Subject [jira] [Created] (KARAF-4566) "karaf" script invokes /bin/sh but requires /bin/bash functions

Alexis de Talhouët created KARAF-4566:
-----------------------------------------

             Summary:  "karaf" script invokes /bin/sh but requires /bin/bash functions
                 Key: KARAF-4566
                 URL: https://issues.apache.org/jira/browse/KARAF-4566
             Project: Karaf
          Issue Type: Bug
          Components: karaf-core
    Affects Versions: 3.0.6
         Environment: Solaris (SunOS solaris11.3 5.11 11.3 i86pc i386 i86pc)
            Reporter: Alexis de Talhouët


The bin/karaf script uses the "local" command which is a shell builtin of bash and similar
shells, but is not required for POSIX-compliance in sh. When I attempt to run karaf on a Solaris
system, I see the following output:

root@solaris:/opendaylight/bin# ./karaf
./karaf[172]: local: not found [No such file or directory]
./karaf[182]: local: not found [No such file or directory]
./karaf[183]: local: not found [No such file or directory]

Lines 172, 182 and 183 invoke "local" to make local variables to the function. According to
"man bash", this is a shell builtin. However, bin/karaf is invoked as:

#!/bin/sh

On most flavors of linux, this resolves to bash or dash which probably runs in a restricted
environment after checking to see that its $0 is sh. But on Solaris's /bin/sh is actually
ksh93 for backwards compatibility.

Since "local" is not part of a POSIX-compliant /bin/sh, depending on it in a script that is
invoked with /bin/sh is a bug.

(this explaination is borrowed from https://issues.apache.org/jira/browse/MNG-5852)
