LASTCOMM(1)                              BSD General Commands 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 infor-mation information
     mation about all the commands recorded during 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
     ttyd_.

     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 system.
           •   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 executed by the super-user, ``F''
     indicates the command ran after a fork, but without a following exec, ``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.

FILES
     /var/account/acct  Default accounting file.
