pretend to be busy in office to enjoy a cup of coffee
Create a progress dialog with custom title and text using zenity.

Get all IPs via ifconfig
Fetches the IPs and ONLY the IPs from ifconfig. Simplest, shortest, cleanest. Perl is too good to be true... (P.S.: credit should go to Peteris Krumins at catonmat.net)

Provide the ten largest subfolders in the current folder

Get ethX mac addresses
I much prefer using /sbin/ip over /sbin/ifconfig for most everything. I find the interface and output to be much more consistent and it has many abilities that ifconfig, route, etc. do not. To get the mac address for only one interface, add 'show dev [interface]' to the 'ip link' part of the command: ip link show dev eth0 | grep 'link/ether' | awk '{print $2}' . Also, both this command and the ifconfig one do not require root access to run, so the sudo is not necessary.

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"

Batch rename extension of all files in a folder, in the example from .txt to .md

Find the package that installed a command

connect to X login screen via vnc
the $15 may change for you depending on your distro, etc...

check open ports without netstat or lsof

Look for English words in /dev/urandom
Little faster alternative.
