-----------------------------------------
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.
