Yes, I guess you've got the idea: using a hash is by far the fastest (and also easiest) method, provided the data will fit into memory, which we know to be the case.

Creating generic format file
by rajiyengar (Initiate) on Jan 02, 2014 at 02:29 UTC
    Thanks a lot. Now I want to take this to the next level. We get files from vendors in different format for a product and I want to transform them to one output format. Output file: Ocol1, Ocol2, Ocol3, Ocol4, Ocol5, Ocol6, Ocol7, Ocol8, Ocol9, Ocol10. Vendor files: Vendor1: Vcol1, Vcol2, Vcol3, Vcol4, Vcol5, Vcol6 Source-target mapping: Vcol1->Ocol1 Vcol3->Ocol2 Vcol4->Ocol4 Vcol5->Ocol8 Vendor2: Vcol1, Vcol2, Vcol3, Vcol4, Vcol5, Vcol6, Vcol12, Vcol15 Source-target mapping: Vcol1->Ocol12 Vcol3->Ocol2 Vcol4->Ocol15 Vcol5->Ocol8 I want to define input/output/source-target mapping in config files and want to write a generic perl program that reads the config files and generates output file. In the case of shell script, I can create config files and include them in my script. Would really appreciate some pointers here. Thanks a lot

      Hi,

      I'll try to understand and answer that question later, when I have more time, but I would suggest that you create a brand new post with your new question (possibly with a link to this thread), to get a chance that far more people can see your post and might answer it.
