passing an array to another perl script and update

shrawansher has asked for the wisdom of the Perl Monks concerning the following question:

i have a perl that executes variable number of processes and stores the log files after each process..Depending on the scenario, there can be multiple log files.The script looks for certain error codes in all the log files and store them in an array.My question is is there any way to pass the array to another perl script as an argument while updating it after each file ? Basically what i am trying to achieve is to get the last updated error list and when the script runs the currently updated error list so that i can print the difference being the errors in the files formed currently.

I don't get why you make it separate scripts, I'd just let one script both scan for errors and do something with that list. Otherwise, you'll have to serialize the array to pass it to the other script. Traditionally there are a few approaches: if they're typically all a single word, just pass them along the command line. Or you could pipe the array, one item per text line, into the second script. Or if all that fails, dump it in a serialized format (flat text file, CSV, JSON, XML, Data::Dumper, or Storable) and and pass that, either by pipe or in a file of which you pass the filename, to the second script.

You should store the codes in a file, and pass the path of that file as an argument, see @ARGV , Getopt::Long	[reply]

Have you considered using subroutines instead of different entire perl scripts?	[reply]
