aspell check [options] filename
aspell is a utility that can function as an ispell -a replacement, as an independent spell checker, as a test utility to test out Aspell features, and as a utility for managing dictionaries.
|-mode=mode||The mode to use when checking files. The available modes are none, url, email, sgml, tex, texinfo, nroff and any others available on your system.|

|-encoding=name||Encoding the document is expected to be in. The default depends on the current locale.|
|-master=name||The main dictionary to use.|
