ifplugstatus is an utility which may be used to detect the link status of a local Linux ethernet device, much in the same way mii-diag, mii-tool and ethtool work. In fact it supports all three different APIs these three tools use.

ifplugstatus may be used in shell script since it returns the
current status as return value. It is especially useful to
