Convert PDF to JPG
(relies on 'imagemagick') This command will convert all .pdf files in a directory into a 800px (wide or height, whichever is smaller) image (with the aspect ratio kept) .jpg. If the file is named 'example1.pdf' it will be named 'example1.jpg' when it is complete. This is a VERY worthwhile command! People pay hundreds of dollars for this in the Windows world. My .jpg files average between 150kB to 300kB, but your's may differ.

Using ASCII Art output on MPlayer
Not so useful. Just a cool feature.

copies 20 most recently downloaded mp3 files (such as from Miro) into a directory
Change ~/tmp to the destination directory, such as your mounted media. Change -n20 to whatever number of files to copy. It should quit when media is full. I use this to put my most recently downloaded podcasts onto my phone.

Create colorized html file from Vim or Vimdiff
While editing a source file in vim, or using vimdiff to compare two or more files, the ':TOhtml' command can be used to export each buffer as an html file, including syntax highlighting and vimdiff colorization. If you are in insert mode in vim, you will have to type :TOhtml This will open a new buffer filled with html, which you can then save.

Shows all block devices in a tree with descruptions of what they are.

Advanced python tracing
Trace python statement execution and syscalls invoked during that simultaneously

Copy files and directories from a remote machine to the local machine
This command will copy files and directories from a remote machine to the local one. Ensure you are in the local directory you want to populate with the remote files before running the command. To copy a directory and it's contents, you could: $ ssh user@host "(cd /path/to/a/directory ; tar cvf - ./targetdir)" | tar xvf - This is especially useful on *nix'es that don't have 'scp' installed by default.
