Date: Thu, 20 Jul 1995 23:02:54 +0200 From: Wolfram Schneider <w@cs.tu-berlin.de> To: current@freebsd.org, wosch@cs.tu-berlin.de Subject: New options for lastcomm(1) Message-ID: <199507202102.XAA03168@localhost.cs.tu-berlin.de>
next in thread | raw e-mail | index | archive | help
Example:
$ lastcomm -e kermit
kermit -FX w ttyp2 366.50 es
>From the manpage:
lastcomm [-EScesu] [-f file] [command ...] [user ...] [terminal ...]
The following options are available:
-E The time the process exited.
-S The time the process started, default.
-c The amount of cpu time used by the process (in seconds), de-
fault.
-e The amount of elapsed time used by the process (in seconds).
-s The amount of system time used by the process (in seconds).
-u The amount of user time used by the process (in seconds).
Use [-cS] as default if no one of these previous options called.
