I would like to run a system process in the background. The system process redirects output to a file. Immediatly after that process completes, I want to run a perl function that will check for a particular string in the output file.

I am running 4 such things simultaneously. 

system 1, ( "some process 1" );
system 1, ( "some process 2" );
system 1, ( "some process 3" );
system 1, ( "some process 4" );

But immediatly after each of the above process completes, I want to run my perl error checking function. Please suggest how I can run that.

I was thinking I might be able to do something like: 

system 1, ( "some process 1; perl checkerror.pl" );
system 1, ( "some process 2; perl checkerror.pl" );
system 1, ( "some process 3; perl checkerror.pl" );
system 1, ( "some process 4; perl checkerror.pl" );

I have made the checkerror a function, so I don't want to make it a perl script all by itself. Any advice?

Also, is there a way I can know when all the 4 processes have completed?

Thanks
