7zip CLI to Generate sha256 Checksum File
On Windows you have a nice option to right click on a file and have 7zip generate a sha256 file that sits next to the file. I wanted to script up a linux file server to go through and 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 say (view sourcecode)
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
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 {} +
