Pack up some files into a tarball on a remote server without writing to the local filesystem
I recently found myself with a filesystem I couldn't write to and a bunch of files I had to get the hell out of dodge, preferably not one at a time. This command makes it possible to pack a bunch of files into a single archive and write it to a remote server.

Install pip with Proxy
Installs pip packages defining a proxy

Scan for nearby Bluetooth devices.
Scans local area for visible Bluetooth devices. Use 'hcitool inq' to discover the type of device it is. And use -i hciX option to specify the local Bluetooth device to use.

ignore .DS_Store forever in GIT
With a couple of little commands, you?ll be able to ignore the .DS_Store files forever from your git repositories on mac! The following command will add the .gitignore file to the git configuration git config --global core.excludesfile ~/.gitignore then, the following, will add the .DS_Store to the list echo .DS_Store >> ~/.gitignore

find and delete files smaller than specific size

find and grep Word docs
Find Word docs by filename in the current directory, convert each of them to plain text using antiword (taking care of spaces in filenames), then grep for a search term in the particular file. (Of course, it's better to save your data as plain text to make for easier grepping, but that's not always possible.) Requires antiword. Or you can modify it to use catdoc instead.

Sed can refference parts of the pattern in the replacement:

run php code inline from the command line
Most people know that you can run a PHP script from the command line like so: $php ./my_script.php But sometimes I just want to run a quick bit of code, the PHP Command Line Interface allows me to do so with the -r option. Requires package php5-cli

Determine command type (alias, keyword, function, builtin, or file)
Prints a string indicating whether a command is an alias, keyword, function, builtin, or file. I have used this in my BASH scripts to allow an external parameter to define which function to run, and ensure that it is a valid function that can indeed be run.

Transform a portrait pdf in a landscape one with 2 pages per page
This is an example of the usage of pdfnup (you can find it in the 'pdfjam' package). With this command you can save ink/toner and paper (and thus trees!) when you print a pdf. This tools are very configurable, and you can make also 2x2, 3x2, 2x3 layouts, and more (the limit is your fantasy and the resolution of the printer :-) You must have installed pdfjam, pdflatex, and the LaTeX pdfpages package in your box.
