Linux enters the history command in the shell

In the Linux shell, often input commands have a lot of similarities, even the same, if the long command, the efficiency is really very low, but can be through ctl+r, find the history of the previous input commands, it is very useful.

After pressing Ctrl+r, enter some key commands, which are searched by fuzzy query.

Like the SCP I used.

After pressing the shortcut key (reverse-i-search) ' SCP ': [email protected]*.*.*.*:/home/dongjunjie/*.gz./

can come out. Very convenient
