- word expansion errors are considered non-fatal errors that cause the
current command to fail, even in Posix mode
- when executing a shell function, the loop state (while/until/etc.) is
not reset, so `break' or `continue' in a shell function will break or
continue loops in the calling context. Bash-4.4 and later reset the
loop state to prevent this.

ily the file that appears first in PPAATTHH. If the --aa option is
used, ttyyppee prints all of the places that contain an executable
ily the file that appears first in PPAATTHH. If the --aa option is
used, ttyyppee prints all of the places that contain an executable
named _n_a_m_e. This includes aliases and functions, if and only if
the --pp option is not also used. The table of hashed commands is
not consulted when using --aa. The --ff option suppresses shell
