My first advice would be to concentrate. Your sloppy typing - no matter if English is your first language or not - in the template does not persuade me (at least) that you are really interested in what you do. And one of the main rules in computing is: garbage in, garbage out.
Having said that, let me comment on your code:
You have two code snippets of which a large part is nearly identical. That's good. Make that part one - the central - block of your program, and massage the input variables, be they command line parameters to the script or interactively entered on the keyboard, so they fit the needs of your main block. Input validation would be part of that as well.
You have a "first" variable, and you have the command line parameter $1. Any idea about how to transform or combine them into one input to the main block?
And then, wouldn't it be nice to get an - optimally correct - result from your calculator? I can see that calculation only in half of your equations. Reconsider.

For your line numbers, try cat -n

CREATE TEXT SEARCH 
DICTIONARY(7) PostgreSQL 9.2.7 Documentation CREATE TEXT SEARCH DICTIONARY(7) NAME
CREATE_TEXT_SEARCH_DICTIONARY - define a new text search dictionary SYNOPSIS
CREATE TEXT SEARCH DICTIONARY name ( TEMPLATE = template [, option = value [, ... ]] ) DESCRIPTION
CREATE TEXT SEARCH DICTIONARY creates a new text search dictionary. A text search dictionary specifies a way of recognizing interesting or uninteresting words for searching. A dictionary depends on a text search template, which specifies the functions that actually perform the work. Typically the dictionary provides some options that control the detailed behavior of the template's functions. If a schema name is given then the text search dictionary is created in the specified schema. Otherwise it is created in the current schema. The user who defines a text search dictionary becomes its owner. Refer to Chapter 12, Full Text Search, in the documentation for further information. PARAMETERS
name The name of the text search dictionary to be created. The name can be schema-qualified. template The name of the text search template that will define the basic behavior of this dictionary. option The name of a template-specific option to be set for this dictionary. value The value to use for a template-specific option. If the value is not a simple identifier or number, it must be quoted (but you can always quote it, if you wish). The options can appear in any order. EXAMPLES
The following example command creates a Snowball-based dictionary with a nonstandard list of stop words. CREATE TEXT SEARCH DICTIONARY my_russian ( template = snowball, language = russian, stopwords = myrussian ); COMPATIBILITY
There is no CREATE TEXT SEARCH DICTIONARY statement in the SQL standard. SEE ALSO
ALTER TEXT SEARCH DICTIONARY (ALTER_TEXT_SEARCH_DICTIONARY(7)), DROP TEXT SEARCH DICTIONARY (DROP_TEXT_SEARCH_DICTIONARY(7)) PostgreSQL 9.2.7 2014-02-17 CREATE TEXT SEARCH DICTIONARY(7)
