+== NAME
+
+last, lastb - show a listing of last logged in users
+
+== SYNOPSIS
+
+*last* [options] [_username_...] [_tty_...]
+
+*lastb* [options] [_username_...] [_tty_...]
+
+== DESCRIPTION
+
+*last* searches back through the _/var/log/wtmp_ file (or the file designated by the *-f* option) and displays a list of all users logged in (and out) since that file was created. One or more _usernames_ and/or _ttys_ can be given, in which case *last* will show only the entries matching those arguments. Names of _ttys_ can be abbreviated, thus *last 0* is the same as *last tty0*.
+
+When catching a *SIGINT* signal (generated by the interrupt key, usually control-C) or a *SIGQUIT* signal, *last* will show how far it has searched through the file; in the case of the *SIGINT* signal *last* will then terminate.
+
+The pseudo user *reboot* logs in each time the system is rebooted. Thus *last reboot* will show a log of all the reboots since the log file was created.
+
+*lastb* is the same as *last*, except that by default it shows a log of the _/var/log/btmp_ file, which contains all the bad login attempts.
+
+== OPTIONS
+
+*-a*, *--hostlast*::
+Display the hostname in the last column. Useful in combination with the *--dns* option.
+
+*-d*, *--dns*::
+For non-local logins, Linux stores not only the host name of the remote host, but its IP number as well. This option translates the IP number back into a hostname.
+
+*-f*, *--file* _file_::
+Tell *last* to use a specific _file_ instead of _/var/log/wtmp_. The *--file* option can be given multiple times, and all of the specified files will be processed.
+
+*-F*, *--fulltimes*::
+Print full login and logout times and dates.
+
+*-i*, *--ip*::
+Like *--dns ,* but displays the host's IP number instead of the name.
+
+**-**__number__; *-n*, *--limit* _number_::
+Tell *last* how many lines to show.
+
+*-p*, *--present* _time_::
+Display the users who were present at the specified time. This is like using the options *--since* and *--until* together with the same _time_.
+
+*-R*, *--nohostname*::
+Suppresses the display of the hostname field.
+
+*-s*, *--since* _time_::
+Display the state of logins since the specified _time_. This is useful, e.g., to easily determine who was logged in at a particular time. The option is often combined with *--until*.
+
+*-t*, *--until* _time_::
+Display the state of logins until the specified _time_.
+
+*--time-format* _format_::
+Define the output timestamp _format_ to be one of _notime_, _short_, _full_, or _iso_. The _notime_ variant will not print any timestamps at all, _short_ is the default, and _full_ is the same as the *--fulltimes* option. The _iso_ variant will display the timestamp in ISO-8601 format. The ISO format contains timezone information, making it preferable when printouts are investigated outside of the system.
+
+*-w*, *--fullnames*::
+Display full user names and domain names in the output.
+
+*-x*, *--system*::
+Display the system shutdown entries and run level changes.
+
+include::man-common/help-version.adoc[]
+
+== TIME FORMATS
+
+The options that take the _time_ argument understand the following formats:
+
+[cols=",",]
+|===
+|YYYYMMDDhhmmss |
+|YYYY-MM-DD hh:mm:ss |
+|YYYY-MM-DD hh:mm |(seconds will be set to 00)
+|YYYY-MM-DD |(time will be set to 00:00:00)
+|hh:mm:ss |(date will be set to today)
+|hh:mm |(date will be set to today, seconds to 00)
+|now |
+|yesterday |(time is set to 00:00:00)
+|today |(time is set to 00:00:00)
+|tomorrow |(time is set to 00:00:00)
+|+5min |
+|-5days |
+|===
+
+== FILES
+
+_/var/log/wtmp_,
+_/var/log/btmp_
+
+== NOTES
+
+The files _wtmp_ and _btmp_ might not be found. The system only logs information in these files if they are present. This is a local configuration issue. If you want the files to be used, they can be created with a simple *touch*(1) command (for example, *touch /var/log/wtmp*).
+
+An empty entry is a valid type of wtmp entry. It means that an empty file or file with zeros is not interpreted as an error.
