Run script 3 times and then stop it.

[ojosVerdes]

I have a script that I want to run 3 times (every 20 minutes) then stop it.

I understand how the sleep command works; but I am not sure what looping contruct to use.

I dont want to use a crontab job cause don't have specific times to run it.

TIA.

how about running it 3 times without any loop constructs at all:

script
sleep 20
script
sleep 20
script

got u.
How would you run it then if the sleep 1200 is inside the scrip?

I probably would try copying the script 3 times to a new file, then editing the new file to add the sleep 20s, and would pull the sleep 1200 at the same time. Ed Fair

If your running a Redhat Linux box you can put it in the crontab and use "*/20" where you would put the time. */20 says "run every 20 minutes." Meekness: Uncommon patience in planning a revenge that is worth while.

alternative: cut thin ia file called what-ever-ypu-want.sh
-------------

/bin/sh
case ${SLEEP:=$1} in [1-9]*[0-9]);; *) SLEEP=1;; esac

## a, b and c are dummy flags to repeat 3 times the job
## you also could define a counter !!

for x in a b c
do
copy your scripts here
sleep $SLEEP
done
