Mutt - is a terminal-based e-mail client for unix kind of Operating systems- and has capability to send email attachements as well. However lets remember its a pure MUA and needs a working Mail Transfer Agent (MTA) such as sendmail / postfix etc.
Today I was observing an incident where user was copying a file to /tmp on the file server and from his windows desktop cmd prompt transferred to his desktop and then finally sent it to another user through his outlook..
Hope you are getting what I am trying to point out here ..
Rather a smart way could have been -
[root@DebaTestBox scripts]# mutt -s "latest User.properties" -a User.properties User@domain.com < bodymessageIfAny.txt
