Get the Nth argument of the last command in $HISTFILE

This gets the Nth argument in the last line of your history file. This is useful where history is being written after each command, and you want to use arguments from the previous command in the current command, such as when doing copies/moving directories etc. I wrote this after getting irritated with having to continually type in long paths/arguments. You could also use $_ if all you want is the last argument. Show Sample Output

Oneliner to run commands on multiple servers

Oneliner to run commands on multiple servers over ssh. - First parameter "$1" is the command you want to execute remotely. ( It can be multiple commands e.g. "hostname;uptime") - Second parameter "${@:2}" represents the remote host/s you want to run the command/s on.

Fast command-line directory browsing

After typing cd directory [enter] ls [enter] so many times, I figured I'd try to make it into a function. I was surprised how smoothly I was able to integrate it into my work on the command line. Just use cdls as you would cd. It will automatically list the directory contents after you cd into the directory. To make the command always available, add it to your .bashrc file. Not quite monumental, but still pretty convenient.

Copy the contents of one partition to another

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"

list block devices

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

Job Control

You're running a script, command, whatever.. You don't expect it to take long, now 5pm has rolled around and you're ready to go home... Wait, it's still running... You forgot to nohup it before running it... Suspend it, send it to the background, then disown it... The ouput wont go anywhere, but at least the command will still run...
