## Fast hack at a sysctl filesystem. The path can be either in
## dot-style (kern.mbuf.msize) or in slash-style (kern/mbuf/msize).
## Hacked as an example by Brian Grayson (bgrayson@netbsd.org) in Sep 1999.
for path in $*; do
## First, change any slashes into dots.
path=`echo $path | tr '/' '.'`
## Now invoke sysctl, and post-process the output to make it
## friendlier. In particular:
## 1. Remove the leading prefix.
## 2. Remove a now-leading ".", if any.
## 3. If we are left with " = <val>", strip out the " = " also.
