How to send mail using linux shell script

Question

Is there any command I can use to send email using a linux shell script? Or do I have to use some special server or something?

Answer 1

If you've already configured the server, with MTA running on it you can just use the mail command.

Lets say you have a file whose content you wan to send in a mail, You can do this:

$ cat /path/to/file | mail -s "your subject" your@email.com

for more information use:

man mail
