RE: Stumped on editfiles problem

[Wheeler, John]

Not that it helps you, but two of the five work for me on cfengine 2.0.6
solaris 2.8


control:
        actionsequence = (
                        editfiles
                        )
        IfElapsed = ( 0 )

editfiles:
        { /etc/inetd.conf
# works         CommentLinesMatching "^\<daytime\>.*"
# works         CommentLinesMatching "^daytime\>.*"
# doesn't work  CommentLinesMatching "^daytime\W+.*"
# dosen't work  CommentLinesMatching "^daytime[:space:].*"
# dosen't work  CommentLinesMatching "^daytime\b.*"
        }
