Hello,
passing data / ( or sharing data, information ) between two
processes can be done
1. Writing the content in one file from 1st process and then reading
from second process.
you can do it, using simple text file or using seriallization.
2. Second way is through sockets. Once program writes in a socket and
the other program
reads from socket ( tcp Ip or any other protocol).
Please do understand that programs run in diffrent space and can
not use the memory space
of other.
Hope this helps
Cheers

Hello,
Is there a way to pass a variable from one program to another? I have a
web site that allows the user to set the time they would like to
download a file... The program uses the Linux "at" command and launches
another perl program that does the actual FTP download. I would like to
pass a parm variable (email address) from the web site, captured in the
first perl program to the second perl program. Is this possible?
First program uses this line to queue the job
system "/usr/bin/at $hour:$minute $tod today < /var/www/cgi-bin/images";
images is a text file containing the perl program that runs the FTP
download:
perl /var/www/cgi-bin/get_image_file.pl
Is there a way to pass a variable from program 1 to program 2?
Thanks for your help!!
