The reason why you'd sometimes want to consult /etc/mtab in preference to or in addition to /proc/mounts is that because it has access to the mount command line, it's sometimes able to present information in a way that's easier to understand for example you see mount options as requested (whereas /proc/mounts lists the mount and kernel defaults as well), and bind mounts appear as such in /etc/mtab.Īs of v. Any file with some invariant identifier at a small fixed offset into the file can usually be described in this way. Actions performed while /etc/mtab is on a read-only filesystem are also not recorded there. Also, mounts performed in the chroot will be reflected in the chroot's /etc/mtab but not in the main /etc/mtab. In practice, it's mostly in a chroot that you'll find /etc/mtab files that differ wildly from the state of the system. That means that if you don't use these commands (which is pretty rare), your action (mount or unmount) won't be recorded. This list is maintained by the mount and umount commands. There's also a list of mounted filesystems in /etc/mtab. ( There are ways to escape the chroot, mind.) For example, in a chroot, /proc/mounts lists only the filesystems whose mount point is within the chroot. If you have any form of containers on your system, /proc/mounts only lists the filesystems that are in your present container. We can see the two folders on the Raspberry Pi called dave and pat.The definitive list of mounted filesystems is in /proc/mounts. You must create your mount point in advance.īy accessing our mount point at /media/dave/NAS we are accessing the shared directory on the Raspberry Pi across the network. /media/dave/NAS: The name of the mount point.The root of the share is a directory called Backup, but its Samba share name is set to share. ![]() ![]() //192.168.4.13/share: The network location of the device with the Samba share on it, and the Samba name of the shared directory.-o credentials=/etc/samba/creds,uid=1000,gid=1000: The options parameters are the path to a file called creds that is secured and contains the user name and password for the Raspberry Pi user the User ID (UID) and Group ID (GID) that are used to set the owner and group of the root of the file system.Let’s break down the parts of that command. The df command can also be used to display which file systems are mounted and where their mount points are.ĭf used with no parameters gives you the same information overload problem as mount. As an example, in Ubuntu Linux, there is a squashfs pseudo-file system created for each and every application that has been installed using the snap command. Who wants to see all of those? RELATED: Which Linux File System Should You Use? Interrogate Your File System With df ![]() errors=remount -o: If a sufficiently serious error is detected, the file system will be remounted in read-only mode to allow diagnosis. You can do this on command line, using the -R switch (recursive) and then piping the output to a file thus: ls -R > filename1 this will make a file called filename1 in the current directory, containing a full directory listing of the current directory and all of the sub-directories under it.relatime: The kernel is using an optimized scheme to record file access and modification meta-data.rw: The file system is readable and writable.On this test computer, there is a single ext4 file system, it is on device sda-the first storage device mounted, usually the main hard drive-and mounted on /, which is the root of the file system tree. We’ve also issued a command to list ext4 file systems. ![]()
