How to stop regex at the end of line

trying to figure out next case:
I have txt file with parameters



environment=trank
Browser=iexplore
id=1988
Url=www.google.com
maautomate=no

When I parse this txt file with regex pattern like

/environment=([^\s]+)/

I got "trankBrow" as result, or


/Url=([^\s]+)/

I got

[To see links please register here]

=no


So why second parameters appended? And how to get "trank" only?

environment=([^\\s]+)

You need to use this. `\s` in your case is escaping `s` and so the output is `trankBrow` because after that `s` is there.
