- Synopsis:
- history [<number>]
- ! [<history number|history match>]
-
- Description:
- Command history is a useful little feature that allows you to
- quickly recall commands previously executed. The conventions
- followed are similar to those of the GNU bash or Cornell's tcsh Unix
- command shells. There are two versions of this command, one which
- just lists out the command history, and another which actually
- recalls a specific command for use on the input line.
-
- The HISTORY command is the simple version. All it does is spit out
- a list of commands you've previously entered (the exact number is
- determined by your HISTORY setting). You can limit the number of
- items to list, or just list all of them. Each item is assigned a
- unique index number, which can be referred to by !. This list can
- be saved for later use, if you have HISTORY_FILE set to something.
-
- The more complex version is the ! command. Based on the input you
- give it, it searches through your command history list and finds the
- first item that matches your query and puts it on the input line for
- immediate use. You can search based on a partial string (such as a
- command name, so search for the last use of it), or an index number.
-
- Examples:
- To list the 50 most recent items in your command history:
- /history 50
-
- To find the most recent use of the MSG command:
- /!/msg
-
- To use item 37 in your command history:
- /!37
