Getting the ESXi version from the console
Posted by jpluimers on 2016/03/10
Since ESXi is based on busybox, it is using ash a variation of sh (the classic bourne shell) called Almquist shell and most nxes use some form of bash a lot of things won’t work.
For instance, doesn’t support sh –version.
Luckily there are uname -mrs and (more elaborate) vmware -vl to get the version.
Note there is support busybox aliases so alias dir=”ls -laF” works, and you can define aliases for the version information too.
