Based on [WayBack ] windows – How to run batch file command with elevated permissions? – Super User :
powershell -command "Start-Process cmd.exe -Verb runas"
This works better than "runas /user:administrator cmd.exe"
as that forces to use the specific Administrator
account, whereas the PowerShell way allows you to specify the actual account during elevation.
You can extend this to run a command with one or more parameters based on [WayBack ] Launch Elevated CMD.exe from Powershell – Stack Overflow (thanks [WayBack ] mklement0 ):
powershell -command "Start-Process cmd.exe -Verb runas -Args /k, call, goto-bin"
This will actually pass “call goto-bin
” to cmd.exe
which tries to execute the “goto-bin
” command (which I have around on the PATH
as goto-bin.bat
).
You can either use comma-separated parameters or a quoted string. In this expansion, comma-separated is easier in this PowerShell construct.

Reminder to self when checking “new” disks to see what partitions they contain before formatting them as VMFS.
There is a truckload information at [WayBack ] Using the partedUtil command line utility on ESXi and ESX (1036609) | VMware KB .
A few tips; example output is further below:
Disks are listed under /vmfs/devices/disks/
where there are two entries per device: a path leading to the device, and a link to that path which starts with vml.
which I filter out with grep.
If a disk under under /vmfs/devices/disks/
ends with :#
where #
is a number, then it is a partition
Just skip partedUtil get
as partedUtil getptbl
will give you exactly the same information,
plus an extra initial line indicating what kind of partition table it is. KB 1036609 has a longer list, but these are the ones you usually see:
unknown
: the disk has no partition table yet (usually), or the type of partition table cannot be determined (hardly)
gpt
: there is a GUID Partition Table
msdos
: there is a Master Boot Record partition table
on ESXi 6.x two extra columns listing the partition GUID and partition type description
The output of partedUtil
is unformatted, which means it is easy to parse, but hard to read for humans. You can pipe through sed 's/ /\t/g'
(as there is no tr
on the ESXi busybox)
Some more background reading
On scripting:
The shell is sh
(always been there)
There is Python
(ESXi 5.1 has Python 2.7.8
; ESXi 6.5 has Python 3.5.3
; it has likely been available in earlier versions too).
On device names:
On errors:

I know of three VMFS types:
VMFS-3: Supported in ESXi 3.X, 4.X, 5.x & 6.x; deprecated as of 6.0 (cannot be created as of 6.0), has quite some limitations.
VMFS-4: got never released.
VMFS-5: Can be converted from VMFS-3
VMFS-6: Cannot be converted from other VMFS types
Some interesting links about the various VMFS types:
Busybox has been updated over time:
Examples and output
Example outputs on one of my systems, of which I stripped most of the disks as they’re not really relevant here.

Interesting read and watch:
At the recent Embedded Linux Conference and OpenIoT Summit, Mozilla Technical Evangelist Dietrich Ayala proposed a simple and affordable solution to home automation: A discarded smartphone can handle some of the most useful home automation tasks without requiring expensive hubs and sensors — or risking data security in the cloud.
