Shell Programming and Scripting

Hello All,

I would like to know if it is possible to launch a job in background for infinite time.

example:

myScript.ksh
while true
do
( echo "(`date`)"; top -U user | grep 'Memory:' ) >> log &
sleep 1800
done

and when i do myScript.ksh & my log file is just updated for the first time and never again.

but when i do myScript.ksh it works kool.

could someone suggests me pls

tnx

Are you executing in background and then logging out? If so, try:

Code:

nohup myScript.ksh &

Regards.

No, iam leaving my session open.

Infact i just wanted to check the resources at certain time during weekdays.

Well, that's a strange behaviour, then...
Why don't you schedule it in a cron job?

Code:

00,30 * * * * myScript.sh > /dev/null 2>&1

And remove the while loop inside the script, of course
Regards.

the worst thing is that i am not admin. if i want to do that i have to request the sys admin and its big process flow ( request on homologation + tests + manager approval + request for prod).

i dont want go through the hectic process for this simple pgm.

will try to find another way.

tnx a lot

regards.

I see... Well, try anyway the "nohup" solution, just in case, becasue your script seems to be OK.
Regards.
