I tried "top -m" on ubuntu and it didn't know what that was...<br>

<br>
During normal operation you can override the secreen size detection via<br>
the environment variable $LINES, ala:<br>
<br>
LINES=10 top<br>
<br>
But that doesn't affect -b mode...<br>
<br>
> But this '-m' option is not supported yet in toybox code.<br>
<br>
My assumption was if you're using "top -bn1" you'd pipe it through "head<br>
-n ##", to trim the output, but I suppose I can see it being useful for<br>
multiple -b output iterations...<br>
<br>

<br>
I.E. this is a feature request to add -m to top? :)<br>
<br>
Hey Elliott, given this was an android addition to begin with, what do<br>
you think? (It's easy enough to add...)<br>
<br>
Rob<br>
<br>
P.S. Poking at this, top and iotop have a common option block but -H and<br>
-O weren't applied to iotop so either they should be or the options<br>
should be moved to the earlier quoted string in the NEWTOY macro to mark<br>
them as not common... And -O differs because iotop uses it to mean<br>
something else. But maybe -H can be shared...<br>
