# Command Line Recall Once you punch in a command, it gets saved in your shell's history list. This list persists in your current shell session until you call it quits. After you exit, the list gets saved to a history file, ready for a rerun in your next session. If you dig up an old command in a subsequent shell session, you can always give it a tweak in the same fashion we saw earlier. ## ## The history Command To view your history list, use the **history** command. Enter the command without any additional options, or optionally followed by a number, to list that many of the most recent commands. For example: ``` history 8 382 date 383 ls /usr/bin | sort -a | more 384 man sort 385 cd /usr/local/bin 386 man more 387 useradd -m /home/chris -u 101 chris 388 passwd chris 389 history 8 ``` As you can see from the output, a number precedes each command line in the list. You can recall one of those commands using an exclamation point (!), followed by the number that correlates against your desired command: ``` !382 ``` Alternatively, to simply repeat the most recent command, you can enter the following: ``` !! ``` Keep in mind that when an exclamation point is used, the command runs blind without presenting an opportunity to confirm the command you’re referencing... --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
