Top Forums Shell Programming and Scripting How to schedule my script without crontab Post 302323591 by Phi01 on Monday 8th of June 2009 11:37:34 AM

Very Interesting Command, i never came by this before. But can you correct me on this if i'm wrong.

The "at command" does not have an every day feature, so away around this is by having it invoke itself in a script.


# my.daily runs every day
at now tomorrow < my.daily
daily-processing

So here, my.daily is a script that is written like this
Code:
at now tomorrow

Then when the user runs there script and in the parameters they have the keyword "tomorrow"
So this insures tomorrow is always recurring.

so an example of this would be:

Code:
$ at 1145am now tomorrow < my.daily
at> cc -o foo foo.c
at> ^D

Did i get this right?

Thanks.

NAME
calendar - reminder service SYNOPSIS
calendar [ - ] DESCRIPTION
Calendar consults the file `calendar' in the current directory and prints out lines that contain today's or tomorrow's date anywhere in the line. Most reasonable month-day dates such as `Dec. 7,' `december 7,' `12/7,' etc., are recognized, but not `7 December' or `7/12'. On weekends `tomorrow' extends through Monday. When an argument is present, calendar does its job for every user who has a file `calendar' in his login directory and sends him any posi- tive results by mail(1). Normally this is done daily in the wee hours under control of cron(8). FILES
calendar /usr/lib/calendar to figure out today's and tomorrow's dates /etc/passwd /tmp/cal* egrep, sed, mail subprocesses SEE ALSO
at(1), cron(8), mail(1) BUGS
Your calendar must be public information for you to get reminder service. Calendar's extended idea of `tomorrow' doesn't account for holidays. CALENDAR(1)
