change hash key name? 3

[al0]

Hi,

Is it possible to change a keyname in a hash? My keys values in the hash references to arrays. I have a option in my script where you can change the information in the hash.

chomp($hash{$matching_keys[$val]}[0]=<STDIN>);
chomp($hash{$matching_keys[$val]}[1]=<STDIN>);
chomp($hash{$matching_keys[$val]}[2]=<STDIN>);

After I have changed the values in the array inside my hash I want to change the keyname "$hash{$matching_keys[$val]" to something else.

You can't rename it, as such, but you can copy the value to another hash key and remove the first one, which has the same effect.

$hash{new_keyname = $hash{$matching_keys[$val]};
delete $hash{$matching_keys[$val]};

Thanks a lot, have been struggling with this for quite a bit of time.

You're welcome. Actually, there's a closing brace missing in the above code. Just to correct it, it should be:

$hash{new_keyname} = $hash{$matching_keys[$val]};
delete $hash{$matching_keys[$val]};
