortened URLs. This is a great way to test whether or not the shortened URL is sending you to a malicious site, or somewhere nasty that you don't want to visit. The sample output is from: $ expandurl http://t.co/LDWqmtDM

reclaim your window titlebars (in ubuntu lucid)
