history — Display a command history list
Format
Description
history [first[last]]
tcsh shell:
history [-hTr] [n]
history -S|-L|-M [filename]
history -c
history is an alias for fc –l. Like fc –l, history displays the list of commands that
have been input to an interactive shell. This command does not edit or reenter the
commands. If you omit last, history displays all commands from the one indicated
by first through to the previous command entered. If you omit both first and last with
this command, the default command range is the 16 most recently entered
commands.
See “fc — Process a command history list” on page 272 for more information.

the n most recent events are printed or saved.
Note: See “tcsh — Invoke a C shell” on page 626 for descriptions of the tcsh shell
variables and commands indicated below.
The tcsh shell history built-in command uses the following options:
v With -h, the history list is printed without leading numbers.
