Bash script needs to e-mail output

[br0ken]

Hello everyone,
I am working on a new backup script (have most of it already actually) but I want it to email all of the output to a set address much like cron jobs do. How would I be able to do this? It's basically the last part I want to do for now because it will eventually be run by cron so this part won't be needed then. But I plan on running it a few times to make sure it is working properly and may not be around when it actually finishes which is why it would be nice if I could get the output emailed to root or whatever address(es) needed.

You could direct the output from your backup utility to a file and then mail that file. Let's assume you're using tar to back things up. The the code would look something like:

LOG_FILE="/tmp/backup.log"
tar cvf tar_file directory > $LOG_FILE 2>&1
mail -s "Backup log `date`" root < $LOG_FILE

In /etc/aliases you would have the address to mail to for root. Remember to update the sendmiail aliases database if you change this file.

sendmail -bi

Or you could mail directly to the user

mail -s "Backup log `date`" username@host.domain < $LOG_FILE

Thanks alot for the help. I ended up just running it like this:

# ./daily.dvd.backup.sh | tee output.txt | mail -s "Output from backup script" me@email.com

this way I can tail the output.txt as it's running to check it out and also have all of the output e-mailed to me at the end. Again, thanks for helping me out. Gotta love the linux community.
