In linux, use ctrl + r to quickly search for the history Command.

Linux command line history is a well-known but not commonly used command, because to check the number of a command, you need to enter history | grepxxx, and because !? Xxx ,! Xxx is neither running nor running, and ctrl + r is much more convenient. Ctrl + r purpose: reverse search for executed commands.

Ctrl + r
Purpose: reverse search for executed commands. (Reverse-I-search)

For existing history
611 ruby foo. rb
612 ruby bar. rb
613 ruby fo. rb
614 ruby ba. rb
615...
...
700...

Run ruby foo. rb without knowing the serial number.
1. ctrl + r
2. foo
Or
1. ctrl + r
2. fo
3. ctrl + r (continue reverse search)
Only a few keys are required. Of course, it would be more efficient if it was just a few commands or the [up] key.
