    Sed script help

    I need to update very old mail files to make them mbox compliant. What I need to do is find all lines beginning with ^To: and put a comma between a random number of names on this To: line. So I want to replace the 2nd and all subsequent <space> on this lines with ,<space>.

    It should be something like:

    s/^To: [ ]/&,/2g

    But that isn't correct. Any help?

    Thanks

    Solved

    Brute force - I couldn't elegantly find a single sed command so I piped the output of one sed command to another.

    Thanks
