George,
2>&1 takes stderr stream and pushes it to stdout. translation:
that way *all* the output from a command, both regular and error messages
shows up at the same spot, ready to be diverted somewhere else. this
harkens back to the beginning of c, where 3 files were defined for *every*
program: 1 - stdout, 2 - stderr and 3 - stdin. guess what they are :-)
