Created attachment 222 [details]
Redirect failed output from which.

For example ifconfig is  being searched for with which:

IFCONFIG=`which ifconfig`
if [ -z "$IFCONFIG" ]; then
        # Is it ever anywhere else?
        IFCONFIG=/sbin/ifconfig
fi

so the output

which: no ifconfig in ${PATH}

is very confusing as it is found correctly by the next lines.

The attached patch adds a 2>/dev/null to the which invocations. It does not however do any error checking, which probably should be done.
