.TH LASTCOMM 1 "May 13, 2017"
.SH NAME
lastcomm \- display the last commands executed, in reverse order
.SH SYNOPSIS
.LP
.nf
\fBlastcomm\fR [\fB-f\fR \fIfile\fR] [\fB-x\fR] [\fIcommand-name\fR] ... [\fIuser-name\fR] ...
     [\fIterminal-name\fR] ...
.fi

.SH DESCRIPTION
.LP
The \fBlastcomm\fR command gives information on previously executed commands.
\fBlastcomm\fR with no arguments displays information about all the commands
recorded during the current accounting file's lifetime. If called with
arguments, \fBlastcomm\fR only displays accounting entries with a matching
\fIcommand-name\fR, \fIuser-name\fR, or \fIterminal-name\fR. If extended
process accounting is active (see \fBacctadm\fR(8)) and is recording the
appropriate data items, \fBlastcomm\fR attempts to take data from the current
extended process accounting file. If standard process accounting is active,
\fBlastcomm\fR takes data from the current standard accounting file (see
\fBacct\fR(2)).
.sp
.LP
If \fIterminal-name\fR is `\fB- -\fR', there was no controlling \fBTTY\fR for
the process. The process was probably executed during boot time. If
\fIterminal-name\fR is `\fB??\fR', the controlling \fBTTY\fR could not be
decoded into a printable name.
.sp
.LP
For each process entry, \fBlastcomm\fR displays the following items of
information:
.RS +4
.TP
.ie t \(bu
.el o
The command name under which the process was called.
.RE

have the following meanings:
.RS

.SH OPTIONS
.LP
The following options are supported:
.sp
.ne 2
.na
\fB\fB-f\fR \fIfile\fR\fR
.ad
.RS 11n
Uses \fIfile\fR as the source of accounting data. \fIfile\fR may be either an
extended process accounting file or a standard process accounting file.
.RE

.sp
.ne 2
.na
\fB\fB-x\fR\fR
.ad
.RS 11n
Uses the currently active extended process accounting file. If extended
processing accounting is inactive, no output will be produced.
.RE
