底部 2 条垃圾线必须消失。我想使用 AWk 还是 SED？

Answer 1

由 GNU sed

sed -n '/^name-/{s///;N;s/[a-z].*\s//p}' file
JOHN      NY
TOM       TX
LILLY     LA
ROSY      WA

由 GNU awk

awk -F'[ -]+' '/name/{a=$2}/state/{print a,$3}' OFS='\t' file
JOHN    NY
TOM     TX
LILLY   LA
ROSY    WA

经过 grep

grep -o '[[:upper:]]\{2,\}' file | paste - -
JOHN    NY
TOM     TX
LILLY   LA
ROSY    WA
