Remount root in read-write mode.
Saved my day, when my harddrive got stuck in read-only mode.

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

Creates a 'path' command that always prints the full path to any file
The command creates an alias called 'path', so it's useful to add it to your .profile or .bash_profile. The path command then prints the full path of any file, directory, or list of files given. Soft links will be resolved to their true location. This is especially useful if you use scp often to copy files across systems. Now rather then using pwd to get a directory, and then doing a separate cut and paste to get a file's name, you can just type 'path file' and get the full path in one operation.

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"

Clone perms and owner group from one file to another
Copy both perms and owner group from one file to another.

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

Find partition name using mount point
lsblk | grep mountpoint

In (any) vi, add a keystroke to format the current paragraph.
That goes into your $HOME/.exrc file. " Nice macro to reformat lines: map ^A !}fmt Note that the ^A has to be input by typing ^V^A.

move you up one directory quickly
Alias a single character 'b' to move to parent directory. Put it into your .bashrc or .profile file. Using "cd .." is one of the most repetitive sequence of characters you'll in the command line. Bring it down to two keys 'b' and 'enter'. It stands for "back" Also useful to have multiple: alias b='cd ../' alias bb='cd ../../' alias bbb='cd ../../../' alias bbbb='cd ../../../../'

Replace duplicate files by hardlinks
