About The Project

This project copies the fundamental framework of the cat command-line tool from Linux and translates its features to an OS Independent program using Python.
Over time the project evolved in subject areas of other tools like 'echo', 'grep', 'ls', 'base64'.

Additionally it includes the feature to strip and reverse the content of any given file, make use of the standard-input, which enables cat piping into each other, generating the checksum of any file, converting decimal, hexadecimal and binary numbers within any text, and much more ...

Contrary to the name of the project it is of course possible to use cat_win on Linux or MacOS!

Getting Started

Prerequisites

• Using cat_win as a Python-Package demands a Python-Interpreter (>= 3.7).
• Using cat_win as an Executable (Windows only!) demands no prerequisites, hereby the stand-alone executable catw.exe is sufficient.

Installation

Simply install the python package (via PyPI-cat_win):

python -m pip install --upgrade cat_win[clip]

cat_win uses the pyperclip module by default. Should any problems occur, you can also use the pyperclip3 or pyclip module. In this case simply run:

python -m pip install --upgrade cat_win

and manually install the desired module yourself.

OR alternatively you can use the compiled version (Windows only):

1. Simply download the catw.exe file.
2. Add the file path to your system-environment PATH-variables.

⚠️ You should never trust any executable file! Feel free to compile the package yourself (e.g. using PyInstaller).

You can verify the creation of catw.exe yourself by reading the source code, checking the origin of the file and validating the corresponding workflow used.

Usage

catw [FILE]... [OPTION]...
catw --help

⚠️ from v1.0.33 to v1.1.0 the entrypoint changes from cat to catw. If you wish to keep the old command, you will have to define an alias yourself.
