Today, what the editor shares with you is the detailed explanation of mount commands and common command parameters. I believe many people do not know much about mount commands. In order to let you know more about mount commands, I have summarized the following contents. Let's look down together. I'm sure you'll get something.

Detailed explanation of linux mount command

The mount command is used to load the file system to the specified mount point. This command is also often used to mount cdrom, so that we can access the data in cdrom, because you insert the CD into cdrom, Linux will not automatically mount, you must use the Linux mount command to complete the mount manually.

Under the Linux system, different directories can mount different partitions and disk devices, and its directories and disk partitions are separate and can be combined freely (by mounting).

Different directory data can span different disk partitions or different disk devices

There is no entrance to the disk device by default, and the entrance that cannot access the disk is the mount point.

The essence of mounting is to add an entry to the disk.

Common command parameters for mount

The standard form of the mount command, is mount-t type device dir-l: display a list of loaded file systems;-h: display help and exit;-v: verbose mode, output instruction execution details;-n: load file systems that are not written to the file "/ etc/mtab";-r: load file systems into read-only mode;-a: load all file systems described in file "/ etc/fstab". -t: load file system type supported include: adfs, affs, autofs, cifs, coda, coherent, cramfs, debugfs, devpts, efs, ext, ext2, ext3, ext4, hfs, hfsplus, hpfs, iso9660, jfs, minix, msdos, ncpfs, nfs, nfs4, ntfs, proc, qnx4, ramfs, reiserfs, romfs, squashfs, smbfs, sysv, tmpfs, ubifs, ubifs, udf, ufs, umsdos.
