Hi amit14august...
You must be using a bash version 4.x.x as it cannot be used on anything previous.
On OSX 10.12.4, DEFAULT bash terminal below occurs...
So it is not backwards compatible.
To find your bash version:-
It is not easy to include users who do not have versions of languages that you write for and possibly unable to upgrade to. So be aware when you write your code to state which version of language you are using as that helps the user to decide whether or not to run your code.
We all learn the hard way.
Good luck and keep up with the programming learning curve.
We look forwards to seeing more from you...

Here's a regex substitution operation that has stumped me with sed:
How do you convert lines like this:
first.key ?{x.y.z}
second.key ?{xa.ys.zz.s}
third.key ?{xa.k}
to:
first.key ?{x_y_z}
second.key ?{xa_ys_zz_s}
third.key ?{xa_k}
So i'm basically converting all the... (11 Replies)

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.
