Display messages on screen, turn command-echoing on or off.
Syntax ECHO [ON | OFF] ECHO [message] ECHO /? Key ON : Display each line of the batch on screen (default) OFF : Only display the command output on screen message : a string of characters to display ? : Display help
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.
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:
ECHO Nice ^&Easy ECHO Salary is ^> Commision ECHO Name ^| Username ^| Expiry Date ECHO:Off On Holiday ECHO: /? Will display help
The general syntax is:
Echo This is some Text > FileName.txt
To avoid extra spaces:
Echo Some more text>FileName.txt
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
Will will actually turn Echo off
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.
Use the TYPE command.
The following command in a batch file will trigger the default beep on most PC'sECHO ^G
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
The following in a batch file will produce an empty line:
The second option is better, 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:
To ECHO text without including a CR/LF (source)
<nul (set/p _any_variable=string to emit)
Streams allow one file to contain several separate forks of information (like the macintosh resource fork)
The general syntax is:
Echo Text_String > FileName:StreamName
Only the following commands support the File:Stream syntax - ECHO, MORE, FOR
Creating streams:Echo This is stream1 > myfile.dat:stream1 Echo This is stream2 > myfile.dat:stream2
More < myfile.dat:stream1 More < myfile.dat:stream2 FOR /f "delims=*" %%G in (myfile.dat:stream1) DO echo %%G FOR /f "delims=*" %%G in (myfile.dat:stream2) DO echo %%G
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.
