Hello,
Alan wrote me about the following issue. I don't know anything about bash/sh issues (except that sh is indeed more likely to be present and that I had to change many occurencies of /bin/sh to /bin/bash on garden because /bin/sh was a symlink to dash which didn't work). Does anyone object the change from bash to sh?
Dear Alan,
at the same time a question for you: do you also experience any issues with ./do-all.sh and other scripts in "build the latest binaries"? I just checked and they start with #!/usr/bin/env bash How does that compare? (I agree that it probably makes sense to do the change, I just wanted to hear from others and maybe I need to find a good reference to what is not allowed in sh that works in bash.)
On mac it is:
sh --version
GNU bash, version 3.2.48(1)-release (x86_64-apple-darwin10.0)

This is one solution that would probably work (if bash is present, but, again, it is not by default on many systems). Another would be to write clean shell scripts, whenever possible, that do not rely on bash-isms, and would work everywhere, even with dash: "DASH is a POSIX-compliant implementation of /bin/sh that aims to be as small as possible. It does this without sacrificing speed where possible. In fact, it is significantly faster than bash (the GNU Bourne-Again SHell) for most tasks." This should not be much of a constraint.
