Which is exactly my point: a few thousand commands that are not mentioned 
anywhere except by accident.  I've been a "shell" person for decades, and 
whilst GUIs are all very well I want to know what's really happening under 
the bonnet (ObUS: hood).

For example, "dscl" looks useful but this is the first time that I've come 
across it; what other gems are awaiting me, I wonder?  And it doesn't help 
that the Mac's manpages are largely incomplete; I know, getting a bit 
off-topic for this list...
