Here we go again analysing FASTA-files. I wonder if we are going to be mentioned in the dozens of biological research papers we have helped to create over time.

Create a single bash script that does the following:
Sorry, but this is not the way that works.
First: you come across like a teacher posing the homework for us. Actually we are all professionals here and have done our homework meticulously which is why we don't have to do more homework any more. In case it was homework given to
you by
your teacher: there is a special forum for this with special rules in place. Please re-create the thread there and provide the necessary information.
Second, in case this is not homework but actually your work: we do not insist on a lot of social conventions here (after all, we are sysadmins - being somewhat autistic is part of the requirement for this job), but still a well-placed "please" here and there, along with some of the common niceties called "good manners" oils the social machinery. If you ever wonder who writes the answers to your questions: it is not some clever machine and a fat server - it is actually living, breathing persons.
Third and foremost: we are here to help you help yourself. If you want a shell-script - WRITE IT! Attempts, however failing, will count. If you tried and it didn't work, post what you did and the error you got trying to run it. We will, regardless of how long it will take, explain to you what was wrong and how to do it better (actually quite like the way i explain to you right now why you need to change your problem statement) until you understand. We will also point out ways to better solve the problem, different tools, suggest sources to find valuable information and so on and so on. But we will NOT write your code for you. We are a help forum, not your unpaid programming staff.
I hope this helps.

libbash
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.
