Korn shell timeout/kill script

Question

I am trying to write a simple Korn shell script to execute a loading process. The process occasionally runs into connectivity issues, so I need to kill it if it runs too long.

I have been trying the following code:

#!/usr/bin/ksh 
. /home/dw/script/load.ksh &
LOADPID=$!
sleep 100
kill $LOADPID

Unfortunately, the kill command does not kill the process - am I missing something?

Answer 1

Try kill -s HUP "$LOADPID". And if it still doesn't work, you could try kill -s KILL "$LOADPID".

Also note that it doesn't make sense to run the . command in background (that is in another process) as the whole point of the . command is to interpret the code in the given file in the current shell process.
