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 $LOADPID
Unfortunately, the kill command does not kill the process - am I missing something?
Try kill -s HUP "$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.
. /some/script & does have a few uses: the script is executed by the same interpreter, and inherits shell parameters, functions, etc. However none of this is happening in this specific example.
