To reissue and repeat a long command without retyping it on a Unix or Linux system, you can use the history and ! commands.
The history command displays a list of the most recently executed commands in the current shell. Each command is preceded by a number, which is called the command's "history number".
To repeat a command, you can use the ! command followed by the history number of the command you want to repeat.
For example, to repeat the most recently executed command, you can use the following command:
!-1Sourcwww:e.lautturi.com
To repeat the second-most recently executed command, you can use the following command:
!-2
You can also use the ! command followed by the first few characters of the command you want to repeat. For example, to repeat the last command that started with the characters mysql, you can use the following command:
!mysql
This will repeat the last command that started with the characters mysql.
