[regex] regular expression: match any word until first space

I have the following line:

hshd    household   8/29/2007   LB

I want to match anything that comes before the first space (whitespace). So, in this case, I want to get back

hshd

This should do it:

^\S*

I think, that will be good solution: /\S\w*/

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

for the entire line

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

^([^\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]+)

Check out this interactive regexr.com page to see the result and explanation for the suggested solution.

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

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