SPELL(1) General Commands Manual SPELL(1)
spell, hashmake, spellin, hashcheck - report spelling errors
spell [ -blvx ] [ -d hlist ] [ -h spellhist ] [ -s hstop ] [
+local_file ] [ filename ] ...
spell collects words from the named files, and looks them up in a
hashed spelling list. Words that do not appear in the list, or cannot
be derived from those that do appear by applying certain inflections,
prefixes or suffixes, are displayed on the standard output.
If there are no filename arguments, words to check are collected from
the standard input. spell ignores most troff(1), tbl(1), and eqn(1)
constructs. Copies of all output words are accumulated in the history
file, and a stop list filters out misspellings (for example,
their=thy-y+ier) that would otherwise pass.
By default, spell (like deroff(1)) follows chains of included files
(.so and .nx troff(1) requests), unless the names of such included
files begin with /usr/lib.
If a +local_file argument is specified, words found in local_file are
removed from spell's output. local_file is the name of a user-provided
file that contains a sorted list of words, one per line. With this
option, the user can specify a set of words that are correct spellings
(in addition to spell's own spelling list) for each job.
The standard spelling list is based on many sources, and while more
haphazard than an ordinary dictionary, is also more effective in
respect to proper names and popular technical words. Coverage of the
specialized vocabularies of biology, medicine and chemistry is light.
Three programs help maintain and check the hash lists used by spell:
hashmake Reads a list of words from the standard input and writes
the corresponding nine-digit hash code on the standard out-
spellin Reads n hash codes from the standard input and writes a
compressed spelling list on the standard output.
hashcheck Reads a compressed spelling_list and recreates the nine-
digit hash codes for all the words in it; it writes these
codes on the standard output.
-b Check British spelling. Besides preferring "centre",
"colour", "programme", "speciality", "travelled", and so
on, this option insists upon -ise in words like standard-
ize, despite what Fowler and the OED say.
-l Follow the chains of all included files.
-v Print all words not literally in the spelling list, as well
as plausible derivations from spelling list words.
-x Print every plausible stem with `=' for each word.
-d hlist Use the file hlist as the hashed spelling list.
Place misspelled words with a user/date stamp in file
-s hstop Use hstop as the hashed stop list.

The spelling list's coverage is uneven; new installations may wish to
monitor the output for several months to gather local additions.
British spelling was done by an American.
Misspelled words can be monitored by default by setting the H_SPELL
variable in /usr/bin/spell to the name of a file that has permission
spell works only on English words defined in the US ASCII codeset.
