A file descriptor is the unix abstraction for an open input/output stream: Moves the file descriptor digit to file descriptor n, or the standard input (file descriptor 0) if n is not specified. File descriptors are positive integers that act as abstract handles for io/resources and files. 9 are for additional files. Exec m>&n redirects a file descriptor to another one for the remainder of. Another, simpler use case is filtering the error output of a command. Digit is closed after being dupli‐cated. Examples of file descriptors include.

A file, a network connection, a pipe (a communication channel between processes), a terminal, etc. A file descriptor is a positive integer that acts as a unique identifier (or handle) for “files” and other i/o resources, such as pipes, sockets, blocks, devices, or terminal i/o.
