Hi all,

My batch file script looks like this.

echo test > "path for output file " 2> "C:\test\output.err"

When I run above batch file it fails with error "The system cannot find the path specified." which is fine, however I want to capture this error and send it to C:\test\output.err which is not happening .

This way you are saying to redirect the output of "echo test" to a file, and then redirecting the standard error of that redirection itself to another file.BC_Programmer is right.Started helping the user on destiny about an hour before they posted here.
