running 2 command in same time 1

[paijo]

hi all,
I want to run my 3 scripts in one scripts, but the problem they will run in sequence of each line, it will run the 2 scripts after the first already finish runing and so is the 3rd script will be run after the 2nd finishing ?
is there any tips how to run all scripts not in sequence but I can run all in one single time only using one main scripts ?

for example.
mainscripts.
/etc/home/scripts1
/etc/home/scripts2
/etc/home/scripts3

I need run scripts1, scripts2 and scripts3 in one single time , not in sequence.


thanks a lot

Run the first two in background. Redirect stdout and stderr if required.

mainscripts.
/etc/home/scripts1 >script1.out 2>&1&
/etc/home/scripts2 >script2.out 2>&1&
/etc/home/scripts3

One more thing on the above:
If script3 finishes before script1 and script2, the first two may terminate early. This would happen if the user who calls "mainscripts" logs out.

If that is the case, start the first two scripts with the "nohup" command like this:

mainscripts.
/bin/nohup /etc/home/scripts1 >script1.out 2>&1&
/bin/nohup /etc/home/scripts2 >script2.out 2>&1&
/etc/home/scripts3

Another way to allow completion of the 3 scripts:
/etc/home/scripts1 >script1.out 2>&1 &
/etc/home/scripts2 >script2.out 2>&1 &
/etc/home/scripts3
wait

Hope This Helps, PH.
