regular expression: match any word until first space

Question

I have the following line:

hshd    household   8/29/2007   LB

I want to match anything that comes before the first space (whitespace). So,

Answer 1

for the entire line

^(\w+)\s+(\w+)\s+(\d+(?:\/\d+){2})\s+(\w+)$

Answer 2

Perhaps you could try ([^ ]+) .*, which should give you everything to the first blank in your first group.

Answer 3

I think, a word was created with more than one letters. My suggestion is:

[^\s\s$]{2,}

Answer 4

([^\s]+)

works

Answer 5

^([^\s]+) use this it correctly matches only the first word you can test this using this link https://regex101.com/

Derived from the answer of @SilentGhost I would use:

^([\S]+)
