Everything you wanted to know about Echo but was afraid to ask!
Display messages on screen, turn command-echoing on or off.
Syntax ECHO [ON | OFF] ECHO [message] 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
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 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 ^ as follows:
ECHO Nice ^&Easy ECHO Salary is ^> Commision ECHO Name ^| Username ^| Expiry Date ECHO:Off On Holiday
Echo text into a FILE
The general syntax is
Echo This is some Text > FileName.txt
or if you want to avoid extra spaces:
Echo Some more text>FileName.txt
Append text into an existing FILE
(use >> instead of >)
Echo This is some Text >> FileName.txt
Echo a Variable
To display a department variable:
An alternative is to separate with : instead of a space, this has some performance benefits.
If the variable does not exist – ECHO will simply return the text “%_department%”
Echo a file
Use the TYPE command.
Echo a sound
The following command in a batch file will trigger the default beep on most PC’s
Alternatively using Windows Media Player:
START/min wmplayer.exe %windir%\media\ding.wav
(In Windows XP use sndrec32.exe or mplay32.exe)
Echo a blank line
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 this file does not exist the command does work, but this makes it slower than echo(
To ECHO text without including a CR/LF (source)
<nul (set/p _any_variable=string to emit)
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
Echo Text_String > FileName:StreamName
Only the following commands support the File:Stream syntax – ECHO, MORE, FOR
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.
