spell
The spell command filters through a file looking
for things that look like words, and spits out those which don't
appear in the computers dictionary file.
Examples:
- spell myfile displays all the possible
misspellings from the file `myfile'
- spell myfile > errors writes all the
possible misspellings from the file `myfile' to a file
named `errors'
look
The look command displays all the words in the
computer's built-in dictionary which begin with the given letters.
Examples:
- look aque prints out `aqueduct' and `aqueous'
- look persi prints out `Persia', `Persian',
`persiflage', `persimmon', `persist', `persistent'
Together, these commands eliminate the need to burden text editors
with a built-in spellchecker. You can find which words are misspelled
by using spell, and you can find proper spellings
using look.
