Dear All,

I wonder if I might make a request for a new feature for powertop.

When I run it, I can toggle various tunable options from within the 
Powertop interface. As I understand it, the effect of these to invoke an 
underlying system command such as:
   echo value > /sys/device/power/something

But powertop never actually tells me what these commands are. This means 
I can't easily append them to my own startup scripts, or make them 
persistent across reboots.

So my wish is as follows:

When powertop actually modifies the system, it should print the 
commands, to stderr, when it exits.

Thanks very much,

Richard



P.S. Powertop 2.0 also has no manpage. May I recommend help2man.

Hello,

not all toggle actions are just one liners.

Dear Arjan,

Thanks for your reply - that is indeed helpful.

I see what you mean that there is less space on the ncurses gui. But 
using the html report is rather "non-discoverable".

For maximum friendliness, might I suggest:

1. When the user exits the ncurses gui, a log of the commands that were 
actually invoked should be printed to stderr.

2. The command that was just run could perhaps be put into the status 
bar at the bottom of the ncurses gui?

Thanks

Richard

Hi,

on the normal screen, there is not really enough real estate to put the
full command there.
however, if you run the --html report, it will give you these commands!

(the html page has a lot more space to put stuff)
