Morning Alan, I'll have a look at it. I can see the sense in having Java
do a load of the work. Esp when doing things like listing directories
and such.
There are times however when I will need to run specfic system commands,
for instance cvs checkout and sudo. In those cases it still looks like I
will need to start a sub process via Runtime but that will be okay
because they would occur on rarer occasions.
I was going to ask about how resource hungry but I've just seen the
figures, 600k mem and around 2.5% cpu on a 450. This was for running a
cvs checkout.

In this instance, in theory, it will. The requirement for a CVS Servlet
frontend is part of an inhouse proposal to move the companies work areas
to being stored on a Linux server and just made available as a network
drive via samba. Everyone in the company uses Windows boxes, bar us
(Linux), and the guy putting the propsal forward is a Linux bod (and a
contracter). To do part of this we need to run sudo, so that the project
gets checked out from CVS as the particular user and to his or her home
directory.

Thank you :)
