Detect if we are running on a VMware virtual machine

dmidecode | awk '/VMware Virtual Platform/ {print $3,$4,$5}'
If you run this command on a VMWare Virtual Machine, it will return the string "VMware Virtual Platform". If you run it on a physical machine, it will return nothing. Useful for having a script determine if it's running on a VM or not. Of course, you must have dmidecode installed for this to work. Try it this way in a script: ISVM=$(dmidecode | awk '/VMware Virtual Platform/ {print $3,$4,$5}') Then test if $ISVM has text in it, or is blank.

I can't think of an instance where this would actually be necessary. Nifty, yes, but useful?

I work in an environment which is a mixture of physical *nix hosts and virtual *nix hosts. We have scripts that detect if they are running on a physical box or virtual box, 32bit or 64 bit, solaris or rhel or suse, and act slightly differently based on the information detected.

Ah, okay. In that environment, I can see the use. Nice. +1

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
