sed命令删除其中包含特殊字符的起始模式匹配

Question

I have sed command that delete line when string match with starting pattern

sed -i "/^Data\\=C\\b/Id" tally.ini

This work correctly for patch Data=C

But I want to match path Data=C:\\ and that I want to delete this line.

How can this possible?

Answer 1

sed -i  '/^Data\=C:\\/Id' tally.ini

Put the command in a single quoted string instead of double. Escape the backslash.
