Both answers that you have already are useful. I would use a combination of if [ $# -lt "1" ]; then and getopts. You should start by writing a test script that will take the parameters that you want and print out the parameter passed in, specifically the optional parameters. Once you know that the script is handling the parameters correctly, then you can write the rest of the script.

build-lives-rfx-plugin-multi(1) General Commands Manual build-lives-rfx-plugin-multi(1)
NAME
build-lives-rfx-plugin-multi - builds rendered effects for LiVES
SYNOPSIS
build-lives-rfx-plugin-multi type [scripts_dir exec_dir] [build_bindir]
DESCRIPTION
This perl script builds rendered effects (RFX) plugins for LiVES. If scripts_dir is not defined then type is used to locate the plugin
scripts directory and output directory. Type can be builtin (the default), custom,
test, or builtinx. The type builtinx forces scripts_dir and exec_dir to be read from parameters and is used during LiVES install, and is
the only type which should be used if scripts_dir is specified.
Each plugin script in input directory is scanned to find its language code. The script is then passed to the script compiler for that lan-
guage. The directory location of the script_compiler may be specified by the build_bindir parameter (as is the case during LiVES installa-
tion0; otherwise the user's $PATH will be searched.
Return values the script returns the following values
0 - success 1 - the "type" parameter was not defined, or set to an invalid value 3 - the builder for a plugin script was not found
