In computing, cp is a command in various Unix and Unix-like operating systems for copying files and directories.The command has three principal modes of operation, expressed by the types of arguments presented to the program for copying a file to another file, one or more files to a directory, or for copying entire directories to another directory.
Files may be copied to device files (e.g. copy letter.txt lpt1 sends the file to the printer on lpt1. copy letter.txt con would output to stdout, like the type command. Note that copy page1.txt+page2.txt book.txt will concatenate the files and output them as book.txt. Which is just like the cat command). It can also copy files between different ...
Primary hierarchy root and root directory of the entire file system hierarchy. /bin: Essential command binaries that need to be available in single-user mode, including to bring up the system or repair it, [3] for all users (e.g., cat, ls, cp). /boot: Boot loader files (e.g., kernels, initrd). /dev
File copying is a fundamental operation for data storage. [citation needed] Most popular operating systems such as Windows, macOS and Linux as well as smartphone operating systems such as Android contain built-in file copying functions as well as command line (CLI) and graphical (GUI) interfaces to filing system copy and move functions. In some ...
dd is a command-line utility for Unix, Plan 9, Inferno, and Unix-like operating systems and beyond, the primary purpose of which is to convert and copy files. [1] On Unix, device drivers for hardware (such as hard disk drives) and special device files (such as /dev/zero and /dev/random) appear in the file system just like normal files; dd can also read and/or write from/to these files ...
When using the mv command on files located on the same filesystem, the file's timestamp is not updated. On UNIX implementations derived from AT&T UNIX, cp, ln and mv are implemented as a single program with hard-linked binaries. The behavior is selected from the path name argv[0]. This is a common technique by which closely related commands ...
