LASTCOMM(1)                OpenBSD 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
     arguments, lastcomm prints information about all the commands recorded
     during the current accounting file's lifetime.

     The options are as follows:

     -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:

           o   Name of the user who ran the process.
           o   Flags, as accumulated by the system's accounting facilities.
           o   Command name under which the process was called.
           o   Amount of CPU time used by the process (in seconds).
           o   Time the process started.
           o   Elapsed time of the process.

     The flags are encoded as follows: `S' indicates the command was executed
     by the superuser, `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 terminated with
     the generation of a core file, and `X' indicates the command was
     terminated with a signal.
