Redirect Windows cmd stdout and stderr to a single file

Question

I\'m trying to redirect all output (stdout + stderr) of a DOS command to a single file:

C:\\>dir 1> a.txt 2> a.txt
The process cannot access the fil         


        

Answer 1

There is, however, no guarantee that the output of SDTOUT and STDERR are interweaved line-by-line in timely order, using the POSIX redirect merge syntax.

If an application uses buffered output, it may happen that the text of one stream is inserted in the other at a buffer boundary, which may appear in the middle of a text line.

A dedicated console output logger (I.e. the "StdOut/StdErr Logger" by 'LoRd MuldeR') may be more reliable for such a task.
