<SOLVED> -bash: sha256sum: command not found; verify ISO, Integrity check, v18.3, Mac OSX El Capitan

Postby weinbefe » Sun Dec 10, 2017 9:10 am

Hi, I am using OS X El Capitan v10.11.6 on a Macbook Pro (15'', Mid 2012), 2,3 GHz Intel Core i7

My plan is to install Linux Mint instead. When I want to verify my ISO as written here:
https://linuxmint.com/verify.php

I've created the ISO folder and copied the files into it.

For the Integrity Check I entered the commands:

cd
cd ISO
sha256sum -b *.iso

But instead of the SHA256 sum of my ISO file, I get the following message:

"-bash: sha256sum: command not found"

Here's what it looks like:

Thanks! Hope you can help..

"-bash: sha256sum: command not found"
...i think that on this OS the command should be shasum -a 256...

Thank you for your reply. Now the name of the shell or the window changed, but nothing else happened.

Hello, weinbefe.

You have to specify the name of the downloaded ISO image file as well, else shasum does not know which data to process.

Code: Select all

shasum -a 256 /path/to/linuxmint-18.3-cinnamon-64bit.iso

Note:
/path/to/linuxmint-18.3-cinnamon-64bit.iso is only a placeholder and has to be replaced by the correct pathname and filename on your system.

HTH,
Karl

Lol! :D
Co-operation & solidarity between people always yields good results - it's the money hungry powers-that-be that cause problems... :(
