check the status of 'dd' in progress (OS X)
"killall -USR1 dd" does not work in OS X for me. However, sending INFO instead of USR1 works.

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

Simplification of "sed 'your sed stuff here' file > file2 && mv file2 file"

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

Remove a range of lines from a file
Deletes lines from START to END, inclusive. For example +4,10d will delete line 4, 5, ..., 10. Just like the vi command :4,10d does it.

Convert tab separate file (TSV) to JSON with jq
With this command you can convert a tab separate file (TSV) into a JSON file with jq. For example, this input.tsv i-0b9adca882e5e6326 172.16.0.188 i-088dd69e5c3624888 172.16.0.102 i-0e70eac180537d4aa 172.16.0.85 will produce the showed output.

Download from Rapidshare Premium using wget - Part 1
In order to do that, first you need to save a cookie file with your account info. These commands do it (maybe you need to create the '.cookies' dir before). Also, you need to check the "Direct downloads" option on the Premium Zone >> Settings tab. You need to do this once (as long you maintain the file or your Rapidshare Premium account).

This version prints current votes and commands for a user. Pass the user as an argument. While this technically "fits" as a one liner, it really is easier to look at as a shell script with extra whitespace. :)

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"
