0,1,2 are the file descriptor for STDIN, STDOUT and STDERR respectively.

0 -- STDIN - standard input , is by default keyboard.
1 -- STDOUT - standard output, is by default terminal
2 -- STDERR - standard error, is by default terminal

In your command, STDOUT is set to a file ( with redirection, 1 is optional here ) and STDERR is set to STDOUT ( wherever the STDOUT is set)

"&" is the syntax for that. So 2>&1 means standard error is being redirected to standard output which is finally set to a file. so both stdout and stderr will go to file.

just to make sure, its not $1
