NAME
     devattr -- tool for displaying devices and their associated properties

SYNOPSIS
     devattr [-AhM] [-p property] [-d device] [-m key:value] [-r key:value]

DESCRIPTION
     The devattr tool is for displaying a list of devices and some associated
     properties such as their name.  This tool exposes the same functionality
     provided by the devattr(3) library, namely the filtering capabilities
     offered.

     The options are as follows:

     -A      Excludes aliases from the listing.

     -h      Displays a help message.

     -M      Continue monitoring after initial scan.  Program continues
             monitoring for changes and does not exit until killed.

     -p      Only display the specified property.  This can be can be
             specified multiple times and combined with all other options.

     -d      Only display devices with name device.  When used with -p, only
             the specified properties of device are listed.  Can be specified
             multiple times.  Allows wildcards.

     -m      Only display devices whose property key matches with wildcards
             value value unless the key-value pair starts with ~, in which
             case the match is inverted.  Stacks with -p, -d, -m.  Can be
             specified multiple times.

     -r      Behaves similarly to -m, but matches with regex.

EXAMPLES
     List all devices named 'pts/0':

           devattr -d pts/0

     List all devices whose major number is 64:

           devattr -m major:64

     List all devices whose name is 'pts/0' and major number is not 64:

           devattr -d pts/0 -m ~major:64
