Guys, thanks for your help. I'm a complete newbie as shell-scripting. I'm using the cygwin shell to control custom c-drivers running in windows for data-acquisition modules...Anyways, so I tried the solution suggested by @elixir_sinari and it worked. I don't understand why it works, i.e. why the single quotes and why I need to use eval. More broadly, though, I'm trying to understand what @alister is suggesting. This var2 variable is actually part of a script file that I'm developing, it contains the path to my c-driver executable. I'm utilizing this path in a lot of places in my code. Since I may change this location later, I wanted to store it in a variable that can easily be modified later. What is the alternative to this?
Now, further along in my scripting, I have another issue and it is as follows:
I have 3 variable declared
if I do
I get
so far, so good.
but if I do:
then I get this:
What the dicken's is going on here? Why is my line being overwritten by config
. At first I thought there was a limit to the number of characters per line in bash, but I did google on and found getconf ARG_MAX which returns 32000, so that isn't the issue.
I've created a c program and compiled it with gcc, in unix.
The file name is abc.c and it is run by typing the command ./abc
I have another program which creates a child process, and I need this abc program to run on that child process. I've tried execvp(), but it doesn't work.

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.
