How can I call one Perl script from another?

10 comments

If you would like to make a call to, or reference, a Perl script from within a different Perl script, you can accomplish this a system(), exec() or the backtick operator to the path for Perl. For example:

system("/usr/bin/perl /path/to/my_script.pl ");

Or store output to array:

@myarray = `/usr/bin/perl mysecondperlscript.pl`;

So maybe an AI Perlmind — an artificial intelligence written in Perl — could rewrite its own code with improvements and enhancements, then call the new version of itself by the methods described in this weblog.

If i’m not mistaken you mean batch file under NT/XP use system command
system(â€œc:\path\to\my.cmdâ€);

use system command.

ex: calling_script.pl
/usr/bin/perl -w

printf(“%s\n”,”this is calling script”);

system(“/myhome/caller_script.pl”);
exit;

Hi, I am calling 1.pl from main.pl file.
using
#main.pl
system (“perl 1.pl”);

In this case it works fine. But when I am doing

#main.pl
system (“perl 1.pl”);
system (“perl 2.pl”);

then it doesn’t executes “1.pl” properly.
So I would like to know, is there any constraint for this? Do I need to take any precautions for this?

Thanks,

How can I call a sister perl script inside a perl script using Expect.pm. When the perl expect ends the script exits never executing the other script even though my last line in the script is

@myarray=`/usr/bin/perl /myscript.pl`;
print $myarray;

Hi,
I want to write into file by calling another perl/cgi script.
sample1.cgi

#!/usr/bin/perl
print "Content-type: text/html\n\n";
use CGI;
use Switch;
print qq'
Field Name :
';

from sample1.cgi I m trying to call sample2.pl

sample2.pl

#!/usr/bin/perl
print "Content-type: text/html\n\n";
use CGI;
use Switch;
my $field="AVATAR";
open NEW_FILE,">/tmp/test.dat";
print NEW_FILE "$field";
close NEW_FILE;

When I m executing sample2.pl this works fine, This is able to write a word “AVATAR” into file but when I m using sampe1.cgi I doesn’t work as same.

How can I call one Perl script from another?
