## Name
|
|
|
|
mount - mount a filesystem
|
|
|
|
## Synopsis
|
|
|
|
```**sh
|
|
$ mount
|
|
# mount -a
|
|
# mount <source> <target> [-t fstype] [-o options]
|
|
```
|
|
|
|
## Description
|
|
|
|
If invoked without any arguments, `mount` prints a list of all currently mounted
|
|
filesystems.
|
|
|
|
If invoked as `mount -a`, `mount` mounts all the filesystems configured in
|
|
`/etc/fstab`. This is normally done on system startup by
|
|
[`SystemServer`(7)](../man7/SystemServer.md).
|
|
|
|
Otherwise, `mount` performs a single filesystem mount. Source should be a path
|
|
to a file containing the filesystem image. Target and fstype have the same
|
|
meaning as in the [`mount`(2)](../man2/mount.md) syscall (if not specified,
|
|
fstype defaults to `ext2`).
|
|
|
|
A special source value "none" is recognized, in which case
|
|
[`mount`(8)](mount.md) will not attempt to open the source as a file, and will
|
|
pass an invalid file descriptor to [`mount`(2)](../man2/mount.md). This is
|
|
useful for mounting pseudo filesystems.
|
|
|
|
Options correspond to the mount flags, and should be specified as a
|
|
comma-separated list of flag names (lowercase and without the `MS_` prefix).
|
|
Additionally, the name `defaults` is accepted and ignored.
|
|
|
|
## Files
|
|
|
|
* `/etc/fstab` - read by `mount -a` on startup to find out which filesystems to mount.
|
|
* `/proc/df` - read by `mount` to get information about mounted filesystems.
|
|
|
|
## Examples
|
|
|
|
```sh
|
|
# mount devpts /dev/pts -t devpts -o noexec,nosuid
|
|
# mount /home/anon/myfile.txt /tmp/foo -o bind
|
|
```
