inquiry to 'nvram' binary (missing some capabilities)

[Fermulator]

Hi there,

In attempting to write some automation for nvram backup/restore, I noticed a lot of users expect the nvram command to have options like import and export. However mine does not.

i.e. https://github.com/wbtf/nvram-backup/blob/master/nvram-backup.sh

# nvram export --tab output
usage: nvram [get name] [set name=value] [unset name] [show] [commit] [save] [restore] [erase] ...

I presume the version of the nvram binary is built and supplied via this firmware? (but please correct me if I'm mis-understanding)

(running latest Q4 2018 firmware)

To export nvram configuration use

nvram save > /tmp/nvram_content

To import, use nvram restore. I'm not sure if this is what you expect? :) Those both commands are used to import/export via WWW.

Thanks!

Actually, no, save nor restore are available options?

/tmp/home/root# nvram save
usage: nvram [get name] [set name=value] [unset name] [show] [commit] [save] [restore] [erase] ...
/tmp/home/root# nvram restore
usage: nvram [get name] [set name=value] [unset name] [show] [commit] [save] [restore] [erase] ...

Shouldn't these NOT prompt into usage? (I expect save for example, to either dump to stdout, or save to file)

[Michał Obrembski]

sorry, i’ve done a mistake.

It should be

‌

nvram save nameoffile.cfg

and

‌

nvram restore nameoffile.cfg

But i think that we should change the nvram prompt to be more meaningful

[Fermulator]

Confirmed, specifying the filename works .

‌

Indeed, this ticket thus can serve to improve the usage prompt.

Darn, i made the change and tried to push up but

git push origin enhancement/#15_improve_nvram_usage
