sed bug/discrepancy

[Edward Reingold]

The following sed command works perfectly in Solaris, but causes duplicated
lines when using the GNU version:

sed -n -e 's/^\\inputfun[{]\([?a-zA-Z0-9-]*\)[}].*$/\1/p' book.tex >! c

(it produces a list of all function input lines in a LaTeX file).

Never mind... the problem is my input differs in the two systems. Sorry.
