Post what you tried because what you say you did `substituted "Ellwood1.ged" for "!~"` sounds like you replaced the regexp inequality operator with the name of a file which doesn't make sense. if you wanted to run Janis's script on a file named Ellwood1.ged you'd do: awk '$2 !~ /@.*@/ { sub(/Service/, "S.") } { print $0 }' Ellwood1.ged if you're on UNIX. If you're on Windows, it's different so tell us which OS you're on. Ed. > > I'll play with it some more. > >
