MOUNT(8)                   Linux Programmer's Manual                  MOUNT(8)



NAME
       mount - mount a filesystem

SYNOPSIS
       mount [-lhV]

       mount -a [-fFnrsvw] [-t vfstype] [-O optlist]

       mount [-fnrsvw] [-o option[,option]...]  device|dir

       mount [-fnrsvw] [-t vfstype] [-o options] device dir

DESCRIPTION
       All files accessible in a Unix system are arranged in one big tree, the
       file hierarchy, rooted at /.  These files can be spread out  over  sev‐
       eral  devices.  The mount command serves to attach the filesystem found
       on some device to the big file tree. Conversely, the umount(8)  command
       will detach it again.

       The standard form of the mount command, is

              mount -t type device dir

       This  tells  the kernel to attach the filesystem found on device (which
       is of type type) at the directory dir.  The previous contents (if  any)
       and  owner  and  mode  of  dir  become  invisible,  and as long as this
       filesystem remains mounted, the pathname dir refers to the root of  the
       filesystem on device.

       The listing and help.
              Three forms of invocation do not actually mount anything:

              mount -h
                     prints a help message

              mount -V
                     prints a version string

              mount [-l] [-t type]
                     lists all mounted filesystems (of type type).  The option
                     -l adds the labels in this listing.  See below.

       The device indication.
              Most devices are indicated by a file name (of  a  block  special
              device),  like /dev/sda1, but there are other possibilities. For
              example, in the case of an  NFS  mount,  device  may  look  like
              knuth.cwi.nl:/dir.   It  is possible to indicate a block special
              device using its volume LABEL or UUID (see the -L and -U options
              below).

              The  recommended  setup  is  to use LABEL=
