In computing, ren (or rename) is a command in various command-line interpreters such as COMMAND.COM, cmd.exe, 4DOS, 4NT and Windows PowerShell. It is used to rename computer files and in some implementations (such as AmigaDOS [1]) also directories. It is analogous to the Unix mv command.
In computing, rename refers to the altering of a name of a file. This can be done manually by using a shell command such as ren or mv , or by using batch renaming software that can automate the renaming process.
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.
IF is a conditional statement, that allows branching of the program execution. It evaluates the specified condition, and only if it is true, then it executes the remainder of the command line. Otherwise, it skips the remainder of the line and continues with next command line. Used in Batch files.
The Bash command syntax is a superset of the Bourne shell command syntax. Bash supports brace expansion, [80] command line completion (Programmable Completion), [81] basic debugging [82] [83] and signal handling (using trap) since bash 2.05a [84] [85] among other features.

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 ...
A Unix shell is a command-line interpreter or shell that provides a command line user interface for Unix-like operating systems. The shell is both an interactive command language and a scripting language , and is used by the operating system to control the execution of the system using shell scripts .
