ps, test, /dev/null questions

Thu Sep 18 12:23:00 GMT 1997

Thanks for all the ideas. I tried a few:
-	ps -eAf or any other option does not work. I guess as someone 
explained, you can only see cygnus processes - not a good port IMHO. 
Also pview is a grpahical utility AND you have to have the reosurce 
kit! Anyway, if you have the resource kit, you can use the TLIST 
command.
-	Nul: works on NT, I'm not sure why, but if it is a intentional 
feature and it plans on staying, it would be a good idea to document 
it.
-	Sending anything to /dev/null does create a file that size (not 
good), however if you input from it, you don't get anything (strange 
but good)
-	test -w ./DIR/. does just the same - returns false when it 
shouldn't

use pview (NT resource kit)
pview95 (Platform SDK sample applications)
wintop (95 only? MS kerneltoys)
cygnus ps only shows procs for cygnus processes. (reasonable I think 
:).

/dev/null exists only in the mind of the cygwin.dll (and not always 
there)
try diff -ubB /dev/null file.c (use echo|diff -ubB - file.c or diff 
-urBbN ../emptydir . )
.\\NUL (./NUL) exists in every directory on FAT VFAT or NTFS
(it's a system device however it's not recognized by cygwin.dll)
(see any good dos book whoops I mean dosshell95/NT, er win32? book :)
try test -w ./DIR/. && echo itshere (the ending slash messes up stat 
I think)
