Going out on a limb here regarding exact command line options, but you could
use the 'sed` command, the stream editor to do this at the command prompt:
$ sed s/(^[A-Z].*[A-Za-z0-9]$)/\f\1/g in.txt > out.txt
or:
$ sed s/\(^[A-Z].*[A-Za-z0-9]$\)/\f\1/g in.txt > out.txt
if `(' needs to be escaped. Not sure if '\f` would insert page breaks either
-- might have to access the direct ASCII value, but anyways.
The `s' in the sed regular expression pattern instructs sed that you want to
do a substitution.
