Shell Programming and Scripting

cat test.ksh

Code:

#!/usr/bin/ksh

VAR="Dear Friends \n How are you? \n Have a nice day \n"
export VAR
echo "Inside test.ksh";
./test.pl

cat test.pl

Code:

#!/usr/bin/perl

print "Inside test.pl \n";
print "$VAR";

Output:

Code:

./test.ksh
Inside test.ksh
Inside test.pl

What I want to achieve is, I have a string variable (with blank spaces) in ksh. When I echo that string variable in ksh, it prints fine. BUT, I have a scenario where I would want the perl script to be able to use that string variable. How can I achieve that?

Ok, I myself got it after few tests. Here is how I do it:

Instead of print "$VAR"; I use print $ENV{"VAR"};

Thanks!

Having exported it from your your Shell script, within the Perl, invoked from same script you will find that print "$ENV{VAR}\n" is what you want. Export exports a variable into the environment and the %ENV hash is how Perl accesses them. Regards Neil
