LASTLOGIN(8) System Manager's Manual LASTLOGIN(8)
lastlogin -- indicate last login time of users
lastlogin [-nrt] [-f filename] [-H hostsize] [-L linesize] [-N namesize]
lastlogin will list the last login session of specified users, or for all
users by default. Each line of output contains the user name, the tty
from which the session was conducted, any hostname, and the start time
for the session.
If multiple users are given, the session information for each user is
printed in the order given on the command line. Otherwise, information
for all users is printed, sorted by uid.
lastlogin differs from last(1) in that it only prints information
regarding the very last login session. The last login database is never
turned over or deleted in standard usage.
The following options are available:
Process input from filename. If the file ends with an ``x'',
then it is assumed that it is a lastlogx(5) file, else it is
assumed to be a lastlog(5) file.
Set the field width for host output to hostlen characters.
Set the field width for line output to linelen characters.
Set the field width for name output to namelen characters.
-n Attempt to print numeric host addresses. This option is only
supported with lastlogx(5) format files.
-r Reverse the order of the sort.
-t Sort by last login time (most recent first.)
/var/log/lastlogx default last login database
/var/log/lastlog compatibility last login database
lastlogin looks by default to the /var/log/lastlogx database, where some
old programs that are not utmpx(5) aware might only write to
/var/log/lastlog. To look at the old database one can use:
lastlogin -f /var/log/lastlog
last(1), lastlog(5), lastlogx(5), ac(8)
John M. Vinopal wrote this program in January 1996 and contributed it to
the NetBSD project.
