Bash Script Editor for Linux Bash Consolidated instance

Description : This is a relatively simple bash script editor, but has been tested. The reason for writing this blog is to practice the loop control language, functions, positional parameters, local variables, and function parameter calls, as well as calls between functions, as well as parameters for obtaining user options and options.

Note: The script options and the script options parameter get method use getopt and make further judgments, consult the main () function.
