Hi,
I use the sendmail command to send automatic e-mail in my control programs,
but I'd like to know if there's a non interactive way to send an attachment,
like a small text file through sendmail command. I didn't find a way in the man, so anyone has already done it?.. give an example for the same thing

please help on this?

Thanks

How about using mutt?

mutt -a attachment -s "this is the subject" user@emailaddress.com < fileWITHdetail
or
echo "this is the detail" | mutt -a attachment -s this is the subject" user@emailaddress.com < /dev/null

Usage:
-a <file> attach a file to the message
-b <address> specify a blind carbon-copy (BCC) address
-c <address> specify a carbon-copy (CC) address
-e <command> specify a command to be executed after initialization
-f <file> specify which mailbox to read
-F <file> specify an alternate muttrc file
-H <file> specify a draft file to read header from
-i <file> specify a file which Mutt should include in the reply
-m <type> specify a default mailbox type
-n causes Mutt not to read the system Muttrc
-p recall a postponed message
-R open mailbox in read-only mode
-s <subj> specify a subject (must be in quotes if it has spaces)
-v show version and compile-time definitions
-x simulate the mailx send mode
-y select a mailbox specified in your `mailboxes' list
-z exit immediately if there are no messages in the mailbox
-Z open the first folder with new message, exit immediately if none
-h this help message

You can use mailx (which uses the Sendmail executable) command:

mailx -s "Subject Line" user@somewhere < /name/of/text_file

In your example, I believe the contents of text_file would be in the BODY of the email...not as an attachment.
happy new year,
