             Summary: start.sh fails in realpath function under Solaris 10
                 Key: KARAF-5190
                 URL: https://issues.apache.org/jira/browse/KARAF-5190
             Project: Karaf
          Issue Type: Bug
    Affects Versions: 4.0.9
         Environment: SunOS 5.10 (aka Solaris 10) SPARC, awk from /usr/bin
            Reporter: Christian Brüssow


Trying to start Apache Karaf 4.0.9 under Solaris 10 (SPARC) the start-script exits with a syntax error:

/opt/test/karaf/bin/start: syntax error at line 22: `LINK=$' unexpected

I have investigated this and found, the script relies on a feature the standard awk for this plattform does not support - at least on our machine. The -F"-> " paramter will only use the dash "-" as the field separator. When using the XPG4 version of awk the script works.

Examples on the command line:

With XPG4 awk:
$ ls -l "$(basename ".bashrc")" | /usr/xpg4/bin/awk -F"-> " '{print $2}'

$ 

Empty output, which is fine as the file used is no link.


With the standard awk:
$ ls -l "$(basename ".bashrc")" | /usr/bin/awk -F"-> " '{print $2}'
rw
$

The "rw" is returned, because only the "-" is used as a seperator to split "ls -l" .bashrc, which looks like "-rw-r--r--   1 devel    other        392 Jun 30  2015 .bashrc" in this case.


Sadly, under Solaris, one should not presume the awk in the PATH is a GNU or nawk. Some adminstrator will also not include the XPG4 "bin"-directory at the beginning of the PATH. So the script itfself must handle this.
