Subject [jira] [Commented] (ACCUMULO-2423) Converge Shell scripts on single implementation
Date Mon, 03 Mar 2014 15:47:24 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2423?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13918175#comment-13918175

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.

> 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.
