.Dd September 18, 1996 .Dt LASTCOMM 1 .Os BSD 3 .Sh NAME .Nm lastcomm .Nd show last commands executed in reverse order .Sh SYNOPSIS .Nm lastcomm .Op Fl EScesu .Op Fl f Ar file .Op Ar command ... .Op Ar user ... .Op Ar terminal ... .Sh DESCRIPTION .Nm Lastcomm gives information on previously executed commands. With no arguments, .Nm lastcomm prints information about all the commands recorded during the current accounting file's lifetime.
p The following options are available:
p l -tag -width XXfXfileX -compact
p t Fl E Print the time the process exited. t Fl S Print the time the process started. t Fl c Print the amount of cpu time used by the process. t Fl e Print the amount of elapsed time used by the process. t Fl s Print the amount of system time used by the process. t Fl u Print the amount of user time used by the process. t Fl f Ar file Read from .Ar file rather than the default
p If no options are specified, .Fl cS is assumed. If .Nm is invoked with arguments, only accounting entries with a matching .Ar command name, .Ar user name, or .Ar terminal name are printed. For example:
p .Dl lastcomm a.out root ttyd0
p would produce a listing of all the executions of commands named
a a.out by user .Ar root on the terminal .Ar ttyd0 .
p For each process entry, the following are printed.
p l -bullet -offset indent -compact t The name of the user who ran the process. t Flags, as accumulated by the accounting facilities in the system. t The command name under which the process was called. t The amount of CPU
q Fl c , wall
q Fl e , system
q Fl s , or user
q Fl u time used by the process (in seconds). t The time the process started
q Fl S or exited
q Fl E . .El
p
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
.Xr exec ,
``C'' indicates the command was run in PDP-11 compatibility mode
(VAX only),
``D'' indicates the command terminated with the generation of a
a core file, and ``X'' indicates the command was terminated with a signal. .Sh FILES l -tag -width /var/account/acct -compact t Pa /var/account/acct Default accounting file. .El .Sh SEE ALSO .Xr last 1 , .Xr sigvec 2 , .Xr acct 5 , .Xr core 5 .Sh HISTORY The .Nm lastcomm command appeared in x 3.0 .
