MOUNT(1M) UNIX Programmer's Manual MOUNT(1M)


NAME

    mount, umount - mount and dismount file system

SYNOPSIS

    /etc/mount [ special name [ -r ] ]
    /etc/umount special

DESCRIPTION

    _M_o_u_n_t announces to the system that a removable file system
    is present on the device _s_p_e_c_i_a_l. The file _n_a_m_e must exist
    already; it must be a directory (unless the root of the
    mounted file system is not a directory).  It becomes the
    name of the newly mounted root.  The optional last argument
    indicates that the file system is to be mounted read-only.
    _U_m_o_u_n_t announces to the system that the removable file sys-
    tem previously mounted on device _s_p_e_c_i_a_l is to be removed.
    These commands maintain a table of mounted devices.  If
    invoked without an argument, _m_o_u_n_t prints the table.
    Physically write-protected and magnetic tape file systems
    must be mounted read-only or errors will occur when access
    times are updated, whether or not any explicit write is
    attempted.

FILES

    /etc/mtab mount table

    mount(2), mtab(5)

BUGS

    Mounting file systems full of garbage will crash the system.
    Mounting a root directory on a non-directory makes some
    apparently good pathnames invalid.
