How to capture command prompt output and write it to text file

Say you have a batch script that you run that throws back information you want to keep. Well maybe the best way to do that is to have the output written to a text file. This technique can then be combined with a task scheduler so you have an  automated task that creates a log file.

The below batch script below has two main parts. The first part creates a file to capture the command output. The second part is the command prompt command to run.

Creating the file takes the following 2 parameters:

  • filePath: Where you want the file written, defaulted to your desktop
  • baseName: What the file will be called exclusive of a time stamp, defaulted to Output

The script will then take these parameters to create the parameter fileName, which combines the directory location, with what you want the file to be called along with a time stamp, e.g. User\Desktop\Output20170213111157

The command prompt command goes between the parenthesis (). The results of this command will be written to the file.

@ECHO off
REM SET FILE OUTPUT DIRECTORY
SET "filePath=%USERPROFILE%\Desktop\"
REM SET THE BASE OF THE NAME FOR THE OUTPUT FILE 
SET "baseName=Output"
REM CREATE TIMESTAMP
SET timeStamp=%date:~6,8%%date:~3,2%%date:~0,2%%time:~0,2%%time:~3,2%%time:~6,2%
REM CREATE VARIABLE TO HOLD FILENAME WITH A TIMESTAMP
SET "fileNameStamp=%baseName%%Timestamp%"
SET "fileName=%filePath%%fileNameStamp%"
REM CAPTURE COMMAND OUTPUT TO TEXT FILE
> %fileName%.txt (
REM This is where the commands go!
ECHO Text Captured
)

The following working example captures your computer network information and writes it to the file NetworkInfo(time stamp) on your desktop.

@ECHO off
REM SET FILE OUTPUT DIRECTORY
SET "filePath=%USERPROFILE%\Desktop\"
REM SET THE BASE OF THE NAME FOR THE OUTPUT FILE 
SET "baseName=NetworkInfo"
REM CREATE TIMESTAMP
SET timeStamp=%date:~6,8%%date:~3,2%%date:~0,2%%time:~0,2%%time:~3,2%%time:~6,2%
REM CREATE VARIABLE TO HOLD FILENAME WITH A TIMESTAMP
SET "fileNameStamp=%baseName%%Timestamp%"
SET "fileName=%filePath%%fileNameStamp%"
REM CAPTURE COMMAND OUTPUT TO TEXT FILE
> %fileName%.txt (
REM This is where the commands go!
echo Checking your network information, Please wait...

systeminfo | findstr /c:"Host Name" 
systeminfo | findstr /c:"Domain"

ipconfig /all | find "Physical Address" 

ipconfig | find "IPv4" 
ipconfig | find "Default Gateway"
