fstab (after file systems table) is a system file commonly found in the directory /etc on Unix and Unix-like computer systems. In Linux, it is part of the util-linux package. The fstab file typically lists all available disk partitions and other types of file systems and data sources that may not necessarily be disk-based, and indicates how they are to be initialized or otherwise integrated ...
This file lists all currently mounted filesystems along with their initialization options. mtab has a lot in common with fstab, the distinction being that the latter is a configuration file listing which available filesystems should be mounted on which mount points at boot time, whereas the former lists currently mounted ones, which can include manually mounted ones not listed in fstab.
This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.
In computing, mount is a command in various operating systems. Before a user can access a file on a Unix-like machine, the file system on the device [1] which contains the file needs to be mounted with the mount command. Frequently mount is used for SD card, USB storage, DVD and other removable storage devices.
The directory given to the operating system is called the mount point – it might, for example, be /media. The /media directory exists on many Unix systems (as specified in the Filesystem Hierarchy Standard) and is intended specifically for use as a mount point for removable media such as CDs, DVDs, USB drives or floppy disks. It may be empty ...
The read permission grants the ability to read a file. When set for a directory, this permission grants the ability to read the names of files in the directory, but not to find out any further information about them such as contents, file type, size, ownership, permissions. The write permission grants the ability to modify a file. When set for ...
In the Linux kernel, the fat, hfs, hpfs, ntfs, and udf file system drivers support a umask mount option, which controls how the disk information is mapped to permissions. This is not the same as the per-process mask described above, although the permissions are calculated in a similar way.
The Unix and Linux access rights flags setuid and setgid (short for set user identity and set group identity) [1] allow users to run an executable with the file system permissions of the executable's owner or group respectively and to change behaviour in directories. They are often used to allow users on a computer system to run programs with ...
