SPELL(1) INTERACTIVE UNIX System SPELL(1)
NAME
spell, hashmake, spellin, hashcheck - find spelling errors
SYNOPSIS
spell [ -v ] [ -b ] [ -x ] [ -l ] [ +local_file ] [ files ]
/usr/lib/spell/hashmake
/usr/lib/spell/spellin n
/usr/lib/spell/hashcheck spelling_list
DESCRIPTION
The spell command collects words from the named files and
looks them up in a spelling list. Words that neither occur
among nor are derivable (by applying certain inflections,
prefixes, and/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.
The spell command ignores most troff(1), tbl(1), and eqn(1)
constructions.
Under the -v option, all words not literally in the spelling
list are printed, and plausible derivations from the words
in the spelling list are indicated.
Under the -b option, British spelling is checked. Besides
preferring centre, colour, programme, speciality, travelled,
etc., this option insists upon -ise in words like standar-
dise.
Under the -x option, every plausible stem is printed with =
for each word.
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. Under the
-l option, spell will follow the chains of all included
files.
Under the +local_file option, 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 spelling list is based on many sources, and while more
haphazard than an ordinary dictionary, is also more effec-
tive with respect to proper names and popular technical
words. Coverage of the specialized vocabularies of biology,
medicine, and chemistry is light.

Pertinent auxiliary files may be specified by name argu-
ments, indicated below with their default settings (see
FILES ). Copies of all output are accumulated in the his-
tory file. The stop list filters out misspellings (e.g.,
thier=thy-y+ier) that would otherwise pass.
Three routines 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 output.
spellin Reads n hash codes from the standard input and
writes a compressed spelling list on the stan-
dard 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 out-
put.

BUGS
The spelling list's coverage is uneven; new installations
will probably wish to monitor the output for several months
to gather local additions; typically, these are kept in a
separate local file that is added to the hashed
spelling_list via spellin.
