[No one responded to this before, so I am trying again] Has anyone written a program for doing mass changes to list headers? I'm talking about doing text substitutions in the headers of many lists at the same time. One example of the need for this is that we just left BITNET and now have over 90 lists with our old BITNET node name in Owner keywords. We would like to do a mass change to correct this. There are other cases where our default values for list header keywords have changed over time because of changes in our environment. We would like to have a simple way to make the changes to hundreds of existing lists. We are using LISTSERV on Solaris.
