Bill Havanki commented on ACCUMULO-2423:
----------------------------------------
I much prefer bash over sh.
bash 3 is certainly an acceptable minimum. Like Christopher said, bash 4 isn't
shipped with Mac OS X ... [even Mavericks is still on
3.2|http://apple.stackexchange.com/questions/100915/what-version-of-bash-comes-with-osx-10-9-mavericks].
However, it's easy to get it via [Homebrew|http://brew.sh] or
[MacPorts|http://macports.org] so it's not that unreasonable to require it
there.

> Project: Accumulo
> Issue Type: Improvement
> Affects Versions: 1.6.0
> Reporter: Mike Drob
>
> Do we want to have a stated dependency on a particular shell? Most of our
> scripts explicitly use bash, but some use sh. Most scripts invoke
> {{#\!/usr/bin/env bash}} but some do {{#\!/bin/bash}} or other crazy things.
> I don't have a particular preference which way we go, but I'd like to see us
> standardize one way or the other.
> If we use {{/bin/sh}}, then we can run everything through the
> [checkbashisms|https://wiki.ubuntu.com/DashAsBinSh#I_am_a_developer._How_can_I_avoid_this_problem_in_future.3F]
> script (also available for other distros)
> If we go the other way, and switch everything to bash, then we can run them
> through {{ksh -n}} for deprecation warnings. I know that's a different shell,
> but they're still moderately useful.
