以下代码经过测试通过，系统centos 6.3
一、匹配或
sed 匹配100_1000或bigger_1000
sed -n '/100_1000\|bigger_1000/p' 20160220
sed -n '/\(100_1000\|bigger_1000\)/p' 20160220
awk匹配100_1000或bigger_1000
默认是$0匹配，所以写不写均可
awk '/100_1000/||/bigger_1000/{print $0}' 20160220 | head
awk '$0~/100_1000/||/bigger_1000/{print $0}' 20160220 | head
grep匹配100_1000或bigger_1000 -E选项表示扩展的正则表达式
grep -E '(100_1000|bigger_1000)' 20160220 | head
二、匹配与
sed匹配与
sed -n '/19000/{/100_1000/p}' 20160220 | head
awk匹配与
awk '/19000/&&/100_1000/{print $0}' 20160220 | head
awk '$0~/19000/&&/100_1000/{print $0}' 20160220 | head
grep匹配与
grep -E '(19000.*100_1000|100_1000.*19000)' 20160220 | head
