Now I need to find udevadm I guess. It must have been introduced since the udev version that comes with RHEL/CentOS 5, which is udev-095-14.21.el5_5.1. rpmfind.net suggests it's only been in since version 118 or so. Never mind :-)
Heh. Anyone know the equivalent command in earlier versions of udev?
I think it's `udevinfo` instead of `udevadm info` - the comment in the ChangeLog for udev-117 is "udevadm: merge all udev tools into a single binary". But it doesn't work terribly well:
[root@beast describe_scsi]# udevinfo -q all -p /devices/pci0000\:00/0000\:00\:1f.2/
no record for '/devices/pci0000:00/0000:00:1f.2/' in database
That's unfortunate. But it does know about that device if asked differently:
[root@beast describe_scsi]# udevinfo -a -p /devices/pci0000\:00/0000\:00\:1f.2/
Hmmm. Can you try both of the above without the trailing slash?
Just the same output, however I ask the question:
[root@beast ~]# udevinfo -q all -p /devices/pci0000\:00/0000\:00\:1f.2
no record for '/devices/pci0000:00/0000:00:1f.2' in database
[root@beast ~]# udevinfo -q all -p /devices/pci0000:00/0000:00:1f.2
no record for '/devices/pci0000:00/0000:00:1f.2' in database
[root@beast ~]# udevinfo -q all -p /sys/devices/pci0000:00/0000:00:1f.2
no record for '/devices/pci0000:00/0000:00:1f.2' in database
[root@beast ~]#
And all with "-a" instead of "-q all" produce the output I posted before.
The modern udevadm gives me that with --attribute-walk. It's purpose is to report
the conditions one might want to use in an udev rule. It doesn't provide the human
descriptions I'm looking for.
Please don't feel you have to turn this into a project, though.
Too late. Here's a version that doesn't use udevadm at all...
