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. FILES

NAME
last - indicate last logins of users and teletypes SYNOPSIS
last [ -f filename ] [ -N ] [ name ... ] [ tty ... ] DESCRIPTION
Last will look back in the wtmp file which records all logins and logouts for information about a user, a teletype or any group of users and teletypes. Arguments specify names of users or teletypes of interest. Names of teletypes may be given fully or abbreviated. For example `last 0' is the same as `last tty0'. If multiple arguments are given, the information which applies to any of the arguments is printed. For example `last root console' would list all of "root's" sessions as well as all sessions on the console terminal. Last will print the sessions of the specified users and teletypes, most recent first, indicating the times at which the session began, the duration of the session, and the teletype which the session took place on. If the session is still continuing or was cut short by a reboot, last so indicates. The pseudo-user reboot logs in at reboots of the system, thus last reboot will give an indication of mean time between reboot. Last with no arguments prints a record of all logins and logouts, in reverse order. The -f filename option allows the user to examine an alternate wtmp file. The -N option limits the report to N lines. If last is interrupted, it indicates how far the search has progressed in wtmp. If interrupted with a quit signal (generated by a con- trol-) last indicates how far the search has progressed so far, and the search continues. FILES
