Displays and manipulates the history of commands.

| description: |
The first form prints the history event list. If n is given, only n
most recent events are printed or saved. With -h, the history list is
printed without leading numbers. If -T is specified, timestamps are
printed also in comment form. (This can be used to produce files suitable for
loading with 'history -L' ). With -r, the order of printing
is most recent first, rather than oldest first. With -S, th second form saves the history list to filename. if 'savehist' shell variable is set to a number, at most that many lines are saved. With -L, the shell appends filename, which is presumably a history list saved by the -S option or the 'savehist' mechanism, to the history list. -M is like -L, but the contents of filename are merged into the history list and sorted by timestamp. In either case, 'histfile' is used if filename is not given and /.history is used if histfile is unset. If histlis is set, the first and second forms print and save the literal (unexpanded) form of the history list. The last form clears the history list. |
