Method:!$

ALT +.

ESC +.

Two of the following methods, terminal will be automatically filled

3. Use the part of the previous command except for the last parameter

4. Use any part of the previous command

Method: ALT + +.

Where Num represents the first of the previous command, starting at 0 for LS-SHLD Hello.txt. ALT +0+. is LS. 1 is-shld.

5. Replace one part of the previous command

Method: replace Foo with bar

^foo^bar replaces only one

!!:gs/foo/bar Replaces all

Method:!!

MORE: We often run a lot of very long commands, this time, you can view the command through the history, and then use! (Command number in history).
