mount
Name
mount -- mount a file system
Synopsis
mount [-hV]
mount [-a] [-fFnrsvw] [-t vfstype]
mount [-fnrsvw] [-o options [,...]] [device | dir]
mount [-fnrsvw] [-t vfstype] [-o options] device dir Description
As described in POSIX 1003.1-2008 (ISO/IEC 9945-2009), all files in the system
are organized in a directed graph, known as the file hierarchy,
rooted at /.
These files can be spread out over
several underlying devices.
The mount command shall attach the file system
found on some underlying device to the file hierarchy.
Options
-v | | invoke verbose mode. The mount command shall provide diagnostic
messages on stdout . |
-a | | mount all file systems (of the given types) mentioned in /etc/fstab. |
-F | | If the -a option is also present,
fork a new incarnation of mount
for each device to be mounted. This will do the mounts on different devices or
different NFS servers in parallel. |
-f | | cause everything to be done except for the actual system call; if
it's not obvious, this `fakes' mounting the file system. |
-n | | mount without writing in /etc/mtab. This is necessary for example
when /etc is on a read-only file system. |
-s | | ignore mount options not supported by a
file system type. Not all file systems support this option. |
-r | | mount the file system read-only. A synonym is -o ro. |
-w | | mount the file system read/write. (default) A synonym is
-o rw. |
-L label | | If the file /proc/partitions is supported,
mount the partition that has the specified label. |
-U uuid | | If the file /proc/partitions is supported,
mount the partition that has the specified uuid. |
-t vfstype | | indicate a file system type of vfstype. More than one type may be specified in a comma separated list. The
list of file system types can be prefixed with no to specify the file
system types on which no action should be taken. |
-o | | options are specified with a -o flag followed by a comma-separated
string of options. Some of these options are only useful when they
appear in the /etc/fstab file. The following options apply to any
file system that is being mounted: async | | perform all I/O to the file system asynchronously. | atime | | update inode access time for each access. (default) | auto | | in /etc/fstab,
indicate the device is mountable with -a. | defaults | | use default options:
rw, suid, dev, exec, auto, nouser, async. | dev | | interpret character or block special devices on the file system. | exec | | permit execution of binaries. | noatime | | do not update file access times on this file system. | noauto | | in /etc/fstab,
indicates the device is only explicitly mountable. | nodev | | do not interpret character or block special devices on the file
system. | noexec | | do not allow execution of any binaries on the mounted file system. | nosuid | | do not allow set-user-identifier or set-group-identifier bits to take
effect. | nouser | | forbid an unprivileged user to mount the file system.
(default) | remount | | remount an already-mounted file system. This is commonly
used to change the mount options for a file system, especially to make a
read-only file system writable. | ro | | mount the file system read-only. | rw | | mount the file system read-write. | suid | | allow set-user-identifier or set-group-identifier bits to take effect. | sync | | do all I/O to the file system synchronously. | user | | allow an unprivilieged user to mount the file system. This option implies
the options
noexec, nosuid, nodev
unless overridden by subsequent options. |

LSB Deprecated Options
The behaviors specified in this section are expected to
disappear from a future version of the LSB; applications should only
use the non-LSB-deprecated behaviors.
-V | | output version and exit. |
