Here's a common command for bat: m+ [$/Y) S. M1 F

Echo, @, call, pause, REM (tip: Use:: Instead of REM) are some of the most common commands for batch files, and we start with them. (@ R. E. N "l& L (T. N7]

= = = =========== 3 y$ o+ m$ _/P
First, @ is not a command, but rather a special token for the DOS batch, only for masking command-line echo. Here are some special tokens that you might see in a DOS command line or batch:
CR (0D) command line terminator
Escape (1B) ANSI escape character guide
Space (20) commonly used parameter qualifiers/@: z) z& w R6 E D0 @8 g$ r% O
Tab (09); = less commonly used parameter qualifier + G7 O1 h3 L1 D, J) D7 O

\ "\" string delimiter 0 X9 p ' G. R $ \-X7 V7 U

@ command-line echo mask; I5 A r+ Z6 f/e) \

Second,:: indeed can play the role of REM annotation, and more concise and effective; But there are two points to note:) q& p% {M7 T, M1 M
First, in addition to: outside, any of the following: The beginning of the word lines, in the batch is regarded as the label, and directly ignore all the contents thereafter, just to distinguish from the normal marking, we recommend using Goto is not recognized by the label, that is, immediately after a non-alphanumeric special symbol.
Second, unlike REM, the following character lines is not echoed at execution time, regardless of whether the command-line echo is turned on with Echo on, because the command interpreter does not consider him to be a valid command line, and for this point, REM will be more applicable in some cases than:: In addition, REM can be used in Config.sys files.

Echo indicates that the character after this command is displayed # ^/\6 A! w& Z2 H1 Q4 b* T
echo off means that all running commands do not display the command line itself after this statement 0 K1 x7 q& L5 e/j
@ with echo off, but it is added at the front of each command line, indicating that the runtime does not display this line of command line (only affects the current row).
Call calls another batch file (if the batch file is called directly without calling, the current file cannot be returned and subsequent commands for the current file are executed after the batch file is executed). + T; H ^1 J: _* p0 M
Pause running this sentence pauses the execution of the batch and displays the press any key to continue on the screen ... Prompt, waiting for the user to press any key to continue
REM indicates that the word identifier after this command is interpreted as a line (note), not executed, but for future reference (equivalent to comments in the program).
* = = =====
The description here is more confusing than the command line that directly refers to a command helps more coherently: @+ n$ g6 M |; K-u

ECHO

Displays or hides the body of the batch program when the program is running. can also be used to allow or suppress the echoing of commands.

When you run a batch program, MS-DOS typically displays (echoes) commands in the batch program on the screen.
Use the echo command to turn this feature off. 0 ~% P2 ': S3 T8 L4-J
