Linux Command Line Most Used Shortcuts

Just sharing some of the command line shortcuts that I used and learnt; please share yours also.

1. To search in history or run previous commands
This is my most used shortcut. Hit Control-R and begin to type a string.

For example, type the following and hit Enter.

grep root /etc/passwd

Then hit Control-R and begin to type 'grep'.

Control-R
(reverse-i-search)`gre': grep root /etc/passwd

When you see the original command listed, hit Enter to execute it. Alternatively, you can also hit the Right-Arrow to edit the command before running it.


Use -> ctrl + r and type the command, to go one more level back again hit ctrl + r, to edit the command before you execute use right key arrow.

2. To clear the present screen use -> ctrl + l (My discovery works on board also).

3. To edit previous command using vi commands -> set -o vi

Now you can use the Vi cw command to change the word in command.

4. Use of alias

alias ll='ls -l'
alias gohome='cd; ls'
If you want these custom aliases should be available each login, add them to your .bashrc.

You can refer to command line Bible got by chancehttp://blog.taragana.com/wp-content/uploads/2009/01/linux-command-line.jpg
