We have migrated from a unix solaris server to a linux server. When we run the same pieces of code, they are behaving very differently. Some of the problems I am facing are -
cat filename | read var1 var2
echo "var1 var2"
works in unix, but returns null values in linux.
interesting.... what do you on Solaris?
First, echo have
where you probably meant:
besides the above, this will not return anything as you're PIPING to 'read' which creates a subshell which exits after the 'read' is done and your var1/var2 vanish as well.

Your $PATH env var probably does not include the directory where 'compress' resides on linux (if it's installed at all).

struct::compare
Compare(3pm) User Contributed Perl Documentation Compare(3pm)NAME
Struct::Compare - Recursive diff for perl structures.
SYNOPSIS
use Struct::Compare;
my $is_different = compare($ref1, $ref2);
DESCRIPTION
Compares two values of any type and structure and returns true if they are the same. It does a deep comparison of the structures, so a hash
of a hash of a whatever will be compared correctly.
This is especially useful for writing unit tests for your modules!
PUBLIC FUNCTIONS
o $bool = compare($var1, $var2)
Recursively compares $var1 to $var2, returning false if either structure is different than the other at any point. If both are
undefined, it returns true as well, because that is considered equal.
BUGS /NEEDED ENHANCEMENTS
o blessed references
compare currently does not deal with blessed references. I need to look into how to deal with this.
