Shell Programming and Scripting

Hey,

So I have a shell script that outputs some variables, call them $a and $b. I know in shell scripting if I wanted to use the variables in another shell script I'd do

Code:

sh code.sh "$a" "$b"

How can I do something similar with perl?

A shell script can print variables, name and value or just values
or if dotted in the same shell (sourced) can set (exported or not) variable values to the environment of the current shell, since that is what runs the script, not a child shell process.

A PERL program can print the variables so a wrapper, parent shell can capture and export them "export `perl_prog.pl`"
or can call a shell or shell script as a child (`shell_script.sh`, system(), popen()), which will inherit the PERL environment, with any environment changes PERL made (How do I set environment variables in Perl programs? | Perl ENV array | alvinalexander.com).

If I understand your question, This is a real simple example:

Code:

$ cat p1.pl
#!/usr/bin/perl -w
# Script:  p1.pl
print "I am p1.pl\n";
my $v1  =  "param1";
my $v2  =  "param2";
system( "perl p2.pl $v1 $v2" );

$ cat p2.pl
#!/usr/bin/perl -w
# Script:  p2.pl
print "I am p2.pl, with: $ARGV[0], $ARGV[1]\n";


$ p1.pl
I am p1.pl
I am p2.pl, with: param1, param2
