[jira] [Commented] (KAFKA-4566) Can't Symlink to Kafka bins

["Jim Jagielski (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-4566?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16032048#comment-16032048 ] 

Jim Jagielski commented on KAFKA-4566:
--------------------------------------

Since this is a shell, we can check which OS we are on, and if OS X, macOS or even a BSD, we can use perl:

bq. perl -MCwd=abs_path -le 'print abs_path shift;'

e.g.:

bq. "$(dirname "$(perl -MCwd=abs_path -le 'print abs_path shift;' "$0")")"

> in the kafka consumer for example, the last line is :
> https://github.com/apache/kafka/blob/trunk/bin/kafka-console-consumer.sh#L21
> {code}
> exec $(dirname $0)/kafka-run-class.sh kafka.tools.ConsoleConsumer "$@"
> {code}
> if I create a symlink using 
> {code}
> ln -s
> {code}
> it doesn't resolve the right directory name because of $(dirname $0) 
> I believe the right way is to do:
> {code}
> "$(dirname "$(readlink -e "$0")")"
> {code}
>  
> Any thoughts on that before I do a PR?
