Working with Filesystems The majority of your filesystem-level tasks can be accomplished from directly within YaST. If necessary, these same tasks can be accomplished from the command line using the tools in Table A.14. Table A.14. Commands Used to Create and Manage Filesystems COMMAND GENERAL USAGE DESCRIPTION df df [OPTIONS] Displays disk usage statistics for all mounted filesystems. Common options include -h Return output in human readable form du du [OPTIONS] [PATH] Displays disk usage statistics for the specified path. Common options include -h Return output in human readable form -s Provide a summary of the specified directory fdisk fdisk DEVICE Used to modify the partition table for fixed disks. fsck fsck [OPTIONS] PARTITION Utility used to check and repair a Linux filesystem. This utility should be used with care and after ensuring that appropriate backup measures have been taken. Common options include -a Automatically repair the filesystem -r Interactively perform the repair operation -V Produce verbose output of the operation For information on advanced repair options for fsck, including filesystem-specific options, see man fsck. fuser fuser [OPTIONS] PATH Used to identify users or processes currently using a specific filesystem. Common options include -u Display user ids mkfs mkfs [OPTIONS] PARTITION Formats a partition with the specified filesystem type. mount mount [OPTIONS] DEVICE MOUNT_POINT Associates the specified device with a directory in the root filesystem structure. This is used to gain access to hard disk partitions and physical devices such as CD-ROMs. Common options include -t Filesystem type (ext2, reiserfs, iso9660, and so on) -o Filesystem-specific options (For information on filesystem- specific mount options, see man mount.) umount umount MOUNT_POINT Unmounts the device currently ounted at the specified directory.
