GNU/Linux shells have many shortcut keys which you can use to speed up your work, below is a rough list of some (also see CTRL-R the history section of the commands, over here, Section 4.2).
The CTRL-D the "end-of-file" (EOF) key combination can be used to quickly log out of any terminal. CTRL-D is also used in programs such as "at"
to signal that you have finished typing your commands (the EOF command).
The CTRL-Z key combination is used to stop a process. It can be used to put something in the background temporarily.
For example, if you were editing a file with vim or emacs just press CTRL-Z to regain control of the terminal do what you want and then type fg to bring it back. For
further information please see Section 9.3.
||If fg doesn't work
If fg doesn't work you may need to type jobs and then fg job_name or fg job_number
The CTRL-A and CTRL-E key combinations are used for going to the start and end of the line on the command
line. Use CTRL-A to jump to the start of the line, and CTRL-E to jump to the end of the line.
The CTRL-K key combination can be used to cut or delete what is currently in front of the cursor.
The CTRL-Y key combination can be used to paste the last thing you deleted (using CTRL-K or CTRL-W ).
The CTRL-W key combination can be used to cut or delete the entire line that has being typed.
