This is slightly different, as it will not delete things like /^Med/ or
/^Nxx/ which the OP probably wants to delete.

True for Linux. But you won't believe it; there's still a lot
commercial Unixes out there with Kornshell as default and that
don't have bash installed and the admins even not allowed to
install that bash beast.

Probably :-)

Though the geeks of my kind are typically called Dinosaurs, so
letting the term Geeks available free for the Linux users who
continue the crusade of Unix users against the pest and some such.

Yup, that's right, this should then do, steer crazy but working ;-)
$ <file sed '/^..[^w]/d' | sed '/^.[^e]./d' | sed '/^[^N]../d'

Not yet :-)

You also have to consider lines *shorter* than three characters, which have
to be deleted as well as there's obviously no way they can match /^New/:

$ <file sed '/^..[^w]/d' | sed '/^.[^e]./d' | sed '/^[^N]../d' | \
sed '/^.\{0,2\}$/d'

Removing some redundancy and putting everything in a single program, we have

$ <file sed '/^..[^w]/d;/^.[^e]/d; /^[^N]/d; /^.\{0,2\}$/d'

Seriosuly, use /^New/! and be happy :-)

Oh well, yes, I wouldn't use the last posts I made, except " sed -n '/^New /p' "
but that was only in case the OP was really cornered to have and use ludicrous
extents ,-)
