Regex for strings not starting with "/*"

What regex matches all strings except ones starting with a literal /*, meaning a slash (U+002F) followed by a star (U+002A)?

I’ve tried ^.*[^/\*] but it doesn’t seem to work for me.

EDIT: This is for matching strings that starts with a character other than / and * - stemmed from misreading the question. Ignore this.

^[^/*].*

^ Beginning of string
[^/*] Any character other than / and *
.* more characters (

^[^/*] should be all you need:

$ echo -e "*red\n/green\nblue"
*red
/green
blue
$ echo -e "*red\n/green\nblue" | egrep "^[^/*]"
blue

If you definitely need to match lines with at lease two characters you can use ^[^/*].+

that .* in the beginning is matching anything and everything. You just need to move your not block to the beginning:

^[^/*].*

You can use a negative lookahead:

^(?!/\*).*

This will match everything except if it starts with /*.

Or if you mean anything except / or *:

^[^/*].*
