I have a very stupid/simple problem, but for some reason I cannot figure out...and I need your help!
I am writting a bash scrip that should be executed using "my_script X Y Z T" where X Y Z and T can be any string, but there can be any number of arguments.
I want my script to do a list from these inputs:
Using the above script, I got:
./myfile.1 ./myfile.2 ./myfile.3 ./myfile.4
instead of:
./myfile.X ./myfile.Y ./myfile.Z ./myfile.T

I have no idea what the following means. The teacher is too advanced for me to understand fully. We literally went from running a few commands over the last few months to starting shell scripting.

The following bash script does not work because the java/groovy code always thinks there are four arguments even if there are only 1 or 2. As you can see from my hideous backslashes, I am using cygwin bash on windows.

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.
