.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.
