in thread Writing the output of test::more in to another file

You can read more about that in Bash Guide for Beginners, chapter 9. Here's a quote from that document that explains "1" and "2": Each open file gets assigned a file descriptor. The file descriptors for stdin, stdout, and stderr are 0, 1, and 2, respectively.

So "2>&1" means: redirect stderr to stdout. See more examples in the guide.
