Ivan Kelly updated ZOOKEEPER-722:
---------------------------------
Attachment: (was: zk-722.diff)
> zkServer.sh uses sh's builtin echo on BSD, behaves incorrectly.
> ---------------------------------------------------------------
>
> Key: ZOOKEEPER-722
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-722
> Project: Zookeeper
> Issue Type: Bug
> Components: scripts
> Environment: Mac OS X
> Reporter: Ivan Kelly
> Priority: Minor
> Attachments: zk-722.diff
>
>
> zkServer.sh output the PID of the zookeeper process with:
> echo -n $! > "$ZOOPIDFILE"
> This uses -n which sh's builtin echo does not support. From echo's manpage.
> <snip>
> Some shells may provide a builtin echo command which is similar or
> identical to this utility. Most notably, the builtin echo in sh(1) does not
> accept
> the -n option. Consult the builtin(1) manual page.
> </snip>
> This means that echo -n PID > ZOOPIDFILE will mean the contents of ZOOPIDFILE
> will be "-n PID". This stops zkServer.sh stop from working correctly.
