NAME
       spell, hashmake, spellin, hashcheck - find spelling errors

SYNOPSIS
       spell [ -v ] [ -b ] [ -x ] [ -l ] [ -i ] [ +local_file ] [ files ]

       /usr/lib/spell/hashmake

       /usr/lib/spell/spellin n

       /usr/lib/spell/hashcheck spelling_list

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.

       Copies of all output from spell are accumulated in the default
       history file.  You can specify an alternate history file by setting
       the history file name argument.  For the name of the history file
       argument and the default setting (see "FILES").

       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 > spellout1
       $ 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 misspelled 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 misspelled
       words are listed as well as all of the words not literally in the
       spelling list.  The plausible derivations of these words are shown.

FILES
       H_SPELL=/var/adm/spellhist  History file.

SEE ALSO

       eqn(1), tbl(1).

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.
