IP=LANG= ifconfig eth0 | awk "{print $2}" | cut -f2
B.
IP=$(LANG= ifconfig eth0 | grep inet | cut -d: -f2)
C.
IP=’LANG= ifconfig eth0 | awk "{print $3}"’
D.
IP=’LANG= ifconfig eth0 | grep inet | cut -d: -f2 | awk {print $1}’
E.
IP=$ (LANG= ifconfig eth0 | grep inet | awk "{print $2}" | cut -d: -f2)
must be:
IP=$(LANG= ifconfig eth0 | grep inet | awk “{print \$2}” | cut -d: -f2)
