It is the best way i found to send a mail from the console in my centos server.
Usage: mailme message
This is a useful function if you want to get notified about process completion or failure. e.g.
mailme "process X completed"
sudo /sbin/ifconfig | gotxt2imgmail firstname.lastname@example.org
This is a quick and easy way of encrypting files in a datastream, without ever really creating an output file from gpg. Useful with cron also, when file(s) have to be sent based on a set schedule.
This will email email@example.com a message with the body: "rsync done" when there are no processes of rsync running. This can be changed for other uses by changing $(pgrep rsync) to something else, and echo "rsync done" | mailx firstname.lastname@example.org to another command.
If you're users have ever asked your script to email their reports in separate attachments instead of tar'ring them into one file, then you can use this. You'll need the mailx package of course. In Unix you'd want to add an additional parameter "-m"
(uuencode foo.txt foo.txt; uuencode /etc/passwd passwd.txt)|mailx -m -s "Hooosa!" email@example.com
Note, this works because smtp is running
