Background info from MSKB While the accepted answer to this question is correct, it really doesn't do much to explain why it works, and since the syntax is not immediately clear I did a quick google to find out what was actually going on.

The exec built-in has the power to rewire the stream for the whole shell session, so to speak, whether interactively or via script. Something like. Yet another way is via functions.

As kopciuszek noted in his answer, we can write function declaration with already attached redirection, that is.

Commands such as time and strace write their output to stderr by default. In case of time command, the only viable alternative is to redirect output of whole command , that is. Other commands, such as strace or dialog provide means to redirect stderr. There is also an option for writing a textfile for each subprocess that strace sees. There's also the method of named pipes. I recommend reading the linked post about the dialog command for thorough description of what's happening.

Well, what if there are some warnings you want to inform the user about during the CSV generation process. For example, the user is calling a deprecated method, or they didn't provide enough values for a row, so you fill them in with empty values. It does not wait for the first application to completely finish before the next application runs.
