LAST(1)                 NetBSD General Commands Manual                 LAST(1)

last -- indicate last logins of users and ttys
last [-n] [-nTx] [-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 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 session is still continuing or was cut short by a crash or shutdown, last will so indicate. -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 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 abbrevi- ated, for example, ``last -t 03'' is equivalent to ``last -t tty03''. -x Assume that the file given is wtmpx(5) format, even if the filename does not end with an `x'. 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.
