mail ?

[luis <luis@aztlan.fb10.tu-berlin.de>]

hello

a very humble question

how can i send by mail a file, in only one line ?

i mean, how can send a mail with a file in its body in only one line of the 
shell, without entering <Enter> ?

when i try "mail user ." i can not send the email
also with "mail user Ctrl-D" i can not get again the shell
with which shell sequence i can convince mail or sendmail to send the
message in only one line ?

it is intended for a line in the /etc/ppp/ip-up file, so the machine
could send an email publushing its current ip

thanks a lot for this silly question
