last — indicate
last logins of users, ttys, and hosts
last utility will either list the
sessions of specified users,
ttys, and hosts, in reverse time
order, or list the users logged in at a specified snapshot date and time 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.
The options are as follows:
-foption to derive the results from stored wtmp files. When this argument is provided, all other options except for
-nare ignored. The argument should be in the form “[[[CC]YY]MMDD]hhmm[.SS]” where each pair of letters represents the following:
All but the “hh” and “mm” letter pairs are optional. If the “CC” and “YY” letter pairs are not specified, the values default to the current year. If the “MM” and “DD” letter pairs are not specified, the values default to the current month and day. If the “SS” letter pair is not specified, the value defaults to 0.
lastreads the file file instead of the default, /var/log/wtmp.
-number is also supported, but is deprecated.
last -t 03is equivalent to
last -t tty03.
If multiple arguments are given, and a snapshot time is not
specified, the information which applies to any of the arguments is printed,
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
last reboot will give an indication of
mean time between reboot.
