1. The standard output of the redirect command to a file.
2. Standard output and error output redirect to a file.
3. Send the standard output of the program to the standard input of program2, for processing.
4. Send standard output and error output to program2 input for processing.

Answer 2

Usually, to process the output of commands in a batch file, they drive the command into a loop of the form:

for /f "tokens=xxx delims=yyy" %%a in ('тут нужная команда') do (
   echo %%a
)

and inside the loop access the output of the command line by line.
You can split output lines into tokens, set token separators, skip lines at the beginning using the loop parameters (specified in quotes).
