comment Is there a reason not to run bash as root?
@ghoppe explain the different md5sums. And the fact that running set -o vi turns off tab completion when run under sh, but not bash. Saying sh is bash ignores the fact that they behave differently, which is the point of this question. Why is OS X using sh, and is it unsafe to change it use bash. I don't doubt that they are both built from the same source, but they are not the same.

According to stat -f "%N: %i" /bin/sh /bin/bash, they aren't hardlinks of each other and an md5sum of the two files produces different checksums. Even if /bin/sh were a symlink or hardlink to /bin/bash, Bash checks the name it was run under and activates a compatibility mode if the name is sh.

@sleske Ah, good news, I saw that it was a web app and stopped looking. I will have to give it another look.

Good idea, but I am not guaranteed a network connection. I have changed the question to reflect this requirement.

I have started playing with S5, specifically Pod::S5 (search.cpan.org/dist/Pod-S5/S5.pm). It looks fairly nice, but I none of the default themes are to my liking and I don't really want to spend the time hacking up a CSS file to make it look nice. Right now it is my fall back position.

comment What does export do in BASH?
Can you point to any documentation to that affect. I am looking for more information than that. For instance, does a variable only need to be exported once, or do you need to export it after every change, etc.

@Dennis Williamson, yes, you are correct, that is a typo.

That is an odd decision because they are documented to behave differently (number all lines vs number blank lines). If -n were documented to "number lines" without the word "all", I would agree with the code. Hmm, but looking at the BSD manpage it says "Number the output lines, starting at 1", so this is really just a problem with GNU cat's documentation.
