7zip CLI to Generate sha256 Checksum File

On Windows, you have a nice right click menu option to have 7zip generate a sha256 file that sits next to the original. I wanted to script up a linux system to find all iso files and place the sha256 hash next to it. As you can see from the menu, its not the easiest thing to get to.

But with this script you can just type

7zsha256 *.iso

And it will run through all the iso files in the folder and place the sha256 file next to it. If a sha256 file already exists, it will just skip that file and keep going since they take a while to generate.

To Install

curl -o 7zsha256 https://raw.githubusercontent.com/szazeski/helpers/main/7zsha256 && chmod +x 7zsha256

Or git clone the whole repo for more helpers and place it in your PATH

git clone https://github.com/szazeski/helpers.git

List All sha256

Now after you have generate sha256 files, this can list out all of the sha256 in one view.

find . -name "*.sha256" -exec cat {} +
