My system runs under RedHat 5.0, having previously run under 4.1 and
4.2, and I anticipate upgrading to RedHat 5.1 when it's released...

No problem...
Actually, it CAN be done a different way, but the alternative is
considerably more complex. Using the NFS approach means that all the
complex bits are irrelevant since the NFS does them for us...
In case you want to investigate it, the basic non-NFS approach is as
follows:
1. Use ftp to download a directory listing of the relevant updates
directory from RedHat's site.
2. FETCH=''
3. Step through that listing one line at a time, applying the
following steps to each line.
A. Assign the filename in the line to the variable LATEST
B. PREFIX=`echo $LATEST | sed 's/-[0-9]\./ / | cut -d ' ' -f 1`
C. CURRENT="`rpm -q $PREFIX 2> /dev/null`"
D. if [ "$CURRENT" != '' ]; then
if [ $CURRENT != $LATEST ]; then
FETCH="$FETCH $LATEST"
fi
fi
If, after the above procedure has been executed, the environment
variable FETCH is non-blank, then there are updated RPM's available,
so start up an AnonFTP session to RedHat's site and grab the ones
listed in $FETCH into a local directory, then "rpm -Uvh" the ones
you've just downloaded...
Best wishes from Riley.
