NAME

mount_ptyfs — mount the /dev/pts file system

SYNOPSIS

mount_ptyfs

[-g group|gid] [-m mode] [-o options] ptyfs mount_point

DESCRIPTION

The mount_ptyfs command attaches an instance of the pseudo-terminal device filesystem to the global filesystem namespace. The conventional mount point is /dev/pts. The directory specified by mount_point is converted to an absolute path before use. This command is normally executed by mount(8) at boot time.

The filesystem contains pseudo-terminal slave device nodes which are allocated dynamically via ptm(4), or they are already open via traditional BSD style ptys.

The options are as follows:

-g group|gid

Specify the group ownership of the slave pseudo-tty.

-m mode

Specify the default mode of the slave pseudo-tty.

-o

Options are specified with a -o flag followed by a comma separated string of options.

mount_ptyfs specific options are group which corresponds to -g, and mode which corresponds to -m. See the mount(8) man page for possible options and their meanings.

FILES

n

The nth pseudo-terminal device in use.

SEE ALSO

HISTORY

The mount_ptyfs utility first appeared in NetBSD 3.0.

BUGS

When multiple instances are mounted, they all display the union of the ptys used in each instance, not just the ones used in the particular instance.
