leave -- remind you when you have to leave SYNOPSIS
leave [[+]hhmm] DESCRIPTION
leave waits until the specified time (within the next 12 hours), then reminds you that you have to leave by writing to the TTY that you exe- cuted leave on. You are reminded 5 minutes and 1 minute before the actual time, at the time, and every minute thereafter. When you log off, leave exits just before it would have printed the next message. OPTIONS
hhmm The time of day is in the form hhmm where hh is a time in hours (on a 12 or 24 hour clock), and mm are minutes. However, all times are converted to a 12 hour clock, and assumed to be in the next 12 hours. An attempt to set an alarm for farther into the future will be truncated to within the next 12 hours. + If the time is preceded by '+', the alarm will go off in hours and minutes from the current time. If no argument is given, leave prompts with "When do you have to leave?". A reply of newline causes leave to exit, otherwise the reply is assumed to be a time. This form is suitable for inclusion in a ~/.login or ~/.profile. SEE ALSO

The leave command appeared in 3.0BSD. BUGS
In the modern age with X(7) and window multiplexing programs like window(1) and screen(1), the leave command's reminders and admonitions might not be seen if the user has the window where leave was started minimized or obscured. This all begs for a more general user notifications system to be implemented. BSD

last -- indicate last logins of users and ttys SYNOPSIS
last [-swy] [-d [[CC]YY][MMDD]hhmm[.SS]] [-f file] [-h host] [-n maxrec] [-t tty] [user ...] DESCRIPTION
The 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 date and time. 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 following options are available: -d date Specify the snapshot date and time. All users logged in at the snapshot date and time will be reported. This may be used with the -f option to derive the results from stored utx.log files. When this argument is provided, all other options except for -f and -n are ignored. The argument should be in the form [[CC]YY][MMDD]hhmm[.SS] where each pair of letters represents the follow- ing: CC The first two digits of the year (the century). YY The second two digits of the year. If YY is specified, but CC is not, a value for YY between 69 and 99 results in a CC value of 19. Otherwise, a CC value of 20 is used. MM Month of the year, from 1 to 12. DD Day of the month, from 1 to 31. hh Hour of the day, from 0 to 23. mm Minute of the hour, from 0 to 59. SS Second of the minute, from 0 to 61. If the CC and YY letter pairs are not specified, the values default to the current year. If the SS letter pair is not specified, the value defaults to 0. -f file Read the file file instead of the default, /var/log/utx.log. -h host Host names may be names or internet numbers. -n maxrec Limit the report to maxrec lines. -s Report the duration of the login session in seconds, instead of the default days, hours and minutes. -t tty Specify the tty. Tty names may be given fully or abbreviated, for example, ``last -t 03'' is equivalent to ``last -t tty03''. -w Widen the duration field to show seconds, as well as the default days, hours and minutes. -y Report the year in the session start time. If multiple arguments are given, and a snapshot time is not specified, 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

A last utility appeared in 3.0BSD. BUGS
If a login shell should terminate abnormally for some reason, it is likely that a logout record will not be written to the utx.log file. In this case, last will indicate the logout time as "shutdown". BSD
