Mounting Volumes, Unmounting Volumes

Mounting Volumes

You can use the mount tool with parameters appropriate to the type of file system you want to mount, or use one of these file-system–specific mount commands:

Âmount_afp for Apple File Protocol (AppleShare) volumes

Âmount_cd9660 for ISO 9660 volumes

Âmount_cddafs for CD Digital Audio format (CDDA) volumes

Âmount_hfs for Apple Hierarchical File System (HFS) volumes

Âmount_msdos for PC MS-DOS volumes

Âmount_nfs for Network File System (NFS) volumes

Âmount_smbfs for Server Message Block (SMB/CIFS) volumes

Âmount_udf for Universal Disk Format (UDF) volumes

Âmount_webdav for Web-based Distributed Authoring and Versioning (WebDAV) volumes

mount prepares and grafts a special device or the remote node (rhost:path) on to the file system tree at the point node. See the related man pages for more information.

To view a list of currently mounted file systems:

$ sudo mount

To mount a network folder:

$ mount /dev/

mount returns the value 0 if the mount succeeded.

Unmounting Volumes

You can use the umount tool to unmount a volume. umount removes a special device or the remote node (rhost:path) from the file system tree at the point node.

To unmount a volume:

$ umount

umount returns the value 0 if the umount succeeded. See the umount man page for more information.
