scheduling a job using at command

Shell Programming and Scripting

Hi All,

I've been trying to schedule a job using the at command on Solaris 5.10 but i've been running into some issue. ( Not allowed to use cron :wall: )

I have a script that reads a logs file, does some iteration and cat's the output in an email .

## the o/p of /home/myscript.sh is : 

Hello world.

i need to run this script every day at 9:00 AM and i read up on at and saw some examples on the internet and came up with the below :

cat /home/myscript.sh 

...
...
...

echo /home/myscript.sh | at now tomorrow

basically, i embedded the at job in the script, so when i run the script manually it schedules another job for tomorrow and the loop continues.
I've also checked the atq and i can see the job scheduled for tomorrow.

the problem is when i checked this morning , i see no email and i checked the log which the script outputs to and it never ran .

can some one point out where i went wrong. (FYI i also tried the my.daily and recursive scheduling but at doesnt like

at -f /home/myscript.sh now tomorrow < my.daily

error: at bad time specification

In at, now means at this time today. Specifying now and tomorrow gives conflicting specifications for when the job should be run. If you want to run a job every day at about noon, you can start it off some morning by saying:

at -f /home/myscript.sh noon < my.daily

and use the command:

at -f /home/myscript.sh noon tomorrow < my.daily

in myscript.sh to have it schedule itself to run again the next day.
