-i, do not classify the file further than to identify it as either: nonexistent, a block special file, a character special file, a directory, a FIFO, a socket, a symbolic link, or a regular file. Linux [6] and BSD [7] systems behave differently with this option and instead output an Internet media type ("MIME type") identifying the recognized ...
The Linux console (and Linux virtual consoles) are implemented by the VT (virtual terminal) subsystem of the Linux kernel, and do not rely on any user space software. [3] This is in contrast to a terminal emulator , which is a user space process that emulates a terminal, and is typically used in a graphical display environment.
Some Linux distributions (e.g. Debian) do not have a tmpfs mounted on /tmp by default; in this case, files under /tmp will be stored in the same file system as /. And on almost all Linux distributions, a tmpfs is mounted on /run/ or /var/run/ to store temporary run-time files such as PID files and Unix domain sockets .
Computer programming portal; Linux portal; io_uring [a] (previously known as aioring) is a Linux kernel system call interface for storage device asynchronous I/O operations addressing performance issues with similar interfaces provided by functions like read()/write() or aio_read()/aio_write() etc. for operations on data accessed by file descriptors.
Btrfs is intended to address the lack of pooling, snapshots, integrity checking, data scrubbing, and integral multi-device spanning in Linux file systems. [9] Mason, the principal Btrfs author, stated that its goal was "to let [Linux] scale for the storage that will be available.
A common example is file handling: a file is a representation of information stored on a permanent storage device. The kernel may be able to perform many different operations, including read, write, delete or execute, but a user-level application may only be permitted to perform some of these operations (e.g., it may only be allowed to read the ...

MS-DOS managed hardware device contention (see terminate-and-stay-resident program) by making each device file exclusive open. An application attempting to access a device already in use would discover itself unable to open the device file node. A variety of device driver semantics are implemented in Unix and Linux concerning concurrent access. [4]
