Комментарии Remarks

echo Команда особенно полезна при отключенном эхо . The echo command is particularly useful when echo is turned off. Чтобы отобразить сообщение, которое содержит несколько строк без отображения команд, можно включить несколько echo команд после команды echo off в пакетной программе. To display a message that is several lines long without displaying any commands, you can include several echo commands after the echo off command in your batch program.

После выключения эхо Командная строка не отображается в окне командной строки. After echo is turned off, the command prompt doesn’t appear in the Command Prompt window. Чтобы отобразить командную строку, введите команду echo on. To display the command prompt, type echo on.

Если используется в пакетном файле, Включение и вывод не влияют на параметр в командной строке. If used in a batch file, echo on and echo off don’t affect the setting at the command prompt.

Чтобы предотвратить вывод определенной команды в пакетном файле, вставьте @ знак перед командой. To prevent echoing a particular command in a batch file, insert an @ sign in front of the command. Чтобы предотвратить вывод всех команд в пакетном файле, включите команду echo off в начале файла. To prevent echoing all commands in a batch file, include the echo off command at the beginning of the file.

Чтобы отобразить символ канала ( | ) или перенаправления ( или > ) при использовании эха, используйте знак крышки ( ^ ) непосредственно перед символом канала или перенаправления. To display a pipe ( | ) or redirection character ( or > ) when you are using echo, use a caret ( ^ ) immediately before the pipe or redirection character. Например,, ^| ^> или ^ ). For example, ^| , ^> , or ^ ). Чтобы отобразить курсор, введите две крышки подряд ( ^^ ). To display a caret, type two carets in succession ( ^^ ).

Примеры Examples

Чтобы отобразить текущее значение echo , введите: To display the current echo setting, type:

Чтобы вывести на экран пустую строку, введите: To echo a blank line on the screen, type:

Не включайте пробел перед точкой. Don’t include a space before the period. В противном случае вместо пустой строки отображается точка. Otherwise, the period appears instead of a blank line.

Чтобы запретить вывод команд в командной строке, введите: To prevent echoing commands at the command prompt, type:

Когда эхо отключено, Командная строка не отображается в окне командной строки. When echo is turned off, the command prompt doesn’t appear in the Command Prompt window. Чтобы снова отобразить командную строку, введите команду echo on. To display the command prompt again, type echo on.

What is echo command in windows

Display messages on screen, turn command-echoing on or off.

Type ECHO without parameters to display the current echo setting (ON or OFF).

In most batch files you will want ECHO OFF, turning it ON can be useful when debugging a problematic batch script.

In a batch file, the @ symbol at the start of a line is the same as ECHO OFF applied to the current line only.

Normally a command is executed and takes effect from the next line onwards, @ is a rare example of a command that takes effect immediately.

Escape Command characters

Command characters will normally take precedence over the ECHO statement
e.g. The redirection and pipe characters: & | ON OFF

To override this behaviour you can escape each command character with ^ or : as follows:

An alternative approach is to use SET /P which will display the string without interpreting anything.

Echo text into a FILE

The general syntax is:
Echo This is some Text > FileName.txt

To avoid extra spaces:
Echo Some more text>FileName.txt

To create an empty (zero byte) file:
Echo. 2>EmptyFile.txt

Echo a Variable

To display a department variable:

A more robust alternative is to separate with : instead of a space.

Using a colon like this will sanitise the values ON /OFF /? so for example

Set _var=OFF
Echo %_var%
Will will actually turn Echo off

Echo:%_var%
Will simply display «OFF»

Using Echo: in this way does have some limitations:

• If the variable does not exist, ECHO: will return the variable name» %_var% «
• If you are using DelayedExpansion ( !_var! ) AND the syntax to search and replace parts of a variable or display substrings of a variable, then the Echo: syntax will not work. You can workaround this by using an intermediate variable or just reverting to the default parse time expansion of variables.

Echo a file

Echo a sound

The following command in a batch file will trigger the default beep on most PC’s

To type the BELL character use Ctrl-G or ‘Alt’ key, and 7 on the numeric keypad. (ascii 7)

The default beep is now played through the speakers/audio system, however if you select the ‘No Sounds’ scheme in Contol Panel > Sounds > Change system sounds, then the default beep will not play.

Alternatively using Windows Media Player:
START/min «C:\Program Files\Windows Media Player\wmplayer.exe» %windir%\media\chimes.wav

Echo a blank line

To produce an empty line, (without displaying the echo status) follow the Echo command with a colon or period character:
Echo:
or
Echo.
The last of those options Echo. can be troublesome because Echo. will search for a file named «echo» if the file is found that raises an error. If the ‘echo’ file does not exist then the command does work, but this still makes Echo. slightly slower than echo:
In theory other command delimiters are available but most have buggy side effects when used for this.

To ECHO text without including a CR/LF (source)

Echo text into a stream

Streams allow one file to contain several separate forks of information (like the macintosh resource fork)

The general syntax is:

Only the following commands support the File:Stream syntax — ECHO, MORE, FOR

Displaying streams:

A data stream file can be successfully copied and renamed despite the fact that most applications and commands will report a zero length file. The file size can be calculated from remaining free space. The file must always reside on an NTFS volume.

ECHO does not set or clear the Errorlevel.
ECHO is an internal command.
