The shell redirection command used for creating file in another di

Question

I need to create a log report say .txt file in one directory that saves all the errors that raise after execution of a program which resides in another directory, so which shell command is used in linux.

Answer 1

./command > ./outfiles/out.file 2> ./errfiles/err.file should do the trick for you.

Sort of answered at: How to pipe stderr, and not stdout? but that questioner wanted a pipe.
