Hi,
I'm writing a ruby script that does a batch search-and-replace command.
In each line of the file that is opened, I would like to delete part
of the entire part matched by a regrex. For example,
line.gsub(/(Tennis\/Soccer\/.+?).+?){
puts $& # entire match
puts $1 # the first match
}
I can successfuly identify the parts I need in the regres, now I want
to only keep the first match. Something like "$&" - "$1".
I tried different methods such as String#delete, but they didn't work for me.

That's not a valid regular expression as far as I can see. So the whole piece of code is not valid Ruby code.
puts $& # entire match
puts $1 # the first match
puts is not going to work for replacements.
}

Err, what? Can you please be a bit more specific? What is it that you want to match and what is your expected output?
Did you maybe mean
line.gsub! %r{Tennis/Soccer/(.+?)}, '\\1'
Note though that .+? will match a single character most of the time if you do not place another expression with a more specific pattern afterwards.

String#gsub and #gsub! are fine. You just need to use them properly.
Kind regards
