Automating a perl script by another perl script
Hi, I have a perl script which prompts user for certain inputs. I want to automate this by creating a separate script which runs the above perl file and probably passing the inputs in a separate text file. Can anybody give me some pointers or how to do this ?

Re: Automating a perl script by another perl script
How about this thought? perl -e 'print while()' /etc/passwd This would print the content in /etc/passwd file. Here I just use shell's symbol to pass the file's content to perl script. -Original Message- From: Nath, Alok (STSD) [EMAIL PROTECTED] Sent: Mar 13, 2007 8:41 PM To: beginners@perl.org Subject: Automating a perl script by another perl script Hi, I have a perl script which prompts user for certain inputs.

snip
The open function can start a program and feed it data (like popen in C):
open my $fh, '|perl other.pl' or die $!;
open my $in, '', 'args';
while ($in) {
print $fh $_;
}
If you need more control or bi-directional communication you should
use IPC::Open2 (stdin and stdout) or IPC::Open3 (stdin, stdout, and
stderr). Both are part of core Perl, so you should already have them
installed.
