default hpux posix shell doenst work but ksh does on orace weblogic script

p7 — Thu, 03 Jul 2014 14:24:41 GMT

hi all,

a customer is trying to setup oracle weblogic on hpux 11.31. hes trying to run a reports.sh script with the default /bin/sh but it keeps having problems assigning variables. when he runs it as a ksh it works.

oracle support also ran it on a similiar hpux box they have and it worked. the customer doesnt really want to run ksh, he d

rather run the default hpux shell.

has anyone ever run into something similiar?

thx in advance

The script is missing the interpreter line: #!/usr/bin/ksh

The shell you use to login will be the default for scripts that do not specify the intended interpreter. That's why I consider the interpreter mandatory for all shell scripts. For about 95% of the features in the POSIX shell, ksh is a match, but there are differences, just like there are differences between bash and ksh. All 3 are considered to be 'POSIX' compliant but shell script writers are not often aware of the differences, thus the problems.

So keep your standard /usr/bin/sh or /sbin/sh POSIX shell and just add the interpreter line to the WebLogic script.

thx for the quick reply,

here is the top of the script, isnt that ok?

## Example file to set environment variables in Bourne-shell or K-shell
## for Oracle Reports 10gR2. Refer to Install Doc for more detail on each
## of these environment variables. You need to modify some of the environment
## variables before doing source on this file ( % . reports.sh ).

Yes, #!/bin/sh is the interpreter line and it specifies the POSIX shell (/bin/sh points to /usr/bin/sh).

So change it to #!/usr/bin/ksh and the script should work fine.
