`my %merge=(%hash1, %hash2); # ? # how 'bout key clashes? my %merge2=(%hash2, %hash1); # will be different => MORE DETAILS - MORE DETAILS!!` [download] 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!	[reply] [d/l]

Or even `@hash1{keys %hash2} = values %hash2;` [download] However, if there are any common keys, the last value assigned will be retained. -QM -- Quantum Mechanics: The dreams stuff is made of	[reply] [d/l]

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

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' )	[reply]
