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

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

Count lines of code across multiple file types, sorted by least amount of code to greatest
Gives you a nice quick summary of how many lines each of your files is comprised of. (In this example, we just check .c, .h, .php and .pl). Since we just use wc -l to count, you'll just get a very rough estimate of how many lines of actual code there are. Use a more sophisticated algorithm instead if you need to.

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

Random quote from Borat
I improved a bit on the original by only using sed and extracting the quote with a matching group. Use -nE for sed on Mac OSX Use -nr for sed on Linux. Warning! The quotes from Borat are definitely offensive.

List the size of all sub folders and files from the current location, with sorting

checking space availabe on all /proc/mounts points (using Nagios check_disk)

ionice limits process I/O, to keep it from swamping the system (Linux)
This command is somewhat similar to 'nice', but constrains I/O usage rather than CPU usage. In particular, the '-c3' flag tells the OS to only allow the process to do I/O when nothing else is pending. This dramatically increases the responsiveness of the rest of the system if the process is doing heavy I/O. There's also a '-p' flag, to set the priority of an already-running process.

list all hd partitions
Only one command and not dependant on full read access to the devices.
