[英]Matching IP address in tcl without matching dotted strings
I'm trying to find all the IP addresses in a file and replace it with this pattern " * " but I end up matching dotted strings which look like IP addresses and replace/mangle them as well. 我试图在文件中查找所有IP地址,并用“ * ”模式替换它,但最终匹配了看起来像IP地址的点缀字符串,并替换/修改了它们。 Is there way out here?
这里有出口吗? Maybe use tcl built in functions in the ip package?
也许使用ip包中内置的tcl功能?
The code looks something like this: 代码看起来像这样:
proc hide_ip { in_file } \
{
set input_file [open $in_file]
set file_content [read $input_file]
set changed false
set ip_tags [list {(((25[0-5])|(2[0-4]\d)|(1\d\d)|(0?\d?\d))\.((25[0-5])|(2[0-4]\d)|(1\d\d)|(0?\d?\d))\.((25[0-5])|(2[0-4]\d)|(1\d\d)|(0?\d?\d))\.((25[0-5])|(2[0-4]\d)|(1\d\d)|(0?\d?\d))(/((3[0-2])|([1-2]?\d)))?)} \
{(((([0-9A-Fa-f]{1,4}:){7}([0-9A-Fa-f]{1,4}|:))|(([0-9A-Fa-f]{1,4}:){6}(:[0-9A-Fa-f]{1,4}|((25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3})|:))|(([0-9A-Fa-f]{1,4}:){5}(((:[0-9A-Fa-f]{1,4}){1,2})|:((25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3})|:))|(([0-9A-Fa-f]{1,4}:){4}(((:[0-9A-Fa-f]{1,4}){1,3})|((:[0-9A-Fa-f]{1,4})?:((25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3}))|:))|(([0-9A-Fa-f]{1,4}:){3}(((:[0-9A-Fa-f]{1,4}){1,4})|((:[0-9A-Fa-f]{1,4}){0,2}:((25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3}))|:))|(([0-9A-Fa-f]{1,4}:){2}(((:[0-9A-Fa-f]{1,4}){1,5})|((:[0-9A-Fa-f]{1,4}){0,3}:((25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3}))|:))|(([0-9A-Fa-f]{1,4}:){1}(((:[0-9A-Fa-f]{1,4}){1,6})|((:[0-9A-Fa-f]{1,4}){0,4}:((25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3}))|:))|(:(((:[0-9A-Fa-f]{1,4}){1,7})|((:[0-9A-Fa-f]{1,4}){0,5}:((25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3}))|:)))(%.+)?(/((12[0-8])|(1[0-1]\d)|(0?\d?\d)))?)}]
foreach item $ip_tags {
set substituted [regsub -all -line -- $item $file_content {***} file_content]
set changed [expr {$changed || $substituted}]
}
...
192.168.1.1 --> This should match 192.168.1.1->这应该匹配
12.192.168.1.1.567 --> This should NOT match 12.192.168.1.1.567->这不应该匹配
您可以使用\\b
标记正则表达式的边界,使其与12.192.168.1.1.567
的边界不匹配。
如果要匹配192.168.1.1
而不是12.192.168.1.1.567
,则可以使用负数前瞻排除第二个匹配项。
