Dt LEAVE 1
Os
Sh NAME
Nm leave
Nd remind you when you have to leave
Sh SYNOPSIS
Nm
Sm off
Oo
Op Cm \&+
Ns Ar hhmm
Oc
Sm on
Sh DESCRIPTION
Nm
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
executed
Nm
on.
Pp
You are reminded 5 minutes and 1 minute before the actual
time, at the time, and every minute thereafter.
When you log off,
Nm
exits just before it would have
printed the next message.
Sh OPTIONS
Bl -tag -width flag
It Ar hhmm
The time of day is in the form
Ar hhmm
where
Ar hh
is a time in
hours (on a 12 or 24 hour clock), and
Ar mm
are minutes.
Pp
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.
It Cm \&+
If the time is preceded by
Ql Cm \&+ ,
the alarm will go off in hours and minutes
from the current time.
El
Pp
If no argument is given,
Nm
prompts with "When do you have to leave?".
A reply of newline causes
Nm
to exit,
otherwise the reply is assumed to be a time.
This form is suitable for inclusion in a
Pa ~/.login
or
Pa ~/.profile .
Sh SEE ALSO
Xr calendar 1 ,
Xr csh 1 ,
Xr sh 1
Sh HISTORY
The
Nm
command appeared in
Bx 3.0 .
Sh BUGS
In the modern age with
Xr X 7
and window multiplexing programs like
Xr tmux 1
and
Xr screen 1 ,
the
Nm
command's reminders and admonitions might not be seen if the user
has the window where
Nm
was started minimized or obscured.
Pp
This all begs for a more general user notifications system to be implemented.
