| How would you write to those 2 hashes???

I'm not quite sure what you mean by this. You can update the value
at a certain key at anytime by simply assigning something to it like
$hash1{2} = 'foobar';
This sets hash1's value at key '2' to 'foobar'.
Or am I misunderstanding your question?

| | Hi,
| |
| | can any one point me at how to compare two hases.
| |
| | ie
| |
| | hash1
| | 1 abc
| | 2 def
| | 3 ghi
| |
| | hash2
| | 1 abc
| | 2 defzzz
| | 3 ghi
| |
| | I want to take the values for matching keys and see if
| they are the same if
| | not write out the value
| |
| | so in the above the values in 1 and 1 are ok, the values
| in 3 and 3 are ok
| | but in key 2 they do not match
| |
| `-------------------------------------------------
|
| This should do it:
|
| foreach my $key ( keys(%hash1) ) {
|
| if( $hash1{$key} ne $hash2{$key} ) {
| print "hash1: $hash1{$key} hash2: $hash2{$key}\n";
| }
|
| }
|
