Call a UNIX script inside another and dont wait for it
Hi
I have two scripts script1.sh and script2.sh(say this script is a long running).
I want to call script2.sh inside and script1.sh,but when i call script2.sh i dont want to wait for script2 to complete and want this to run in back ground and go on next commands in script 1.sh and finally at the end want to check for script2 process ? I need the
  1. syntax to call script2 in script which doesnt wait and runs in back ground
  2. check for script 2 is complete at end of script 1

Would appreciate if someone can give a psuedo code for this

Thanks in advance
Matt

This is typically done like this:
content of script1:

Code:
/path/to/script2.sh &  # execute script2 in the background
other_commands
more_commands
wait                   # wait for all background processes to finish
last_commands

You can try:
Code:
#!/bin/sh
/script2.sh &
WAIT_PID=$!
# do other stuff
wait $WAIT_PID
