Redirecting Output from within Batch file
74
I am creating a batch file with some simple commands to gather information from a system. The batch file contains commands to get the time, IP information, users, etc.
I assembled all the commands in a batch file, and it runs, but I would like the batch file, when run to output the results to a text file (log). Is there a command that I can add to the batch that would do so?
Keep in mind I do not want to run the batch from cmd, then redirect output ; I want to redirect the output from inside the batch, if that is possible.

The simple naive way that is slow because it opens and positions the file pointer to End-Of-File multiple times.
@echo off
command1 >output.txt
command2 >>output.txt
...
commandN >>output.txt
A better way - easier to write, and faster because the file is opened and positioned only once.
@echo off
>output.txt (
command1
command2
...
commandN
)
Another good and fast way that only opens and positions the file once
@echo off
call :sub >output.txt
exit /b
:sub
command1
command2
...
commandN

Note that the call solution changes your %0 (to sub in this case) which may or may not be what you want.

@Jannes - True, but you can always get info about the running batch script if you add a modifier. For example,%~f0always gives the full path to the batch script, even when inside a CALLed :subroutine.

@Moondra - that is standard batch syntax for calling a labeled subroutine within the same script. Executecmd /?orhelp cmdfrom the console command line for documentation. The trick of the third method is that the redirection on the CALL applies to all commands within the CALLed subroutine.

I know this is an older post, but someone will stumble across it in a Google search and it also looks like some questions the OP asked in comments weren't specifically addressed. Also, please go easy on me since this is my first answer posted on SO. :)
To redirect the output to a file using a dynamically generated file name, my go-to (read: quick & dirty) approach is the second solution offered by @dbenham. So for example, this:
@echo off
> filename_prefix-%DATE:~-4%-%DATE:~4,2%-%DATE:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.log (
echo Your Name Here
echo Beginning Date/Time: %DATE:~-4%-%DATE:~4,2%-%DATE:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.log
REM do some stuff here
echo Your Name Here
echo Ending Date/Time: %DATE:~-4%-%DATE:~4,2%-%DATE:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.log
)
Will create a file like what you see in this screenshot of the file in the target directory
That will contain this output:
Your Name Here
Beginning Date/Time: 2016-09-16_141048.log
Your Name Here
Ending Date/Time: 2016-09-16_141048.log
Also keep in mind that this solution is locale-dependent, so be careful how/when you use it.

Thanks this was useful. Quick question is there a reason why you are using .log vs .txt? Does that make a difference?

@Moondra no it doesn't. It's just semantics in this case. That's not to say there aren't applications that require/grep based on file type, so just be aware of if/how your files are being used.

echo some output >"your logfile"
or
(
echo some output
echo more output
)>"Your logfile"
should fill the bill.
If you want to APPEND the output, use >> instead of >. > will start a new logfile.

There is a cool little program you can use to redirect the output to a file and the console
some_command ^| TEE.BAT [ -a ] filename
@ECHO OFF
:: Check Windows version
IF NOT "%OS%"=="Windows_NT" GOTO Syntax
:: Keep variables local
SETLOCAL
:: Check command line arguments
SET Append=0
IF /I [%1]==[-a] (
SET Append=1
SHIFT
)
IF [%1]== GOTO Syntax
IF NOT [%2]== GOTO Syntax
:: Test for invalid wildcards
SET Counter=0
FOR /F %%A IN ('DIR /A /B %1 2^>NUL') DO CALL :Count "%%~fA"
IF %Counter% GTR 1 (
SET Counter=
GOTO Syntax
)
:: A valid filename seems to have been specified
SET File=%1
:: Check if a directory with the specified name exists
DIR /AD %File% >NUL 2>NUL
IF NOT ERRORLEVEL 1 (
SET File=
GOTO Syntax
)
:: Specify /Y switch for Windows 2000 / XP COPY command
SET Y=
VER | FIND "Windows NT" > NUL
IF ERRORLEVEL 1 SET Y=/Y
:: Flush existing file or create new one if -a wasn't specified
IF %Append%==0 (COPY %Y% NUL %File% > NUL 2>&1)
:: Actual TEE
FOR /F "tokens=1* delims=]" %%A IN ('FIND /N /V ""') DO (
> CON ECHO.%%B
>> %File% ECHO.%%B
)
:: Done
ENDLOCAL
GOTO:EOF
:Count
SET /A Counter += 1
SET File=%1
GOTO:EOF
:Syntax
ECHO.
ECHO Tee.bat, Version 2.11a for Windows NT 4 / 2000 / XP
ECHO Display text on screen and redirect it to a file simultaneously
ECHO.
IF NOT "%OS%"=="Windows_NT" ECHO Usage: some_command ³ TEE.BAT [ -a ] filename
IF NOT "%OS%"=="Windows_NT" GOTO Skip
ECHO Usage: some_command ^| TEE.BAT [ -a ] filename
:Skip
ECHO.
ECHO Where: "some_command" is the command whose output should be redirected
ECHO "filename" is the file the output should be redirected to
ECHO -a appends the output of the command to the file,
ECHO rather than overwriting the file
ECHO.

@echo OFF
[your command] >> [Your log file name].txt
I used the command above in my batch file and it works. In the log file, it shows the results of my command.

Add these two lines near the top of your batch file, all stdout and stderr after will be redirected to log.txt:
if not "%1"=="STDOUT_TO_FILE" %0 STDOUT_TO_FILE %* >log.txt 2>&1
shift /1

This worked for me, thanks. Any special considerations where this may fail? (e.g. output size overflow)

+1. It's also worth pointing out that using
>> will append to a.txt. To overwrite a.txt instead, use >. stackoverflow.com/q/4458231/1098302– Aaron

I know this is an older post, but someone will stumble across it in a Google search and it also looks like some questions the OP asked in comments weren't specifically addressed. Also, please go easy on me since this is my first answer posted on SO. :)
To redirect the output to a file using a dynamically generated file name, my go-to (read: quick & dirty) approach is the second solution offered by @dbenham. So for example, this:
@echo off
> filename_prefix-%DATE:~-4%-%DATE:~4,2%-%DATE:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.log (
echo Your Name Here
echo Beginning Date/Time: %DATE:~-4%-%DATE:~4,2%-%DATE:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.log
REM do some stuff here
echo Your Name Here
echo Ending Date/Time: %DATE:~-4%-%DATE:~4,2%-%DATE:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%.log
)
Will create a file like what you see in this screenshot of the file in the target directory
That will contain this output:
Your Name Here
Beginning Date/Time: 2016-09-16_141048.log
Your Name Here
Ending Date/Time: 2016-09-16_141048.log
Also keep in mind that this solution is locale-dependent, so be careful how/when you use it.

Thanks this was useful. Quick question is there a reason why you are using .log vs .txt? Does that make a difference?

@Moondra no it doesn't. It's just semantics in this case. That's not to say there aren't applications that require/grep based on file type, so just be aware of if/how your files are being used.

Add these two lines near the top of your batch file, all stdout and stderr after will be redirected to log.txt:
if not "%1"=="STDOUT_TO_FILE" %0 STDOUT_TO_FILE %* >log.txt 2>&1
shift /1
