regex - What is the Regular Expression For "Not Whitespace and Not a hyphen"

Question

I tried this but it doesn't work :

[^s-]

Any Ideas?

Answer 1

[^s-]

should work and so will

[^-s]

• [] : The char class
• ^ : Inside the char class ^ is the negator when it appears in the beginning.
• s : short for a white space
• - : a literal hyphen. A hyphen is a meta char inside a char class but not when it appears in the beginning or at the end.
