LAST(1)                     NetBSD Reference Manual                    LAST(1)

     last - indicate last logins of users and ttys

     last [-n] [-T] [-f file] [-H hostsize] [-h host] [-L linesize] [-N
          namesize] [-t tty] [user ...]

     last will list the sessions of specified users, ttys, and hosts, in re-
     verse time order.  Each line of output contains the user name, the tty
     from which the session was conducted, any hostname, the start and stop
     times for the session, and the duration of the session.  If the session
     is still continuing or was cut short by a crash or shutdown, last will so

     -n             Limits the report to n lines.

     -f file        last reads the file file instead of the default,
                    /var/log/wtmpx or /var/log/wtmp.  If the file ends with
                    `x', it is treated as a utmpx(5) format file, else it is
                    treated as a utmp(5) format file.

     -H hostsize    Use the provided hostsize as the width to format the host
                    name field.

     -h host        Host names may be names or internet numbers.

     -L linesize    Use the provided linesize as the width to format the tty

     -N namesize    Use the provided namesize as the width to format the login
                    name field.

     -T             Display better time information, including the year and

     -t tty         Specify the tty.  Tty names may be given fully or abbrevi-
                    ated, for example, ``last -t 03'' is equivalent to ``last
                    -t tty03''.

     If multiple arguments are given, the information which applies to any of
     the arguments is printed, e.g., ``last root -t console'' would list all
     of ``root's'' sessions as well as all sessions on the console terminal.
     If no users, hostnames, or terminals are specified, last prints a record
     of all logins and logouts.

     The pseudo-user reboot logs in at reboots of the system, thus ``last
     reboot'' will give an indication of mean time between reboot.

     If last is interrupted, it indicates to what date the search has pro-
     gressed.  If interrupted with a quit signal last indicates how far the
     search has progressed and then continues.

     /var/log/wtmp   login data base
     /var/log/wtmpx  login data base

     lastcomm(1), utmp(5), utmpx(5), ac(8)

     last appeared in 3.0BSD.
