Get the /dev/disk/by-id fragment for a physical drive

This was tested on Ubuntu 12.04 (Precise) LTS Server. It returns the name of the symlink within /dev/disk/by-id for the physical drive you specify. Change /dev/sda to the one you want, and replace ata- with scsi- or the appropriate type for your drive.

I used this to pre-configure grub-pc during a non-interactive install because I had to tell it which disk to install grub on, and physical disks don't have a UUID such as that blkid provides.

Hide files in ls, by adding support for .hidden files!

Sometimes I would like to see hidden files, prefix with a period, but some files or folders I never want to see (and really wish I could just remove all together).

Sort files in multiple directories by date

This sorts files in multiple directories by their modification date. Note that sorting is done at the end using "sort", instead of using the "-ltr" options to "ls". This ensures correct results when sorting a large number of files, in which case "find" will call "ls" multiple times.

Find biggest 10 files in current and subdirectories and sort by file size
