Do you know how to obtain such a shell in Debian? I have dash for sh, and it knows both commands -v and $(). And I have no idea how to get more simple one. Do you have one? Do you know the way how to check if shell is pre-POSIX and just disable the check in this case. Or can you offer some another check that will satisfy you as a potential user of pre-POSIX shell? The check that will somehow report that ctags _executable_ file is missing. > If etags is not installed, the current script prints > > xargs: etags: No such file or directory make_ctags prints xargs: ctags: No such file or directory sort: cannot read: tags: No such file or directory For me it is not good enough error message, it says it can't find some ctags| etags file. But says nothing that is is an utility, that is missing... So I would try to find better way to report that ctags utility is missing. PS Vitus, I added you to CC, because I know that you are quite good in bash scripting, may be you would give some good ideas I do not have.
