NAME

     last -- indicate last logins of users and ttys

SYNOPSIS

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

DESCRIPTION

     last will list the sessions of specified users, ttys, and hosts, in reverse 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 ses-
     sion is still continuing or was cut short by a crash or shutdown, last will so indicate.

     The following options are available:

     -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.  If the file is ``-'', standard input is used.

     -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 field.

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

     -n 	    Print host addresses numerically.  This option works only on wtmpx(5) entries, and prints nothing on wtmp(5) entries.

     -T 	    Display better time information, including the year and seconds.

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

     -x 	    Assume that the file given is in wtmpx(5) format, even if the filename does not end with an 'x'.  Also useful when reading
		    such format from standard input.

     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 progressed.  If interrupted with a quit signal last indicates how far the
     search has progressed and then continues.

NAME

       last - display login and logout information about users and terminals

SYNOPSIS

       last [-a] [-n number | -number] [-f filename]
	    [name | tty]...

DESCRIPTION

       The  last  command looks in the /var/adm/wtmpx file, which records all logins and logouts, for information about a user, a terminal, or any
       group of users and terminals. Arguments specify names of users or terminals of interest. If multiple arguments are given,  the  information
       applicable  to any of the arguments is printed. For example, last root console lists all of root's sessions, as well as all sessions on the
       console terminal. last displays the sessions of the specified users and terminals, most recent first, indicating the  times  at	which  the
       session	began,	the  duration of the session, and the terminal on which the session took place. last also indicates whether the session is
       continuing or was cut short by a reboot.

       The pseudo-user reboot logs in when the system is shutdown and when it reboots. Thus,

	 last reboot

       gives an approximate record of when the operating system instance was shutdown and when it rebooted. This can  be  used	to  calculate  the
       availability of the operating system over time.

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

       If last is interrupted, it indicates how far the search has progressed in /var/adm/wtmpx. If interrupted with a quit signal (generated by a
       CTRL-), last indicates how far the search has progressed, and then continues the search.

OPTIONS

       The following options are supported:

       -a			Displays the hostname in the last column.

       -f filename		Uses filename as the name of the accounting file instead of /var/adm/wtmpx.

       -n number|-number	Limits the number of entries displayed to that specified by number.  These  options  are  identical;  the  -number
				option is provided as a transition tool only and is removed in future releases.

ENVIRONMENT VARIABLES

       Date and time format is based on locale specified by the LC_ALL, LC_TIME, or LANG environments, in that order of priority.

FILES

       /var/adm/wtmpx	 accounting file
