sharing a variable across two scripts.

[rajendra]

Hello All,

I have two scripts A and B .Script A calls script B for getting data. This
data is used by script A for processing. Is there a concept of shared
variable so that data stored in this shared variable can be accessed by
script A.


With Rgds,
Raj

Hello ,
Thanks for the reply.
To be more specific, I would like to know whether a perl variable(may be a
variable or array or a hash) which can be shared across two different batch
files.

I'm guessing you are looking for sharing data between separate processes.

I do not know if there is a Perl module for shared memory but any other IPC
method is available as a module on CPAN.

In general, no. Threads share memory visibility easily, but separate
processes do not. There are several different methods of moving data
between processes. Interprocess communication (IPC).

Write data to a file, read from the other process.
Open a network socket between the processes.
Use SYSV shared memory if supported by the OS.
