There are many ways of doing what you want. Here is an example of one way
Code:
#!/usr/local/bin/bash

ifconfig eth0 > ifconfig.out
hwaddr=$(grep "HWaddr" ifconfig.out | cut -d " " -f 5)

if [ $hwaddr = "00:0B:CD:85:A5:8A" ]
then
    echo "match"
fi

ifconfig

IFCONFIG(8)						      System Manager's Manual						       IFCONFIG(8)

NAME

       ifconfig - configure a TCP/IP device

SYNOPSIS

       ifconfig [-I ip-device] [-h ipaddr] [-n netmask] [-iv]

DESCRIPTION

       Ifconfig  initializes a TCP/IP device setting the IP address and/or netmask.  It will report the address and netmask set.  This command may
       be used if the system has not been configured properly yet.  It is only used at boot time to set a fixed address for  a	system	without  a
       physical ethernet.  Normally the inet task will find it out by itself from the RARP server.

OPTIONS

       -h     The decimal TCP/IP address to set.

       -n     The netmask to set.

       -i     Don't set the IP address or netmask if already set.  This way ifconfig cannot interfere if the numbers have been found out by RARP.

       -v     Report IP address and netmask.  This is the default action if there are no other options.

SEE ALSO

       hostaddr(1), rarpd(8), set_net_default(8), boot(8).
