LASTCOMM(1)                          BSD                           LASTCOMM(1)



NAME
     lastcomm - show last commands executed in reverse order

SYNOPSIS
     lastcomm [ command ] ... [username] ... [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.  If called with arguments,
     lastcomm prints only accounting entries with a matching command name,
     username, or terminal name.  For example,

          lastcomm a.out root ttyd0

     produces a listing of all the executions of commands named a.out by user
     root on the terminal ttyd0.

     For each process entry, lastcomm prints the following:
          The name of the user who ran the process
          Flags, as accumulated by the accounting facilities in the system
          The command name under which the process was called
          The amount of CPU time (in seconds) the process used
          The time the process exited

     The flags are encoded as follows: S indicates the command was executed by
     the super-user, F indicates command ran after a fork, but without a
     following exec, D indicates the command terminated with a stack dump, and
     X indicates the command was terminated with a signal.
