Question

我想在下面的例子中首先删除“/”之后的数字。（即22766）

%ASA-4-106023: Deny udp src inside:10.252.0.175/22766 dst outside:192.5.5.241/53 by access-group
%ASA-4-106023: Deny udp src inside:10.252.0.175/53967 dst outside:198.41.0.4/53 by access-group

%ASA-4-106023: Deny udp src inside:10.252.0.175/13587 dst outside:192.5.5.241/53 by access-group

Answer 1

使用以下sed方法：

line="%ASA-4-106023: Deny udp src inside:10.252.0.175/22766 dst outside:192.5.5.241/53 by access-group"
$ echo "$line" | sed -E 's/\/[0-9]+/\//'

输出：

%ASA-4-106023: Deny udp src inside:10.252.0.175/ dst outside:192.5.5.241/53 by access-group

-E选项允许扩展正则表达式（同样是-r选项）

要获得更多＆＃34; solid＆＃34; （便携式）和简化解决方案，请使用以下内容：

sed  's~/[0-9]*~/~' testfile

~作为sed表达式

中的分隔符

Answer 2

@Bhavik：尝试：考虑你的Input_file应该与提供的一样。

awk -F"/" '{sub(/[0-9]+/,"",$2);print}' OFS="/"   Input_file

将字段分隔符设置为“/”。所以只有sub（替换函数内置awk）才会改变输入文件的第二个字段中的所有数字。

Answer 3

awk '{sub(/..... dst/," dst")}1' file
