Killed by signal 15.

Hi all

I have Master script, Main script ,and 4 Child script.

Master.sh

#!/bin/bash
/export/home/user/Main.sh

Main.sh

#!/bin/bash
/export/home/user/Child1.sh &
/export/home/user/Child2.sh &
/export/home/user/Child3.sh &
/export/home/user/Child4.sh &

I run only Master.sh script because Master.sh calls Main.sh and Main.sh calls 4 Child.sh (need run parallel)
After I ran Master.sh,I get message "Killed by signal 15."
I'm not sure that root cause is input "&" ?

please suggest me how to do this?

Thanks

There shouldn't be any issue on using '&'
Could you tell us what Child1.sh Child2.sh does?
