Re^2: Get random unique lines from file

I like your solution and ours are similar. You know more about the FASTA format than me and were able to "decode" the OP'S intent better than me. I like it!

I do admit confusion about this "// 10", I don't understand why that would be necessary? Or what the purpose is?

for ( @seqPosns[ 0 .. $ARGV[ 1 ] // 10 ] ) {
...blah....}

It simply means that if I forget/omit the second parameter (the number of output records to produce), I get 10 by default. With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". In the absence of evidence, opinion is indistinguishable from prejudice. The start of some sanity?	[reply]
