    Is it possible to execute Perl script within another script?

    Hello friends,

    I don't have any Idea with PERL programming. Actually I use to work with perl program execution so my question is may be simple but I am not good at writing the code. What I want to ask is it possible to call a perl script from within another script? I want to call a perl script into another please let me know if it is possible? Is it possible to execute it?

    Thanks in advance.

    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:

    Code:
    system("/usr/bin/perl /path/to/my_script.pl ");
    Or store output to array:

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

    Try this:

    add.pl

    Code:
    my $sum = qx(perl addition.pl 10 -20); ## Remove double quotes from your code
    print "Result is $sum";
    addition.pl

    Code:
    $x, $y) = @ARGV;
    
    if ( !defined($x) ) {
       print STDERR"usage add <x> <y>\n";
       exit;
    }
    else
    {
    $n = 0;
    $n = $x + $y;
    }
    
    print $n;
