Does "some command" every 5 seconds.

Code:
while true
do
sleep 5
some command
done

You should not be creating an external wrapper to run a script every 5 seconds. The script itself should have an internal loop added.

Try this :

Code:
yes 'date;sleep 5' | ksh

The command 'date' is executed every 5 seconds ...

Code:
$ yes 'date;sleep 5' | ksh

^C$


The yes command as piped input to another command that requires an affirmative response before it completes the specified action.

The yes command outputs 'date;sleep 5'.
Ksh read end execute yes output.
Ye outputs 'date;sleep 5' again .....
