Using foreach with two lists
Hi everybody,

I'm trying to use a foreach command with two lists. The file.txt looks like this:
Code:
var1: 100 200 300
var2: 3 6 9

I'm trying to use a foreach command to associate the two variables together. My script looks like this:
Code:
#! /bin/tcsh 

set a=(`cat file.txt | grep 'var1' | cut -d ':' -f2`)
set b=(`cat file.txt | grep 'var2' | cut -d ':' -f2`)

foreach f (${a}) 
foreach b (${b})

echo "var1 = " $a
echo "var2 = " $b

end
end

My output at the moment is:
Code:
var1 =  100
var2 =  3
var1 =  100
var2 =  6
var1 =  100
var2 =  9
var1 =  200
var2 =  6
var1 =  300
var2 =  9

What I want the output to be is:
Code:
var1 =  100
var2 =  3
var1 =  200
var2 =  6
var1 =  300
var2 =  9

Does anybody know how I can do this? I think it should be pretty simple but I'm useless at this!

Thanks in advance

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.
