The '2>&1' part is shell syntax meaning to redirect what would go to
filehandle 2 (STDERR) to filehandle 1 (STDOUT). In other words,
FILEHANDLE will return data from both output streams. This trick is
covered in perlfaq8.
This use of the vertical bar ('|') character is a pipe open, covered
in perlopentut.
The dot ('.') is the string concatenation operator; see perlop.
Does that give you what you need? Hope this helps!
