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 '/1001000∥bigger10001001000‖bigger1000/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
