current firmware and update available

[C4Wiz]

is it possible to have rpi-update tell you what the current version installed is and what you are upgrading to?

[popcornmix]

Try:
sudo JUST_CHECK=1 rpi-update

[C4Wiz]

$ sudo JUST_CHECK=1 rpi-update
*** Raspberry Pi firmware updater by Hexxeh, enhanced by AndrewS and Dom
*** Performing self-update
*** Relaunching after update
*** Raspberry Pi firmware updater by Hexxeh, enhanced by AndrewS and Dom
*** Your firmware is already up to date

[popcornmix]

Try it again now as there has been a new update.

[C4Wiz]

nope still no notification of what you have or what is being downloaded, it just self updates and starts to download new firmware

It won't download new firmware with JUST_CHECK=1.
Can you report exactly what you typed in and what the output was?

[C4Wiz]

it is posted above

[popcornmix]

But that looks like you ran:
sudo rpi-update
You are supported to run:
sudo JUST_CHECK=1 rpi-update
to see what (if anything) has changed before updating.

[C4Wiz]

using JUST_CHECK=1

sudo JUST_CHECK=1 rpi-update
*** Raspberry Pi firmware updater by Hexxeh, enhanced by AndrewS and Dom
*** Performing self-update
*** Relaunching after update
*** Raspberry Pi firmware updater by Hexxeh, enhanced by AndrewS and Dom
*** Your firmware is already up to date

still 0 info on current

[C4Wiz]

it should say by default!!

[popcornmix]

If you want to see what you get when there are changes then you can fake it:

pi@domnfs:~ $ echo 39054eaf0d3cfa351f2e23126e0ae88596a9437d | sudo tee /boot/.firmware_revision

[C4Wiz]

just want a simple, current version is 4.4.15, available version 4.4.17, would you like to update?y/n?

[popcornmix]

That doesn't make sense as most updates don't affect the kernel version.
What happens if there were just gpu changes since last update?

[C4Wiz]

then those would be displayed as above

[C4Wiz]

right now there is 0 info on what is being updated, it just updates

[popcornmix]

It is up to you. Run:
sudo JUST_CHECK=1 rpi-update
to check what has changed. If you want the changes run
sudo rpi-update

You may also check the github repo for commits (and can even follow it to get email notifications).
You could always create a trivial bash script to run the two commands with a prompt in between.
You can use read for this.
