[Solved] Reverse the order of a list of file names (but not sort them alphabetically or numerically)

Hello all,
I have a list of file names in a text document where each file name consists of 4 letters and 3 numbers (for example MACR119). There are 48 file names in the document (they are not in alphabetical or numerical order). I would like to reorder the list of names so that the 48th name is 1st, the 47th name is 2nd, the 46th name is 3rd etc. There is no other text in the document, just the list of the names. Thank you in advance!

Try:
Code:
perl -0ne '$,="\n";print reverse split /\n/;print "\n"' file
