Shell script execute multiple arguments at same time

I have  a shell script named "env_setup.sh" which takes in 2 arguments ,"server name" and property_file"

example of my shell invocation is this

$>env_setup.sh  server1  2.1-release.properties.

Open in new window


this script connects to the server and executes serveral tasks  including calling other scripts. This script takes 30 minutes to run start to finish.  As part of automation, the scrpt will be invoked by other script and server names passed in dynamically . I want this script to run the against servers simultaneously , not sequentially( because for e.g  30 mins  x 6 servers - 3 hrs).


is there a way I can ask pass in arguments to a wrapper script so that env_setup.sh is run simultaneously for several servers

i.e  
 env_setup.sh  server1  2.1-release.properties
 env_setup.sh  server2  2.1-release.properties
env_setup.sh  server3  2.1-release.properties
etc
etc

Just put an ampersand at the end if each line calling env_setup.sh. That puts the call into the background, without waiting for it to finish,  and moves on to the next line in the script.

So
env_setup.sh  server1  2.1-release.properties &
env_setup.sh  server2  2.1-release.properties &
