Crud, I am unable to send a message to anyone with the data I need.

I need to use a program in UNIX like sendmail or mailx to send the following information using a single command line string.
(AKA mailx -r "blah" -s "blah" blah@b.com < blah.txt):

A text file in the body of the message
A specific name in the "From: " portion of the message.
A specific subject line.

mailx is failing when I try to have a specific subject AND a specific name in the From portion.

If anyone knows how to do this in sendmail or another standard UNIX mail function using a single line command line string, any help is greatly appreciated!

hello

i have been using "mail", my single line looks like

mail -s subj to_user@domain < blah.txt

in this coomand subject will be ="subj",
message body will be filled by text from blah.txt
and from name = $user@hostname

Sendmail , as i know didn't allow subject passing through command line...
