Another case of Badly placed parens.

Another case of Badly placed parens.
The shell error message "Badly placed ()'s" can occur for a surprisingly simple oversight. If the script begins with a shell-invocation comment, but is missing the exclamation-point, it is simply a comment and not an invocation. If you attempt to execute it from a shell other than the shell you intended to invoke, you could get this error. For example, if you're using "tcsh" and try to execute a script with "#/bin/bash", it could fail for Badly placed ()'s. Doing something like "bash -n script_name" will NOT show errors because you're using bash to scan the script. And "bash -x script_name" will probably execute properly as well.
You need that "!" in the invocation line: #!/bin/bash
You need that "!" in the invocation line: #!/bin/bash

LIBBASH(7) libbash Manual LIBBASH(7) NAME
libbash -- A bash shared libraries package. DESCRIPTION
libbash is a package that enables bash dynamic-like shared libraries. Actually its a tool for managing bash scripts whose functions you may want to load and use in scripts of your own. It contains a 'dynamic loader' for the shared libraries ( ldbash(1)), a configuration tool (ldbashconfig(8)), and some libraries. Using ldbash(1) you are able to load loadable bash libraries, such as getopts(1) and hashstash(1). A bash shared library that can be loaded using ldbash(1) must answer 4 requirments: 1. It must be installed in $LIBBASH_PREFIX/lib/bash (default is /usr/lib/bash). 2. It must contain a line that begins with '#EXPORT='. That line will contain (after the '=') a list of functions that the library exports. I.e. all the function that will be usable after loading that library will be listed in that line. 3. It must contain a line that begins with '#REQUIRE='. That line will contain (after the '=') a list of bash libraries that are required for our library. I.e. every bash library that is in use in our bash library must be listed there. 4. The library must be listed (For more information, see ldbashconfig(8)). Basic guidelines for writing library of your own: 1. Be aware, that your library will be actually sourced. So, basically, it should contain (i.e define) only functions. 2. Try to declare all variables intended for internal use as local. 3. Global variables and functions that are intended for internal use (i.e are not defined in '#EXPORT=') should begin with: __<library_name>_ For example, internal function myfoosort of hashstash library should be named as __hashstash_myfoosort This helps to avoid conflicts in global name space when using libraries that come from different vendors. 4. See html manual for full version of this guide. AUTHORS
