Log output from unrar.exe to a text file (Batch script)

I开发者_如何学JAVA am writing a batch script that extracts files and would now like to log the output from unrar.exe to a text file. The output I have in mind are things like failure due to corrupted archives etc. or simply that the operation was successful.

Any ideas on how to solve this?

Thanks in advance!

You use redirection:

unrar > logfile.txt

To also redirect stderr:

unrar > logfile.txt 2>&1

Just the STDOUT

unrar>"output.txt"

Only the errors (ERROUT)

unrar 2>"errors.txt"

Both STDOUT and ERROUT

unrar 2>&1 "both.txt"

Or both in separate files:

unrar 2>"errors.txt" >"output.txt"
