Find usb device
I often use it to find recently added ou removed device, or using find in /dev, or anything similar. Just run the command, plug the device, and wait to see him and only him

tar+pbzip2 a dir

grep for minus (-) sign
Use flag "--" to stop switch parsing

Collect a lot of icons from /usr/share/icons (may overwrite some, and complain a bit)
Today I needed to choose an icon for an app. My simpler way: put all of /usr/share/icons in myicons folder and brows'em with nautilus. Then rm -r 'ed the entire dir.

Show directories in the PATH, one per line
The output of "echo $PATH" is hard to read, this is much easier. The parentheses ensure that the change to the input field separator (IFS) only happens the the sub shell and not affecting the current shell.

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

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"

get you public ip address
Relies on ifconfig.me functioning. It's about as easy as it gets, and memorable to old geeks too.

List just the executable files (or directories) in current directory
A bit shorter ;)

Check which modules your PHP is using
