[SOLVED] get pid of launched bash file

Hi,

I've created a bash file that calls another bash. And I would like to get the pid from the second file launched, to wait for the file to ends. The second bash file launches processes in background. How can I get the PID from the second bash file?

Here's my code:

Code:

#!/bin/bash                                                                     

echo "FIRST"
./second.sh
PID=$(echo $!)
wait $PID
echo "CONTINUUING FIRST"

Maybe using the $$ built in variable?

Just my 2 cents...

But how can I get the PID from the launched second.sh in the first.sh script?

Just use pgrep to get the pid you want
Example PID=$(pgrep second.sh)
