comment How to know if a machine is an EC2 instance
I like that this doesn't use the network. Would be nice to get clarification of that file path exists on all distros. I tested on Ubuntu 14 and Ubuntu 12 LTRs and the files exists on both versions.

comment Running shell script with no environmental variables
This is useful if you have a cron task which is failing because the environment is not properly configured and you need to test it; also a good way to test if your scripts make assumptions about environment settings. Thanks!

comment Setup ubuntu server to send mail()
Note on my host, the mail command-line utility is not installed on a clean Ubuntu install, and installing PostFix does not install it. Try sudo apt-get install mailutils to get the mail command, or use alternatives such as Mutt, or ssmtp

comment Is there any reason to upgrade from FreeBSD 6.x?
Yes: SCHED_ULE is much higher performance. All of my systems are 7.2 now, and the benchmarked performance with SCHED_ULE is better, by far.
