The problem with this options is that it is ... long. Even its minimum abbreviation is 5 characters long. Now, during the last year, I got three requests for adding support of new compression programs to tar, and each of them asked for a new short option! Clearly, I was not able to satisfy that (except in one case, when I gave up and assigned -J for lzma compression). Of course, each of them got a long option. In my opinion and in the opinion of Antonio, having a convenient short option for that purpose will solve the problem once and for all. Then, if a `xyz' compressor arrives, it will suffice to add a corresponding entry to the table of compressors and not bother about assigning any new long option for it. Instead, one will simply use -I xyz, or whatever another short letter from the 6 available ones, if there is strong opposition against -I. > In my opinion short option names should be only used for options that are > compatible with other vendors' tar programs. I understand your concern about compatibility. However, the -I option seems to be incompatible in itself: the BSD tar uses it as a synonim for -T, in star it means `do interactive creation/extraction/renaming', etc. Regards, Sergey
