spellin [ list ]
spellout [ -d ] list
Spell collects words from the named documents, and looks them up in a spelling list.
Words that neither occur among nor are derivable (by applying certain inflections, pre-
fixes or suffixes) from words in the spelling list are printed on the standard output. If
no files are named, words are collected from the standard input.
Spell ignores most troff, tbl and eqn(1) constructions.
Under the -v option, all words not literally in the spelling list are printed, and plausi-
ble derivations from spelling list words are indicated.
Under the -b option, British spelling is checked. Besides preferring centre, colour, spe-
ciality, travelled, etc., this option insists upon -ise in words like standardise, Fowler
and the OED to the contrary notwithstanding.
Under the -x option, every plausible stem is printed with `=' for each word.
The spelling list is based on many sources. While it is more haphazard than an ordinary
dictionary, it is also more effective with proper names and popular technical words. Cov-
erage of the specialized vocabularies of biology, medicine and chemistry is light.
The auxiliary files used for the spelling list, stop list, and history file may be speci-
fied by arguments following the -d, -s, and -h options. The default files are indicated
below. Copies of all output may be accumulated in the history file. The stop list fil-
ters out misspellings (e.g. thier=thy-y+ier) that would otherwise pass.
Two routines help maintain the hash lists used by spell. Both expect a set of words, one
per line, from the standard input. Spellin combines the words from the standard input and
the preexisting list file and places a new list on the standard output. If no list file
is specified, the new list is created from scratch. Spellout looks up each word from the
standard input and prints on the standard output those that are missing from (or present
on, with option -d) the hashed list file. For example, to verify that hookey is not on
the default spelling list, add it to your own private list, and then use it with spell,
echo hookey | spellout /usr/dict/hlista
echo hookey | spellin /usr/dict/hlista > myhlist
spell -d myhlist huckfinn
/usr/dict/hlist[ab] hashed spelling lists, American & British, default for -d
/usr/dict/hstop hashed stop list, default for -s
/dev/null history file, default for -h
/tmp/spell.$$* temporary files
deroff(1), sort(1), tee(1), sed(1)
The spelling list's coverage is uneven; new installations will probably wish to monitor
the output for several months to gather local additions.
British spelling was done by an American.
