Final answer:
To repeat a command without using the arrow keys, use the history command and specify the command number.
Step-by-step explanation:
To repeat the command used five commands ago without using the arrow keys, you can use the history command in the shell. Here are the steps:
Type history and press Enter. This will display a list of previously executed commands.
Identify the command number that corresponds to the command you want to repeat. Note that the command numbers are listed on the left side.
Type ! and press Enter. Replace with the actual number of the desired command.
For example, if the command you want to repeat is number 10, you would type !10 and press Enter. The shell will execute the command again.
To make the shell repeat the command that was used five commands ago without using the arrow keys, you can use the following command:
!!-5
This command utilizes the event designator feature of the shell, specifically Bash. The exclamation mark (!) recalls the command history, and the -5 specifies the 5th command before the current command. This is a feature of the command history substitution in shells like Bash or Zsh that allows quickly referencing previous commands.
