Mount /dev/foo /dir If you want to override mount options from /etc/fstab you have to use: The mount program does not read the /etc/fstab file if device (or LABEL/UUID) and dir are specified.

The programs mount and umount maintain a list of currently mounted filesystems in the file /etc/mtab. When mounting a filesystem mentioned in fstab or mtab, it suffices to give only the device, or only the mount point. Adding the -F option will make mount fork, so that the filesystems Mounted as indicated, except for those whose line contains the noauto keyword. (usually given in a bootscript) causes all filesystems mentioned in fstab (of the proper type and/or having or not having the proper options) to be The file /etc/fstab (see fstab(5)), may contain lines describing what devices are usually mounted where, using which options. The /etc/fstab, /etc/mtab and /proc/mounts files. (The customary choice none is less fortunate: the error message 'none busy' from umount can be confusing.) The proc filesystem is not associated with a special device, and when mounting it, an arbitrary keyword, such as proc can be used instead of aĭevice specification. The mount(8) command internally uses udev symlinks, so use the symlinks in /etc/fstab is not advantage The tags are more readable, robust and portable. The recommended setup is to use LABEL= or UUID= tags rather than /dev/disk/by- udev symlinks in the /etc/fstabįile. It is possible to indicate a block special device using its volume LABEL or

For example, in the case ofĪn NFS mount, device may look like :/dir. Most devices are indicated by a file name (of a block special device), like /dev/sda1, but there are other possibilities. The option -l adds the labels in this listing. Lists all mounted filesystems (of type type). Three forms of invocation do not actually mount anything: The previous contents (ifĪny) and owner and mode of dir become invisible, and as long as this filesystem remains mounted, the pathname dir refers to the root of the Mount -t type device dir This tells the kernel to attach the filesystem found on device (which is of type type) at the directory dir. The standard form of the mount command, is The mount command serves to attach the filesystem found on some device to the big file tree. These files can be spread out over severalĭevices. All files accessible in a Unix system are arranged in one big tree, the file hierarchy, rooted at /.
