[jira] [Commented] (WHIRR-507) Make whirr script executable from
any path
[ https://issues.apache.org/jira/browse/WHIRR-507?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13204794#comment-13204794 ]
Tom White commented on WHIRR-507:
---------------------------------
This would be a good one to fix. Thanks for taking it on, Marco.
The readlink command isn't available on Mac, so we want to avoid using it. In Hadoop we're using BASH_SOURCE to resolve the script directory, so perhaps we could do the same here. See HADOOP-7089, and e.g. http://svn.apache.org/repos/asf/hadoop/common/trunk/hadoop-common-project/hadoop-common/src/main/bin/hadoop-daemon.sh

> Issue Type: Improvement
> Affects Versions: 0.7.0
> Environment: Linux (Ubuntu 11.04)

> I personally find very painful to be forced to call whirr script using its whole path. I'd prefer to add whirr script to my $PATH env variable so that I can call whirr from anywhere. I've modified the whirr script according to this purpose.
> I've created two version of the modified script:
> * one that uses the readlink command
> * one that doesn't used the former command.
> I only tested under Ubuntu 11.04 so I've no idea whether or not the readlink command is available on other distros. So please test and comment.
