ECHO ON was chosen as the default setting when interpreting batch files to preserve backwards compatibility. In PC-DOS 1.0, COMMAND.COM displayed each command as it interpreted it, and this couldn’t be disabled. ECHO was added in PC/MS-DOS 2.0, with a dual purpose (displaying messages, and controlling the display of batch file commands); its default is ON so that the behaviour of batch files written for DOS 1.0 doesn’t change.Dosyanın başına @echo off yazılır. Böylece komutların çıktısı ekranda görünmez.

A pseudo environment variable named errorlevel stores the exit code:Örnek
@echo off
my_nify_exe.exe
if %ERRORLEVEL% EQU 0 (
echo Success
) else (
echo Failure Reason Given is %errorlevel%
exit /b %errorlevel%
)
Be careful however as setting and using variables inside of a loop may require delayed expansion
The tilde (~) sign is used in different ways in batch files:- Argument quote removal. A tilde sign before an command-line argument (such as "%~1") indicates to remove the surrounding quotes from the parameter. Such if the value for %1 is "Hi" then %~1 will expand to only Hi.- Substring processing. There is a way to extract substring from a string variable in batch file. The syntax is: %variable:~num_chars_skip,num_chars_keep%. Num chars skip means the point where to start in the string, or to exclude how much characters preceding the string variable. And num chars to keep indicates the number of characters after the start point. Num chars to keep is optional, but first is mandatory. If num chars to keep is not specified, only that num chars to keep'th character will be parsed.

- The magic variables %n contains the arguments used to invoke the file:- %0 is the path to the bat-file itself- %1 is the first argument after, %2 is the second and so on.Since the arguments are often file paths, there is some additional syntax to extract parts of the path.- ~d is drive- ~p is the path (without drive),- ~n is the file name. They can be combined so ~dp is drive+path.- %~dp0 is therefore pretty useful in a bat: it is the folder in which the executing bat file resides.You can also get other kinds of meta info about the file:- ~t is the timestamp,- ~z is the size.

The @ symbol tells the command processor to be less verbose; to only show the output of the command without showing it being executed or any prompts associated with the execution. When used it is prepended to the beginning of the command, it is not necessary to leave a space between the "@" and the command.When "echo" is set to "off" it is not necessary to use "@" because setting "echo" to "off" causes this behavior to become automatic. "Echo" is usually set to "on" by default when the execution of a script begins. This is the reason "@echo off" is commonly used, to turn echo off without displaying the act of turning it off.

Calls one batch program from another, calls a subprogram within a single batch program, or, as an undocumented behavior, starts a program. In particular, suspends the execution of the caller, starts executing the callee, and resumes the execution of the caller if and when the callee finishes execution.Örnek
...
Beware that calling a batch program from a batch without using the call keyword results in the execution never returning to the caller once the callee finishes.
The callee inherits environment variables of the caller, and unless the callee prevents that via SETLOCAL, changes made by the callee to environment variables become visible to the caller once it resumes execution.
