grammar
mount [-hV] mount -a [-fFnrsvw] [-t vfstype] mount [-fnrsvw] [-o options [,...]] device | dir mount [-fnrsvw] [-t vfstype] [-o options] device dir
Parameter Description:
- -V: Display the program version
- -h: display auxiliary information
- -v: shows a more messages, usually used to debug and -f.
- -a: all file systems / etc / fstab defined hang.
- -F: This command is usually used in conjunction with -a, it will generate an itinerary for each mount responsible for the implementation of the action. When the system needs to mount a large number of NFS file systems can speed up the mount operation.
- -f: commonly used in debugging purposes. It will mount the action does not perform the actual hanging, but simulate the whole process to hang. Usually used in conjunction with -v.
- -n: In general, mount will write a data in / etc / mtab after hanging in. However, in the absence of the system can be written to the file system exists can use this option to cancel this action.
- -sr: equal -o ro
- -w: equal -o rw
- -L: The hard disk partition containing a specific tag hanging.
- -U: The file system partition file number is hanging down. -L And -U there must be meaningful only in the / proc / partition this file.
- -t: Specifies the file system type, usually do not have to be specified. mount will automatically select the correct patterns.
- -o async: Open non-synchronous mode, all files read or write actions are performed using asynchronous mode.
- -o sync: synchronous execution mode.
- -o atime, -o noatime: atime when opened, will be updated each time the file is read "one-call time" file. When we use the flash file system option this option may be turned off to reduce the number of writes.
- -o auto, -o noauto: turn on / off the automatic hang up mode.
- -o defaults: Use the default option rw, suid, dev, exec, auto, nouser, and async.
- -o dev, -o nodev-o exec, -o noexec allows the executable file to be executed.
- -o suid, -o nosuid:
- Allow executable file execution with root privileges.
- -o user, -o nouser: Users can execute mount / umount operation.
- -o remount: a file system has been linked to lower re-hung in different ways. For example, the original system is read-only, read-write mode can now use the re-hang.
- -o ro: read-only mode by hanging.
- -o rw: read-write mode can be used to hang.
- -o loop =: use loop mode is used to partition a hard disk as a file system mount.
Examples
The / dev / hda1 hanging under / mnt.
#mount /dev/hda1 /mnt
The / dev / hda1 hanging under / mnt with a read-only mode.
#mount -o ro /dev/hda1 /mnt
The /tmp/image.iso this disc image file using the hanging loop mode under / mnt / cdrom. In this way the network can be found on ships Linux DVD ISO file can view its contents without burning a CD case.
#mount -o loop /tmp/image.iso /mnt/cdrom
