How to remove part of text using regular expressions?

Question

Regular Expressions

There are lists, in one list there are more than 2000 lines. Lists are presented in the following form:

- /(///(111(222)333)\\\?) @ /(///(111(222)333)\\\?) @ /(///(111(222)333)\\\?)
 - /(///(111(22)333)\\\?) @ /(///(111(22)333)\\\?) @ /(///(111(22)333)\\\?)

Now we have to remake them in such a form, which is presented below:

- 111(222)333 @ /(///(111(222)333)\\\?) @ /(///(111(222)333)\\\?)
 - 111(22)333 @ /(///(111(22)333)\\\?) @ /(///(111(22)333)\\\?)

I would appreciate any advice and assistance in resolving this issue.

Answer 1

sed
but in general, for clarity, the files would be given, it’s hard to watch without a real example.

Answer 2

You can use sed as ShamblerR pointed out .
But you can do it right in Sublime via replace
To delete, you need to mark those honors that need to be saved using brackets r'(save) delete (save)'.
And already in the replacement field, write something like
\1 New text \2
(or $1 $2)
