NAME
       devlinktab - device link table for chk.devlink

SYNOPSIS
       /etc/devlinktab

DESCRIPTION
       /etc/devlinktab is an administrative file that contains information
       used by chk.devlink(1M) to create additional symbolic links to the
       standard device nodes created by the device drivers.

       Each line in the file is either a comment line or a device link
       entry.  Comment lines begin with the # character, and are ignored.
       Device link entries have three components, which are separated by
       white space.  The first component is the pathname of the directory in
       which the link is to be created.  The second component is the
       filename of the link to be created within that directory.  The third
       component is the target of the link to be created, expressed as a
       relative pathname from the containing directory.

       When chk.devlink(1M) processes the contents of the device link table,
       it creates links for all suffixed variants described by each entry.
       See the tape drive example below for illustration of this feature.

EXAMPLES
       The following devlinktab entry will cause /dev/tty35 to be created as
       a link to /dev/async/line/syac(vme(0),1,1E):

               /dev    tty35    async/line/syac(vme(0),1,1E)


       The following devlinktab entry will cause /dev/rmt0 to be created as
       a link to /dev/rmt/st(insc(0),4,0), and /dev/rmt0n to be created as a
       link to /dev/rmt/st(insc(0),4,0)n,:

               /dev/rmt    0    st(insc(0),4,0)
