mount_ptyfsmount the /dev/pts file system


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


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).

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.
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.
