Sending a mail from a linux shell script

Question

I want to send an email from a Linux Shell script. What is the standard command to do this and do I need to set up any special server names?

Answer 1

you can use 'email' or 'emailx' command.

(1) $ vim /etc/mail.rc # or # vim /etc/nail.rc

set from = xxx@xxx.com #
set smtp = smtp.exmail.gmail.com #gmail's smtp server 
set smtp-auth-user = xxx@xxx.com #sender's email address
set smtp-auth-password = xxxxxxx #get from gmail, not your email account passwd
set smtp-auth=login

Because if it is not sent from an authorized account, email will get to junk mail list.

(2) $ echo "Pls remember to remove unused ons topics!" | mail -s "waste topics" -a a.txt developer@xxx.com #send to group user 'developer@xxxx.com'
