Dmitry Sivachenko commented on HADOOP-10797:
--------------------------------------------
Debian is not the only system around.
/bin/sh is a standard location for bourne shell.
FreeBSD, for instance, installs bash as "/usr/local/bin/bash". That is why I
propose to either use "/bin/sh" and do not rely on bash extensions in scripts,
use good old Bourne shell syntax, or use "/usr/bin/env bash", which will invoke
bash in a portable way and work on both debian and FreeBSD.
> Hardcoded path to "bash" is not portable

> Key: HADOOP-10797
> URL: https://issues.apache.org/jira/browse/HADOOP-10797
> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 2.4.1
> Reporter: Dmitry Sivachenko
> Attachments: bash.patch
>
>
> Most of shell scripts use shebang ling in the following format:
> #!/usr/bin/env bash
> But some scripts contain hardcoded "/bin/bash" which is not portable.
> Please use #!/usr/bin/env bash instead for portability.
> PS: it would be much better to switch to standard Bourne Shell /bin/sh, do
> these scripts really need bash?
