6 methods of executing historical commands in linux bash

Many times when we use the Linux command line, we need to find the used commands.

At this time, you usually like to use the up and down arrow keys or the history command to find the previously used command.

In this article, I’d like to share with you some quick search history command methods that you don’t know.

6 methods of executing historical commands

• !!
  repeat the previous command
• !t
  repeat the previous command headed by t
• !Number
  repeat the previous command with number in the history table
• !-Number
  repeat the history table countdown number command
• !$
  gets the last option in the previous command
• Ctrl + R
  use Ctrl + R to enter the history search mode to query a past command in the history table. After finding the command to be repeated, press enter to execute the command
