简介
配置文件 /etc/fstab 包含了 挂载 磁盘的必需信息。该文件系统启动时开始读入，并且仅能被 root 用户修改。
Content of file
It is possible to visualize this file with the following command:
cat /etc/fstab
or alt-f2 and enter:
gksu gedit /etc/fstab
The result of the previous command will be similar to following:
# /etc/fstab: static file system information. # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc defaults 0 0 # /dev/hda1 UUID=12102C02102CEB83 /media/windows ntfs silent,umask=0,locale=it_IT.utf8 0 0 # /dev/hda2 UUID=cee15eca-5b2e-48ad-9735-eae5ac14bc90 none swap sw 0 0 # /dev/hda3 UUID=98E0-6D24 /media/dati vfat defaults,utf8,umask=007,uid=0,gid=46,auto,rw,nouser 0 0 # /dev/hda4 UUID=0aa86c61-0df9-4f1a-8b0b-34abbee6b769 / ext3 nouser,defaults,errors=remount-ro,atime,auto,rw,dev,exec,suid 0 0 /dev/hdc /media/cdrom0 udf,iso9660 user,atime,noauto,rw,dev,exec,suid 0 0
Each no-commented line is composed by six fields:
| fields | description |
| file system | it indicates the devices that contain a file system |
| mount point | it indicates the directory (or mount point) from which it will be possible to approach the content of the device (for the swap is not demanded the mount point) |
| type | type of file system |
| options | options of access to device (the command "mount") |
| dump | turn ON/OFF the backup of file system (the command "dump"). This option is obsolete. |
| pass | turn ON/OFF the control of coherence of the disc (the command "fsck") |
To get a list of all the UUID's use this command:
ls -l /dev/disk/by-uuid
