DESCRIPTION
Spell collects words from the named files and looks them up in a
spelling list. Words not in the list or words not 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.
Spell 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 standardise.
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 -i
option, spell will ignore all chains of 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. Although it is more
haphazard than an ordinary dictionary, spell is also more
effective with respect to proper names and popular technical
words. Coverage of the specialized vocabularies of biology,
medicine, and chemistry is light.
You can specify pertinent auxiliary files by name arguments,
indicated below with their default settings (see "FILES").
Copies of all output are accumulated in the history file. The
stop list filters out misspellings (e.g., thier=thy-y+ier) that
would otherwise pass.
Three routines help maintain and check spell's hash lists:
hashmake Reads a list of words from the standard input and
writes the corresponding nine-digit hash code on the
standard output.
spellin n Reads n hash codes from the standard input and
writes a compressed spelling list on the standard
output. Information about the hash coding is
printed on standard error.
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.

EXAMPLES
$ cat spellcheck
This is a sample file taht can be used to test teh spell comand.
Obviously there are some speling errers.
$ spell spellcheck > spellout
$ cat spellout1
comand
errers
speling
taht
teh
$
This example shows the contents of a file with some spelling
errors. The spell command is used to check the file for errors,

and the output is sent to a file called spellout1. As you can
see, all of the mispelled words are in this file.
$ spell -v spellcheck >spellout2
$ cat spellout2
comand
errers
speling
taht
teh
+ly Obviously
+d used
$
This example uses the -v option. With this option, the mispelled
words are listed as well as all of the words not literally in the
spelling list. The plausible derivations of these words are
shown.

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.
