Most commands for file system administration have both a generic component and a file system–specific component. Whenever possible, you should use the generic commands, which call the file system–specific component. The following table lists the generic commands for file system administration. These commands are located in the /usr/sbin directory.
Table 16-1 Generic Commands for File System Administration
The generic file system commands determine the file system type by following this sequence:
From the -F option, if supplied.
By matching a special device with an entry in the /etc/vfstab file (if the special device is supplied). For example, fsck first looks for a match against the fsck device field. If no match is found, the command then checks the special device field.
By using the default specified in the /etc/default/fs file for local file systems and in the /etc/dfs/fstypes file for remote file systems.
Both the generic commands and specific commands have manual pages in the man pages section 1M: System Administration Commands. The manual pages for the generic file system commands provide information about generic command options only. The manual page for a specific file system command has information about options for that file system. To look at a manual page for a specific file system, append an underscore and the abbreviation for the file system type to the generic command name.
For example, to see the specific manual page for mounting a UFS file system, type the following:
$ man mount_ufs
For example, to see the specific manual page for mounting a ZFS file system, type the following:
$ man zfs
