Check These Out

Show directories in the PATH, one per line
This version uses Pipes, but is easier for the common user to grasp... instead of using sed or some other more complicated method, it uses the tr command

find an unused unprivileged TCP port
Some commands (such as netcat) have a port option but how can you know which ports are unused?

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

Check disk for bad sectors
Checks HDD for bad sectors, just like scandisk or chkdisk under some other operating system ;-).

list files recursively by size

Find files containing string and open in vim
I often use "vim -p" to open in tabs rather than buffers.

Get your outgoing IP address
should be very consistent cause it's google :-)

Indent a one-liner.
Bash builtin type also indents the function.

Find the package a command belongs to on debian-based distros
Advanced revision to the command 8776 . This revision follows symbolic links. The quotation-marks surrounding $(which $1) allows for graceful handling of errors ( ie. readlink does not complain incase 'which' command generates (null) output)

Multiple variable assignments from command output in BASH
No command substitution but subshell redirection
