And when they want to use another value? (null-device) returns
"/dev/null" for local default-directory's if you're not on MS
Windows. On MS Windows, it returns "NUL".
With a remote default-directory, the value is configurable (as
connection-local variable). Per default it is also "/dev/null", but it
could be changed.
Do you want to suppress this mechanism in Eshell? Why? I guess it is
more appropriate to install a handler for the actual value of
(null-device), instead just a handler for "/dev/null" only. And if you
want to make "/dev/null" a system-independant default, add the same
handler for this in parallel. Then both would be equivalent on MS Windows:
--8<---------------cut here---------------start------------->8---
cmd ... > /dev/null
cmd ... > NUL
--8<---------------cut here---------------end--------------->8---
Best regards, Michael.
