AndyDeny

ifconfig eth0 | sed -n '/inet /p' | sed 's/inet.*r://'|sed 's/B.*$//'
ifconfig eth0 | sed -n '/inet addr/p' | awk -F'[: ]+' '{print $4}'
ifconfig | sed -n '/eth0/{N;s/.*inet addr://;s/ .*//p}'
ifconfig | awk '/eth0/{getline;gsub(/addr:/,"",$2);print $2}'
ifconfig | awk -F"[ \t:]+" -vdev=eth0 '$2=="Link"{d=$1==dev?1:0}d&&/inet addr:/{print $4}'
ifconfig eth0 | sed '/inet addr/!d; s/.*inet addr://; s/ .*//'
ifconfig eth0 | awk -F '[: ]+' '/inet addr/{print $4}'
ifconfig eth0 | awk '/inet addr/{gsub(/addr:/,"",$2);print $2}'
ifconfig eth0 | awk -vRS='inet addr:' 'NR!=1{print $1}'
ifconfig eth0 | grep -Po '(?<=inet addr:)\S+'
