Correct, file handle 1 for the process is STDOUT, redirected by the 1>
or by >
(1 can be omitted, by convention, the command interpreter [cmd.exe] knows to handle that).
File handle 2 is STDERR, redirected by 2>
.
Note that if you're using these to make log files, then unless you're sending the outut to _uniquely_named_ (eg date-and-time-stamped) log files, then if you run the same process twice, the redirected will overwrite (replace) the previous log file.
The >>
(for either STDOUT or STDERR) will APPEND not REPLACE the file. So you get a cumulative logfile, showwing the results from all runs of the process - typically more useful.
Happy trails...
