[systemd-devel] Udev Regex

[Boyce, Kevin P [US] (AS)]

Good Morning List,

Does anyone know how complicated of a regular expression can be utilized in a udev rule?

For instance I have a system with a lot of drives (sda through z aren't enough) and I want to write a rule that will match the physical block devices for one rule and then a separate rule for partitions.

Something like this, however the rules don't seem to fire except when I remove the '+' from the rules:
ACTION=="add", SUBSYSTEM=="block", KERNEL=="sd[a-z]+", SYMLINK+="some_device_%k"
ACTION=="add", SUBSYSTEM=="block", KERNEL=="sd[a-z]+[0-9]+", SYMLINK+="some_device_%k"

I am running systemd version 219-67.

Kind Regards,
Kevin
