As someone else stated, the dmidecode
command is an option.
[root@sri-0000-0003 WebGui]# dmidecode -s system-uuid
03001234-1234-1234-1234-000700012345
I edited the output to hide the UUID of the system I tested on.
There are other things that you can get from dmidecode. dmidecode -t
will tell you the categories.
[root@sri-0000-0003 WebGui]# dmidecode -t
dmidecode: option requires an argument -- 't'
Type number or keyword expected
Valid type keywords are:
bios
system
baseboard
chassis
processor
memory
cache
connect
If you're using actual hardware instead of a virtual machine then dmidecode -t processor
would be a good option.
[root@sri-0000-0003 WebGui]# dmidecode -t processor
# dmidecode 3.1
Getting SMBIOS data from sysfs.
SMBIOS 3.0.0 present.
Handle 0x0041, DMI type 4, 48 bytes
Processor Information
Socket Designation: U3E1
Type: Central Processor
Family: Core i3
Manufacturer: Intel(R) Corporation
ID: E3 00 00 00 11 22 33 44
Given that the number of processor manufactures is small, this seems like a good alternate to dmidecode -s system-uuid
. However, under virtualbox, dmidecode -t processor
won't give you anything useful. I don't know about any other virtual platforms.
I'm willing to bet that dmidecode -s system-uuid
will also work inside a docker container too but, I can't verify that.
