Message: [QUOTE="martin, post: 4814158"] Hi , this question deals with a perl script that calls other perl scripts using 'exec' or 'system' call. I think it is a mute point and of no concern but I decided to ask just to be sure. Bascially I have something like this : Calling script file ---> #!/usr/bin/perl ..... ..... ..... my $cdpat2 = 'C:\Program Files'; my $cdpat1 = 'C:\DIR1 my $cdpat3 = 'C:\DIR2\STUFF\bin'; exec ("CalledScript1.pl $cdpath1 $cdpath2 $cdpath3"); exec ("CalledScript2.pl $cdpath1 $cdpath2 $cdpath3"); The question I have is that, do I need to worry about the completion of the first script, i.e. Called Scriopts1.pl before I involve the CalledScript2.pl. I don't think this should be of a concern, but I thought to ask since the first call could take a long while to process and the second one relies on the completion of the first one. Thanks.
