So I can just open vi editor and list different animal names or something and those would be my line arguments?
But what your saying is the whole objective is just to display the contents ( line arguments ) of my script file with the file name? using the commands I listed

plan9-getflags
GETFLAGS(8) System Manager's Manual GETFLAGS(8)
NAME
getflags, usage - command-line parsing for shell scripts
SYNOPSIS
getflags $*
usage [ progname ]
DESCRIPTION
Getflags parses the options in its command-line arguments according to the environment variable $flagfmt. This variable should be a list
of comma-separated options. Each option can be a single letter, indicating that it does not take arguments, or a letter followed by the
space-separated names of its arguments. Getflags prints an rc(1) script on standard output which initializes the environment variable
$flagx for every option mentioned in $flagfmt. If the option is not present on the command-line, the script sets that option's flag vari-
able to an empty list. Otherwise, the script sets that option's flag variable with a list containing the option's arguments or, if the
option takes no arguments, with the string 1. The script also sets the variable $* to the list of arguments following the options. The
final line in the script sets the $status variable, to the empty string on success and to the string usage when there is an error parsing
the command line.
Usage prints a usage message to standard error. It creates the message using $flagfmt, as described above, $args, which should contain the
string to be printed explaining non-option arguments, and $0, the program name (see rc(1)). If run under sh(1), which does not set $0, the
program name must be given explicitly on the command line.
EXAMPLE
Parse the arguments for leak(1):
flagfmt='b,s,f binary,r res,x width'
args='name | pid list'
if(! ifs=() eval `{getflags $*} || ~ $#* 0){
usage
exit usage
}
