I have a bat file that has a large text output when it runs a program. If I run that program directly, I can redirect the output to a file with '>' or pipe it to MORE. However, I can't redirect or pipe the output when executing the bat file.

file.bat > a.log
file.bat | more

Neither of these work. Is it possible to make this work as expected?

Hi there! You can try using COPY CON to redirect the i/o of the DOS command line (CONsole).
Another idea is using CTTY command. It can be used to run a DOS PC via serial terminal.
Maybe it works with a file instead, as well, not sure. COM, AUX, PRN, CON etc. are special files, essentially.

DOS: command /c file.bat > a.log
