The TeX Live source tree is really huge. Is there an overview somehow somewhere of the meaning of all those file extensions? I mean e.g. in texlive/Master/texmf, there are 10 .sty, 18 .enc, 21 .tcx, 22 .map, 23 .tlu, 35 .cfg, 366 .asy and 425 .xdy files. I have no clue what kind of files these are.
All in all there are almost 1000 (!) different file extensions :-O http://sprunge.us/KDJh 1)
What do they all mean?
What list is 1) ?
texlive/Master$ # a command is run in the TeX Live tree's root directory find ... # finds all files in this directory, omits the bin directory... | sed . # filters out everything except the filenames extensions | sort # sorts the list lexically | uniq -c # counts the number of duplicates of each line | sort -nr # sorts the resulting "list of counts" numerically reverse
-> The result is a list of file extensions ordered by their frequencies
