Check These Out

Find the files that contain a certain term
Simple use of find and grep to recursively search a directory for files that contain a certain term.

Kick user

Save a file you edited in vim without the needed permissions (no echo)
Write a file you edited in Vim but that you do not have the permissions to write to (unless you use sudo.) Same as #1204 but without the echo to stdout that I find annoying.

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"

stop windows update
Windows only: stops windows update and the nagging restart window. You need your admin password for this one.

check open ports without netstat or lsof

Print all fields in a file/output from field N to the end of the line

recursively change file name from uppercase to lowercase (or viceversa)
or, to process a single directory: $ for f in *; do mv $f `echo $f |tr '[:upper:]' '[:lower:]'`; done

Combine cssh and shell expansion to execute commands on a large cluster
This will open an awful lot of little windows, but is quite useful if you want to quickly patch something on a cluster of servers.

Calculate days on which Friday the 13th occurs (inspired from the work of the user justsomeguy)
Friday is the 5th day of the week, monday is the 1st. Output may be affected by locale.
