mount: command not found
The mount command loads a file system to a specified directory so that it can be accessible to users and applications. You must specify the device to mount as well as the desired mount point.
Syntax
The syntax of the mount command is:
# mount [options] {device name} {mount point} mount Options
You can specify various mount options for a file system. These options are typically included in the fstab file rather than as command-line arguments.
| Option | Used To |
|---|---|
| auto | Specify that the device has to be mounted automatically. |
| noauto | Specify that the device should not be mounted automatically |
| nouser | Specify that only the root user can mount a device or a file system. |
| user | Specify that all users can mount a device or a file system. |
| exec | Allow binaries in a file system to be executed. |
| noexec | Prevent binaries in a file system from being executed. |
| ro | Mount a file system as read-only. |
| rw | Mount a file system with read and write permissions. |
| sync | Specify that input and output operations in a file system should be done synchronously. |
| async | Specify that input and output operations in a file system should be done asynchronously. |
If you encounter below error while running the mount command:

Mount Command Examples
1. To mount a file system:
# mount /dev/sda /support
2. To specify the file system type:
# mount -t nfs 192.168.100.22:/home /home
3. To mount all the file systems from “/etc/fstab”:
# mount -a
4. To do the fake mounting:
# mount -f /dev/sda /support # mount --fake /dev/sda /support
5. To add the labels to the mount points;
# mount -l mymount /support *****
6. To mount without writting into “/etc/mnttab”:
# mount -n /dev/sda /support # mount --no-mtab /dev/sda /support
7. To avoid canonicalize paths:
# mount --no-canonicalize /dev/sdb /support
8. To ignore ignore mount options not supported by file system type:
# mount -s /dev/sdb /support
9. To mount a file system as read only:
# mount -r /dev/sdb /support # mount --read-only /dev/sdb /support
10. To Mount the filesystem read/write:

Notes
By default, the mount command displays a list of media devices currently mounted on the system. However, the newer version of the kernel mounts lots of virtual filesystems for management purposes, besides your standard storage devices. This can make the default output of the mount command very cluttered and confusing. If you know the filesystem type used for your drive partitions, you can filter that out using
$ mount -t ext4
The mount command provides four pieces of information:
- The device filename of the media
- The mount point in the virtual directory where the media is mounted
- The filesystem type
- The access status of the mounted media
