Upload a video to youtube

Google just released a new commend line tool offering all sorts of new services from the commend line. One of them is uploading a youtube video but there are plenty more google services to interact with. Download it here: http://code.google.com/p/googlecl/ Manual: http://code.google.com/p/googlecl/wiki/Manual

Clean up poorly named TV shows.

Replace 'SHOWNAME' with the name of the TV show. Add -n to test the command without renaming files. Check the 'sample output'.

Set a user password without passwd

Slightly shorter. It doesn't create a subprocess either.

Include a remote file (in vim)

Like vim scp://yourhost//your/file but in vim cmds.

Find passwords that has been stored as plain text in NetworkManager

Find usb device

I often use it to find recently added ou removed device, or using find in /dev, or anything similar. Just run the command, plug the device, and wait to see him and only him

kill process by name

Or even easier, if it's available: $ killall firefox I have no idea why you would want to rely on two unusual dependencies to do something that can be done a hundred ways from coreutils...

Extract all 7zip files in current directory taking filename spaces into account

Generate random password on Mac OS X

Feel free to put this in your ~/.profile: $ random(){ cat /dev/urandom | env LC_CTYPE=C tr -dc $1 | head -c $2; echo; } Then use it to generate passwords: $ random [:alnum:] 16 Or DNA sequences: $ random ACGT 256

Google verbatim search on your terminal

Put it in your ~/.bashrc usage: google word1 word2 word3... google '"this search gets quoted"'
