Futil

Futil is a handy Python based CLI tool that performs several useful functions to search/compare/decode/encodefiles. But wait, there is more! You can also extract EXIF and Metadata with F_util. This Runs on Windows, macOS, and Linux with the only requirement being python3.

Requirements:

Python3

If you do not have python3 install, follow the option below that matches your OS.

Windows:

Download the Python 3 installer from the official website (https://www.python.org/downloads/windows/) and run it.

macOS:

Install Python 3 using Homebrew

First, install Homebrew:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" 

then run

brew install python3 

Make this even easier by creating an alias:

 alias futil='python3 /Users/cmd/script_s/fileutil.py' >> ~/.zshrc

Linux:

Use the package manager of your Linux distribution to install Python 3. *you can also use homebrew to install, see macOS install above

run the command

 sudo apt-get install python3

Create alias to allow quick use by just typing "futil" from any where on your UNIX based machine, add the following line to your shell configuration file (e.g., ~/.bashrc or ~/.zshrc):

echo 'alias futil="python3 /path/to/futil.py"' >> ~/.bashrc && source ~/.bashrc

USAGE:

futil

This can be used without setting an alias:

cd futil

python3 futil.py
