Dear All
I am trying to run the script below, but I always get the following error:
[EMAIL PROTECTED] scripts]$ secondperl
Global symbol "$greeting" requires explicit package name at /home/paulus/scripts/secondperl line 6.
Global symbol "$greeting" requires explicit package name at /home/paulus/scripts/secondperl line 7.
Execution of /home/paulus/scripts/secondperl aborted due to compilation errors.
Easy enough.
The script is:
#!/usr/bin/perl use warnings; use strict;
Above, you are asking Perl to make you play by the Good Programmer rules. One of those rules is, you must declare a variable before using it.
$greeting = "World";
Here you use an undeclared variable. Usually, you'll declare a variable with "my", so change to above line to:
my $greeting = 'World';
Hope that helps.

print "It matches\n" if "Hello World" =~ /$greeting/;
