UNIX Command Line Cheatsheet

Handy commands

Navigating the command line

• ctrl-k : Delete everything to the right
• ctrl-w : Delete the previous word
• ESC-b : Go back one word
• ESC-f : Go forward one word

Aliases and Functions

Add aliases and functions should be added to /.bash_rc

To activate added aliases use:

. ~/.bash_rc

alias ss="./script/server"
alias tu='top -o cpu' #cpu sorted
