我想在此方面寻求您的帮助:
我有成千上万行的文件,我需要找到文件的一部分并删除一些行:
这是此部分,我要删除的行已标记:
interface Vlan824

此sed会删除提及的行(第三行除外),但我只需要在该部分中进行。
sed -i '/224.1/d; /224.2/d; /224.3/d; /:224::/d; /:824::/d' FILE.txt
感谢您的帮助。

假设您要编辑的部分是Vlan824(以!字符结尾),匹配删除行的模式为224.1和FE80
sed -n '/Vlan824/,//p;/^\!/q' your-file | grep -v '224.1\|FE80'

将您的命令合并为一个组,然后使用您要影响的范围来寻址该组。
sed -i '/interface Vlan824/,/!/{/224.1/d;/224.2/d;/224.3/d;/:224::/d;/:824::/d;}' foo.txt
