It could be very valuable to check the authenticity of old e-mails.
It's just a matter of experience with the toolchain.
You only have to be cautious when your input is mangled in some way (with escape characters etc) and your toolchain cannot cope with such things.
There are many different versions of cut, awk, sed and even jq. I don't consider this very portable.

The current version is Amazon Linux 2 and in some places this is called (release candidate)3.3.
Though I hope it will be released soon and I wonder if they will call it "Amazon Linux 3" or "Amazon Linux 2023".
But mind you; I'm quite sure it still uses overlayfs or device mapper snapshots for the root filesystem.
