It means, literally, map file descriptor 2 (stderr) over top of
file descriptor 1 (stdout). If you redirect stdout to a file ( > stdoutfile )
this then maps stderr to the same place that stdout is going, so you
get all the output in one file.
Ex:
foo > foo.out 2> foo.err
Sends stdout from foo to foo.out and stderr to foo.err (not the 2>
notation is the same as 2>&1 - it means do this to fd #2).
foo > foo.out 2>&1
Sends both stdout and stderr to foo.out. The 2> remains the same
but the &1 in place of a file name redirects it to another file descriptor.
