          The first character after s is used as a separator. You chose /, so the correct command would be:



          s/search/replace/flags



          The problem is you have extra / in your search part:



          <check-valid-connection-sql>select 1</check-valid-connection-sql>
          ^


          So sed parses it like this:



          Search:   <check-valid-connection-sql>select 1<
          Replace: check-valid-connection-sql>
          Flags: /g


          And / is not a correct flag.



          Use a different separator to fix this:



          s#<check-valid-connection-sql>select 1</check-valid-connection-sql>##g

          • You can also escape the '/' character with a backslash like '/'.
