rootsh is deprecated?!?!?
Probably the one of the most critical things for our devices ..for lack of a better word "pooched"?
And without alarums (olde-fash-ioned term) being raised ?
I do really seriously doubt that.
I'm not sure exactly what make or model of device you are using ..
...nor the kind of commands you are trying to elicit from rootsh...
but ...
Just to test your statement ...
I just now... uninstalled and reinstalled rootsh ..
on one of my n800's ...one of my n810's...and one of my n900's...
and it still works fine to me...
sudo gainroot...bam.
soooo...unless you are using a 770...or n9.. or Jolla...
or something else I haven't tested yet...
then...it ain't rootsh .
It's all you man...

and uh-oh...
you made peter all unsmiley-facey ...
oooh and it's red too.

More deets from you would help with your problem and peter's unsmiley-smile...
