NAME
lastlogin
- indicate last login time of users
SYNOPSIS
lastlogin
[-nrt]
[-f filename]
[-H hostsize]
[-L linesize]
[-N namesize]
[user ...]
DESCRIPTION
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:
- -f filename
-
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.
- -H hostlen
-
Set the field width for host output to
hostlen
characters.
- -L linelen
-
Set the field width for line output to
linelen
characters.
- -N namelen
-
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.)
FILES
/var/log/lastlogx

EXAMPLES
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
