If you mean "What's the reqular expression to check there is no white space in a string", the following pattern will work:

^[\S]*$

This will find any string that only contains non-white space (spaces, new lines, tabs, etc).

I don't know if it is the regular expression you are looking for but, [:space:] will match any whitespace character, while [:blank:] will match space and tab characters only.

Both are used inside square brackets, e.g. [[:space:]]
