          Check your working directory, you might have a file named result} created



          sed -r -e '/^[a-z]/{s/^.*$/(&)/; w result' -e '}' test


          There are different ways to work around, one of them is to use -e option to separate the commands. When w is used, all the characters after it is used for filename and hence why you got the error as { didn't have an ending pair
