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 file because it is being used by another process.
Is it possible, or should I just redirect to two separate files?
Answer
You want:
dir > a.txt 2>&1
The syntax 2>&1
will redirect 2
(stderr) to 1
(stdout). You can also hide messages by redirecting to NUL
, more explanation and examples on MSDN.
