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
     ttyd0.

     For each process entry, the following are printed.

           oo   The name of the user who ran the process.
           oo   Flags, as accumulated by the accounting facilities in the system.
           oo   The command name under which the process was called.
           oo   The amount of cpu time used by the process (in seconds).
           oo   The time the process started.
           oo   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.

SEE ALSO
     last(1), sigaction(2), acct(5), core(5)
