Given some images (jpg or other supported formats) in input, you obtain a single PDF file with an image for every page.

Takes and displays screenshot of Android phone over adb.
Dependencies on phone: adb access, screencap command, base64 command. Dependencies on computer: adb, sed, base64, display (from imagemagick, but can substitute other image viewer which reads from stdin). This should work around adb stupidies (i.e. that it replaces \n with \r\n) with base64.

Create an alias, store it in ~/.bash_aliases and source your new alias into the ~/.bashrc
This is useful if you use a shell with a lot of other users. You will be able to run "topu" to see your running processes instead of the complete 'top -u username'. Read more on alias: http://man.cx/alias

Grep inside Vim and navigate results

Mac OS X - List all of my machine's IP addresses
On the Mac, the format ifconfig puts out is little different from Linux: the IP address is space separated, instead of colon. That makes parsing the IP address easier. See releated command for Linux/Unix: http://www.commandlinefu.com/commands/view/651/getting-the-ip-address-of-eth0

prevents replace an existing file by mistake
Use set +o noclobber and you will be able to replace files again

exec chmod to subfiles
Using `-exec cmd {} +` causes find to build the command using all matching filenames before execution, rather than once per file.
