November 24, 2004 MOUNT_PTYFS 8

### 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.
