I wanna write the output of various commands as an email. I tried this:
#!/bin/bash
(echo $(date); echo $(top);sudo apt-get update && sudo apt-get upgrade -y) | mail -s "Updated!" [email protected] -a "From: UpdateNotify<[email protected]>";
The script is infinite. :/
How can I do that? I need the date,top output and the update logs in one email.
That's the right way to do it, the issue is with echo $(top). top is an interactive application so never returns.
You should look to use ps instead to list the current processes running.
( and newline before the closing ) and indentation in between. Then every command can be on its own line.jas_raj answer is correct, however if you like top's output you can run in batch mode: top -bn 1 this will make top exit right after it runs once.
have a look at cron-apt and nullmailer to send mails after system update.
