So  the concept of a  wildcard  in Regular Expressions works a bit differently  In order to match  any character  you would use      The     modifier means  match any number of times

The asterisk     means  zero or more of the previous item    If you want to match any single character use  sed -i  s string-  string-0 g  file txt   If you want to match any string  i e  any single character zero or more times  use  sed -i  s string-   string-0 g  file txt
