All of the approaches above result in multiple files. One file is for the standard output stream and the other is for the standard error stream. If you want to include both of these outputs to the same file, you can do that too. To do this, you just need to redirect all output to the same file using the following command.

Using the example above, if you only want Standard Output and no Standard Error at all, you can use the following command:. You can perform any of the same output commands above from inside a BAT file and the output from that line will go to the output file you specify. This is a useful way to see whether any commands within a BAT file had any errors when they tried to run.

The standard error can be redirected to the command line or a file using a terminal. If you want to record or store messages in a separate log file or hide the error messages, redirecting stderr will help you.

As redirection is a method of capturing a program output and sending it as an input to another command or file. We will demonstrate different options to redirect stderr as well.
