Jean-Baptiste Onofré commented on KARAF-5304:
---------------------------------------------
Let me check but AFAIR, {{ps -p}} (instead of {{ps p}}) should work on AIX.
> checkRootInstance function in karaf script fails under AIX

> Key: KARAF-5304
> URL: https://issues.apache.org/jira/browse/KARAF-5304
> Project: Karaf
> Issue Type: Bug
> Affects Versions: 4.0.9
> Environment: AIX 6.1, 7.1, 7.2
> Reporter: Christian Brüssow
> Assignee: Jean-Baptiste Onofré
> Fix For: 4.2.0, 4.0.10, 4.1.3
>
>
> Calling e.g. the status script under KARAF_HOME on AIX, the subsequent called
> script "karaf" fails and prints the following to stdout:
> {quote}
> [...]
> Usage: ps [-AMNZaedfklm] [-n namelist] [-F Format] [-o specifier[=header],...]
> [-p proclist][-G|-g grouplist] [-t termlist] [-U|-u userlist]
> [-c classlist] [ -T pid] [ -L pidlist ]
> [-@ [wparname] ]
> Usage: ps [aceglnsuvwxX] [t tty] [processnumber]
> [...]
> {quote}
> The error is triggered by the function checkRootInstance() in the script
> "karaf". The function uses the following code to determine the status of the
> karaf process:
> {quote}
> [...]
> if ps p "$\{ROOT_INSTANCE_PID\}" > /dev/null
> then
> [...]
> {quote}
> Under a standard AIX installation the command ps does not allow "p" as an
> argument. So this call will always fail.
