You d have to define alphanumerics exactly  but      w 3 5        Should match any digit character   combination of length 3-5   If you also need the dash  make sure to escape it   -  add it  like this          w -  3 5        Also  the   anchor means that the sequence has to start at the beginning of the line  character string   and the   that it ends at the end of the line  character string   So your value string mustn t contain anything else  or it won t match
