udev_volume_id - partition, filesystem, disklabel reader This program is normally called from a udev rule, to provide udev with the name, uuid or the filesystem type of a partition to name a device node. udev_volume_id opens the blockdevice node specified at the commandline. The following commandline switches are supported to specify what udev_volume_id should print to stdout: no option prints all values -h prints help text -l prints the label of the partition -u prints the uuid of the partition udev_volume_id will only return successful if the string asked for, is not empty. All trailing whitespace will be removed, spaces replaced by underscore and slashes ignored. The following rule will create a symlink named with the label string: KERNEL="[hs]d*", PROGRAM="/sbin/udev_volume_id -l %N", SYMLINK="%c" If no label is found udev_volume_id exits with nonzero and the rule will be ignored. To give it a try, you may call it on the commandline: [root@pim udev.kay]# extras/volume_id/udev_volume_id /dev/hda3 T:ext3 L:Music Store N:Music_Store U:d2da42b5-bbd9-44eb-a72c-cc4542fcb71e [root@pim udev.kay]# extras/volume_id/udev_volume_id -l /dev/hda3 Music_Store [root@pim udev.kay]# extras/volume_id/udev_volume_id -t /dev/hda3 swap Please send any comment/questions/concerns to me or: linux-hotplug-devel@lists.sourceforge.net Kay Sievers <kay.sievers@vrfy.org>
