Killing the Wrong Background Process

BASH on Solaris

Hi All,

I posted a problem whereby I was looking to Kill a background (calling Send)mail) process after a certain time had elapsed.

A User Scottn very kindly provided a useful function to do this as below


CheckAndKill()
{

sleep "$EMAIL_TIMEOUT_THEN_KILL"
[ "$(ps | awk '$1 == '$1)" ] && echo "Killing process $1" && kill -9 "$1"

}

Howvere I am calling this in the wrong way as below:

send_email "Warning Notification" $warning_msg" | tee -a "$LOG_PATH"/email_output.lst &
CheckAndKill $! &

When I check the shell output I can see that I am killing the wrong process ie I am killing the "tee" not the actual send_email function.

The $! passed into CheckAndKill() is clearly picking on the process id of the tee and not the send_email function
Any ideas how to correctly kill the send_email function?

Kind Regards
Satnam
