Thank for you anserw but the result is bad again :)
I tryed this : sed "s/MAKE_ARGS\([^{]*\){/MAKE_ARGS\1{\n\t'mail\/nbsmtp'
=> 'WITH_IPV6=1 WITH_SSL=1',/" > /usr/local/etc/pkgtools.conf
but i have this with cat /usr/local/etc/pkgtools.conf
MAKE_ARGS = {nt'mail/nbsmtp' => 'WITH_IPV6=1 WITH_SSL=1',
}
Sed and csh is strange no ? I think \n \t not supported by csh.
