cat file every 30 seconds
is it possible to set a unix command to run every 30 seconds? i need to run the command:
cat filename every 30 seconds if possible. i've had a look through the manual and there doesnt seem to be anything there. It doesnt have to be cat, just anything that will show the contents of a file every 30s cheers.

Hi fitzjj,
you can use the sleep command to wait for a specified amount of time (in seconds). You could use this script f.e.: Code:
#!/bin/ksh
export INTERVAL=30
while [ true ]
do
cat filename
sleep ${INTERVAL}
done
You could adapt the loop to execute this during a specified time (f.e. every 30 seconds during 1 hour)... Hope this helps, Stef.
