last(C)                         19 June 1992                         last(C)


 Name

    last - indicate last logins of users and teletypes

 Syntax

    last [ -h ] [ -n limit ] [ -t tty ] [ -w wtmpfile ] [ name ]

 Description

    The last command checks the wtmp file, which records all logins and
    logouts for information about a user, a tty line or any group of users
    and lines.  Arguments specify a user name and/or tty.

       last -t 01 root

    would list all root sessions as well as all sessions on /dev/tty01.  last
    prints the sessions of the specified users and ttys, including login
    name, the line used, the device name, the process ID, plus start time and
    elapsed time.

    last with no arguments prints a record of all logins and logouts, in
    reverse chronological order.

    The options behave as follows:

    -h          no header.

    -n limit    limits the report to n lines.

    -t line     specifies the tty.

    -w wtmpfile uses wtmpfile instead of /etc/wtmp.  Note that this file must
                have the same format as /etc/wtmp.

 File

    /etc/wtmp       login database
