sed的问题

caiwolf

sed "/While/,/from/p" sedtest.txt -n
-----包含While和from的行也会被输出。假如我想包含While和from的行不输出，应该怎么修改？

bjgirl

sed -n '/while/,/from/!p' file

caiwolf

这样子不行啊。这样子包含While和from的行以及它们之间的行都被删掉了。

1. awk '/while/,/from/' file|grep -E -v 'while|from'

awk的可以，谢了。sed能实现这样的功能么？

unvalid

sed -e '1,/while/d' -e '/from/,//d'

好像笨了一点的

bjgirl

1. 
   
2. cat file|sed -n '/while/,/from/p'|sed '/while\|from/d'
