Re^2: conditional calling of script from other script

1. i want my script1.pl to be executed any number of times. by executing the command # perl $PATH/script1.pl -qx . when this is executed for first time i will then execute script2.pl .now when i execute my script script1.pl second time or more number of times from same command as above. 2. i have to use some external factor to see if the script2.pl needs to be executed but i am unable to decide and that the main i am asking you all. i think this may give you some good idea of what i am asking.

First of all, to answer your question directly, just have script1 check for the existence of a particular file; if that file doesn't exist, create it and run script2: `my $LOCKFILE = 'script1.lock'; if (!-e $LOCKFILE) { open FH, ">$LOCKFILE" or die $!; close FH; system("perl script2.pl"); }` [download] However, if they're both perl scripts, it seems silly to do a fork and invoke another perl interpreter to run it. Can't you just use or require it and call whatever function(s) you need directly? -b	[reply] [d/l]
