.SH DESCRIPTION
|
|
|
|
|
.PP
|
|
|
|
|
.I Last
|
|
|
|
|
Searches backward through the login administration file (default is
|
|
|
|
|
\fI/usr/adm/wtmp\fR), printing information about previous logins and
|
|
|
|
|
reboots.
|
|
|
|
|
During a long search, the SIGQUIT signal (CTRL-\\) causes \fIlast\fR to
|
|
|
|
|
display how far back it has gone; it then continues.
|
