NAME

       vol_id - probe filesystem type and read label and uuid

SYNOPSIS

       vol_id [--export|-t|-l|-u] blockdevice

DESCRIPTION

       vol_id  is  normally  called from a udev rule, to provide udev with the
       label and uuid of a filesystem. vol_id supports all  common  filesystem
       formats  and  detects various raid setups to prevent the recognition of
       raid members as a filesystem.

USAGE

       vol_id opens the device node specified at the commandline.

OPTIONS

       The following commandline switches are supported to specify what vol_id
       should print:

       --export
              print  all  values  in  key/value format to import them into the
              environment.

       -l     print the label of the partition

       -t     print the type of the partition

       -u     print the uuid of the partition

EXIT STATUS

       vol_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.
