brew install cmake ninja dfu-util
On big sur you must have python3. But first type this on terminal:
brew install python38
sudo easy_install pip

I have done these steps already. You must type them on terminal or iTerm2.
These procedures must be done before flashing or coding any kind of source code.
Hello readers,
Today, we are going to learn how to install esp-idf on macOS.
But first to compile the toolchain before that, we must install by brewing the following items on terminal or iTerm2

Hello readers,
Today, we will learn how to unzip files on terminal or iTerm2.
On this example, I got a few zip files from the internet, we will show how to unzip a library zip file.
I used a folder called example for the instance workaround.
How I done this workaround. I made these few steps on my iTerm2 second tab session.
cd Downloads
mkdir example
pwd
mv example1.zip example
mv example2.zip example
mv example3.zip example
cd example
unzip \*.zip
ls
rm -rf *.zip
ls
You need always to move the zip files into a directory to get this work.
I chose Downloads folder to be easier to manage the example.
I gave you the code inline to manage and the screenshots to become easier.
Now, as you see we can always do those commands on the terminal or iTerm2 to unzip files.
