cp is a shell command for copying files and directories.
If the user has write access to a target file, the command copies the content by opening it in update mode. This preserves the file's inode instead of creating a new file with default permissions.
The command was part of Version 1 Unix,[1] and is specified by POSIX. The implementation from GNU has many additional options beyond the POSIX specification.[2] The command is bundled in GNU Core Utilities[3] and is available in the EFI shell.[4]
