in reply to How to combine multiple files together

I would check out the 'join' utility. If you have two files, A and B, comma-delimited, they are -sorted- (see the sort utility), and you want all lines that have the first column in common, then:
join -j 1 -t ',' A B
This ought to work fine! Then just iterate across all of the files, iterating as suits you best.

    This is almost good, however I do not want repeated lines. so if file B has multiple instances of Column 1 of file A, I want it just simply printed continuously, no line breaks. However I will still have to stick to Perl, because this will be an adon to a another script.
