notepad++ regular regex

Question

I have the following text:

3/1 

I want to amend it to be:

3/1 port id

Thanks

Answer 1

Can't you just do a search and replace for 3/1 replacing it with 3/1 port id?

Answer 2

Find this: (\d+\/\d+)

This means "the group of: 1 or more digits followed by a forward slash followed by 1 or more digits"

Then replace with this: \1 port id

Which means "the first group found followed by the literal text: ' port id'"
