I spent a couple of hours this afternoon doing an export of the latest
OSProcess/CommandShell packages to a couple of GitHub repositories for
benefit of Pharo users.
 
The updates have been available for Squeak for some time, since I do all
development in Squeak and use SqueakSource as the upstream repository.
But I'm not sure that I ever bothered mentioning it on the list here.
 
So in case it may be of interest, here is a recently added feature that
may be of some general usefulness:
 
   OSProcess outputOf: 'ls -lR | wc -l'
 
This is a convenience method that handles parsing, piping, and error handling
for a unix-style command pipeline. Both OSProcess and CommandShell must be
loaded. Any errors detected in the external commands will be displayed in a
Squeak debugger. If that happens, proceed through the debugger to obtain the
final stdout result.

OSProcess/CommandShell can be loaded with the SqueakMap package loader, or:

	Installer ss project: 'OSProcess'; install: 'OSProcess'.
	Installer ss project: 'CommandShell'; install: 'CommandShell'.
