Since I had tested and updated the repository, I should also update
the README.md as well. Hence, let's do this.

This patch updates README.md to reflect the latest implementations.

This is a reference repo serving as a sharing and quality control location for
my polygot command script that can be operated in both UNIX and WINDOWS
environment. This script is generally used for multi-system distributions where
a common initializing point is a lot easier to maintain than multiple
os-oriented shell scripts.

scripts: **The same script can be operated in both UNIX and WINDOWS OSes**. This
script is generally used various multi-system distributions and fleet control

## The Product
The product is located in the root repository called `script.cmd`.
## The Products
The products are located in the root repository in various versions:

Due to Windows' complexity and heavy requirement for file extension, the file
**MUST be suffix with the batch script extension: the `.cmd`**. Such phenomenon
is unseen in UNIX environment.

It is always advisable to keep this script as simple as calling the OS-specific
initializing command rather than develop a
[fat binary](https://en.wikipedia.org/wiki/Fat_binary) like executable script.
Example:

```
echo >/dev/null # >nul & GOTO WINDOWS & rem ^


## File Extensions
While UNIX systems do not demand for file extensions, Windows do have its
complex and heavy requirement for it. As a practice, the file extension shall
always be lead by the UNIX (`.sh*`) and ends with Windows (either `*.cmd` for
Batch initialization or `*.ps1` for PowerShell initialization).

For the highest portability, I recommend keeping the initialization with Batch
mode since its execution can auto-correct to PowerShell mode when available
(Refer [posix-powershell.sh.ps1](posix-powershell.sh.ps1) for how it's done).

Hence, this is the Polygot script's file extension I would recommend:

```
filename.sh.ps1.cmd # start by Batch
filename.sh.cmd.ps1 # start by PowerShell
filename.sh.cmd
filename.sh.ps1
```

In case you don't know, coding either the SHELL script or the BATCH script can
be a cumbersome task when they became large; left alone combining them in 1
file. Use proper programming languages like Go for such task.
## Maintain Simplicity for Sanity
It is always advisable to keep this script as simple as calling the OS-specific
initializing command rather than develop a
[fat binary](https://en.wikipedia.org/wiki/Fat_binary) like executable script.

In case you don't know, coding all 3 types of scripts and compile into 1
manually can be a cumbersome task as they can easily become large. Should it be
too complex, you should use proper programming languages like Go or Rust.
