LASTCOMM(1) NetBSD Reference Manual LASTCOMM(1)
NAME
lastcomm - show last commands executed in reverse order
SYNOPSIS
lastcomm [-f file] [command ...] [user ...] [terminal ...]
DESCRIPTION
lastcomm gives information on previously executed commands. With no ar-
guments, lastcomm prints information about all the commands recorded dur-
ing the current accounting file's lifetime.
Option:
-f file Read from file rather than the default accounting file.
If called with arguments, only accounting entries with a matching command
name, user name, or terminal name are printed. So, for example:
lastcomm a.out root ttyd0
would produce a listing of all the executions of commands named a.out by
user root on the terminal ttyd0.
For each process entry, the following are printed.
+ The name of the user who ran the process.
+ Flags, as accumulated by the accounting facilities in the sys-
tem.
+ The command name under which the process was called.
+ The amount of cpu time used by the process (in seconds).
+ The time the process started.
+ The elapsed time of the process.
The flags are encoded as follows: ``S'' indicates the command was execut-
ed by the super-user, ``F'' indicates the command ran after a fork, but
without a following exec(3), ``C'' indicates the command was run in
PDP-11 compatibility mode (VAX only), ``D'' indicates the command termi-
nated with the generation of a core file, and ``X'' indicates the command
was terminated with a signal.
