Sean,
A couple of examples that might be helpful:
(1) ping somebody and get the output:
^( PipeableOSProcess command:'ping ', host, ' -c 4' ) output.
(2) from the selector name, I'm guessing that Dave was kind enough to send me
this example in the days when I was completely (vs. now partially) clueless
about the correct use of OSProcess:
tryDave
| gp |
gp := PipeableOSProcess command:'gnuplot'.
gp setNonBlockingOutput.
gp
exec:'set output ""';
exec:'set terminal png';
exec:'plot sin(x)'.
(Delay forMilliseconds: 1000) wait. "allow gnuplot to send data"
gp upToEnd inspect. "all available stdout data"
gp errorUpToEnd inspect. "all available stderr data"
gp close.
FWIW, it appears that I use exclusively PipeableOSProcess. Note that you might
need to send #closePipes. Sadly, my comments don't say *why* I added it
(distinct from above examples), but since I'm only now finding them, the
addition must of fixed the problem I was having. Searching the archives will
likely turn up something with Dave explaining how and when to use it. Good
luck.
Bill

I didn't mean that as a dig against Squeak, just as a shorthand for "the
file system that traditionally has been included with Squeak"

Yes, I think this is the best option for now; but my inquiry was also a
nudge to add this to the FS API ;-)

I want mv because of efficiency - cp-ing & then deleting 3.5gb takes what
feels like about 30 seconds, where an mv feels instantaneous.
