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, ``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.
