- Standard output, FD 1, for writing, defaults to writing to the screen.
- Standard error, FD 2, for writing errors and warnings, defaults to writing to the screen.

Variables can be explicitly set to be exported with the `-x` or `--export` switch, or not exported with the `-u` or `--unexport` switch. The exporting rules when creating or updating a variable are identical to the scoping rules for variables:
-# If a variable is explicitly set to either be exported or not exported, that setting will be honored.
-# If a variable is not explicitly set to be exported or not exported, but has been previously defined, the previous exporting rule for the variable is kept.
