Install pip with Proxy
Installs pip packages defining a proxy

Remove annoying files from recently extracted zip archive
Inspired by http://www.commandlinefu.com/commands/view/2573/remove-all-files-previously-extracted-from-a-tar.gz-file. .... yet for zip files

Copy with progress

Update zone file Serial numbers
Will edit *.db files in the same directory with todays date. Useful for doing a mass update to domains on a nameserver, adding spf records, etc. Looks for a string starting with 200 or 201 followed by 7 numbers, and replaces with todays date. This won't overwrite Ip's but i would still do some double checking after running this. Make sure your server's date is correct, otherwise insert your own serial number. $rndc reload should usually follow this command.

Run a long job and notify me when it's finished
You will need libnotify-bin for this to work: $ sudo aptitude install libnotify-bin

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

A "Web 2.0" domain name generator and look for register availability
You would need pwgen installed first, on ubuntu you can get it by apt-get $ sudo apt-get install pwgen

Open Remote Desktop (RDP) from command line having a custom screen size
This example uses xfreerdp, which builds upon the development of rdesktop. This example usage will also send you the remote machine's sound.

Find status of all symlinks
The symlinks command can show status of all symbolic links, including which links are dangling, which symlinks point to files on other file systems, which symlinks use ../ more than necessary, which symlinks are messy (e.g. having too many slashes or dots), etc. Other useful things it can do include removing all dangling links (-d) and converting absolute links to relative links (-c). The path given must be an absolute path (which is why I used $(pwd) in the example command).

List upgrade-able packages on Ubuntu
Taken from apticron and modified.
