   # Do something
elif [ $DUPLEX = Half ]
   # Do something else
fi

This is just the starting point I need. Thank you so much! I'll plug in the parameters I need and post the results!

Pardon my lack of knowledge here but I seem to be getting syntax errors with the "fi" at the end of the file? I tried running the dos2linux command to ensure there are no weird characters at the end of the file. Am I missing something within?

starbuck:/home/acc4000d # ./duplex72
./duplex72: line 8: syntax error near unexpected token `fi'
./duplex72: line 8: `fi'


Code:
#!/bin/sh
DUPLEX=$(ethtool eth0 | sed -n 's/Duplex:\(.*\)/\1/p')
if [ $DUPLEX = Full ]
then
   echo "All is good in the neighborhood"
elif [ $DUPLEX = Half ]
    echo "Check eth0 settings, I am at 100 half duplex. Do IT NOW!!!"
fi

if_txp

TXP(4)							   BSD Kernel Interfaces Manual 						    TXP(4)

NAME

     txp -- 3Com 3XP Typhoon/Sidewinder (3CR990) Ethernet interface

SYNOPSIS

     To compile this driver into the kernel, place the following line in your kernel configuration file:

	   device txp

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   if_txp_load="YES"

DESCRIPTION

     The txp interface provides access to the 10Mb/s and 100Mb/s Ethernet networks via the 3Com Typhoon/Sidewinder chipset.

     Basic Ethernet functions are provided as well as support for vlan(4) tag removal and insertion assistance, receive ip(4), tcp(4), and udp(4)
     checksum offloading, and transmit ip(4) checksum offloading.  There is currently no support for transmit tcp(4) or udp(4) checksum offload-
     ing, tcp(4) segmentation, nor ipsec(4) acceleration.

     When a txp interface is brought up, by default, it will attempt to auto-negotiate the link speed and duplex mode.	The speeds, in order of
     attempt, are: 100Mb/s Full Duplex, 100Mb/s Half Duplex, 10 Mb/s Full Duplex, and 10 Mb/s Half Duplex.

     The txp supports several media types, which are selected via the ifconfig(8) command.  The supported media types are:

     media autoselect
	     Attempt to autoselect the media type (default)

     media 100baseTX mediaopt full-duplex
	     Use 100baseTX, full duplex

     media 100baseTX [mediaopt half-duplex]
	     Use 100baseTX, half duplex

     media 10baseT mediaopt full-duplex
	     Use 10baseT, full duplex

     media 10baseT [mediaopt half-duplex]
	     Use 10baseT, half duplex

HARDWARE

     The txp driver supports the following cards:

	   o   3Com 3CR990-TX-95
	   o   3Com 3CR990-TX-97
	   o   3Com 3cR990B-TXM
	   o   3Com 3CR990SVR95
	   o   3Com 3CR990SVR97
	   o   3Com 3cR990B-SRV

SEE ALSO

     altq(4), arp(4), inet(4), intro(4), ip(4), miibus(4), tcp(4), udp(4), vlan(4), ifconfig(8)

HISTORY

     The txp driver first appeared in OpenBSD 2.9.
