Comment 3 for bug 272921

From Launchpad:

In Windows, the COPY command run in a command prompt allows users to concatenate files by using a plus ("+") operator, for example:

copy file1+file2 outfile

In wine's cmd.exe, it seems to read file1+file2 as a single path and therefore outputs a "Path Not Found". Also, it does not recognize the "con" keyword used to represent stdout/stdin. Therefore another method of concatenating files:

copy file1 outfile
copy file2 con >> outfile

does not work either.

My Ubuntu version is 8.04, AMD64 architecture, though I have seen the same issue on the x86 version as well.
