mount Command Cheatsheet

The mount command in Unix-like systems is used to mount filesystems and network shares onto the directory tree. It is essential for managing storage devices and network shares efficiently. Here’s a quick reference guide:

Basic Syntax

mount [OPTION]... [DEVICE] [DIRECTORY]

Common Options

• -t TYPE, --types TYPE: Specify the filesystem type (e.g., ext4, nfs).

    mount -t ext4 /dev/sdb1 /mnt/data
  

• -o OPTIONS, --options OPTIONS: Mount options (e.g., rw for read-write, ro for read-only).

    mount -o rw /dev/sdb1 /mnt/data
  

• -a, --all: Mount all filesystems listed in /etc/fstab (except noauto entries).

    mount -a
  

• -r, --read-only: Mount the filesystem read-only.

    mount -o ro /dev/sdb1 /mnt/data
  

• -v, --verbose: Verbose mode, print detailed information during the mount operation.

    mount -v /dev/sdb1 /mnt/data
  

Examples

1. Mount a device to a directory:

    mount /dev/sdb1 /mnt/data
   

2. Mount a filesystem specifying type and options:

    mount -t ext4 -o rw /dev/sdb1 /mnt/data
   

3. Mount all filesystems listed in /etc/fstab:

    mount -a
   

4. Mount a remote NFS share:

    mount -t nfs server:/share /mnt/nfs
   

5. Unmount a mounted filesystem:

    umount /mnt/data
   

Additional Information

• List mounted filesystems:

    mount
  

• Help option:

    mount --help
  

• View manual page for mount:

    man mount
  

The mount command is crucial for managing filesystems and network shares in Unix-like systems. It allows administrators to control storage devices and network resources effectively. For more detailed options and usage scenarios, refer to the man page or use mount --help.
