%newHash = (%hash1, %hash2);

[blazar]

my %merge=(%hash1, %hash2); # ?
# how 'bout key clashes?
my %merge2=(%hash2, %hash1);
# will be different => MORE DETAILS - MORE DETAILS!!

PS: letting apart the fact that the question -if I understood it correctly- is extremely trivial and -still if I understood it correctly- I'd recommend reading some introductory perl document or tutorial before proceeding, I find that your "code" didn't help - to understand correctly your question. If you have some real (pseudo-)code that is suitable to illustrate a problem, then show it, else do not contribute to line noise: help people to help you!

jesuashok,

Did you Super Search this?

my %hash3 = (%hash1, %hash2);

Or even

@hash1{keys %hash2} = values %hash2;

However, if there are any common keys, the last value assigned will be retained.

can you please explain me the above code when you assigned the values of %hash2 to @hash1 how it is reflecting in %hash1

[Anonymous Monk]

There is no array "@hash1" there is only the hash "%hash1".

This is called a hash slice , and in a quirk of perl syntax uses the @ sigil instead of %

my %foo; @foo{ 'hash', 'slices' } = ( 'use', 'curly braces' );

my @bar; @bar[ 1,2,3,4 ] = ( 'array', 'slices', 'use', 'square brackets' );

Say it with me:

{ 'hashes', 'are', 'curly', 'ones' }

[ 'arrays', 'are', 'square' ]

( 'lists are round' )
