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
     spell 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.

     spell ignores most troff(1), tbl(1), and eqn(1) construc-
     tions.

     -v        All words not literally in the spelling list are
               printed, and plausible derivations from the words
               in the spelling list are indicated.

     -b        British spelling is checked.  Besides preferring
               centre, colour, programme, speciality, travelled,
               etc., this option insists upon -ise in words like
               standardise, Fowler and the OED (Oxford English
               Dictionary) to the contrary notwithstanding.

     -x        Every plausible stem is displayed, one per line,
               with = preceding each word.

     -l        Follow the chains of all included files.  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.

     +local_file
               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.  The list must be sorted with the ordering
               used by sort(1) (e.g. upper case preceding lower
               case).  If this ordering is not followed, some
               entries in local_file may be ignored.  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.

     Alternate auxiliary files (spelling lists, stop list, his-
     tory file) may be specified on the command line by using
     environment variables.  These variables and their default
     settings are shown in the FILES section.  Copies of all out-
     put 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 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.  This is the first
                 step in creating a new spelling list or adding
                 words to an existing list; it must be used prior
                 to using spellin.

     spellin     Reads n hash codes (created by hashmake) from
                 the standard input and writes a compressed spel-
                 ling list on the standard output.  Use spellin
                 to add words to an existing spelling list or
                 create a new spelling list.

     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.  It takes as input an existing spelling
                 list (hlista or hlistb) or a list created or
                 modified by spellin.  By using hashcheck on an
                 existing compressed spelling_list and hashmake
                 on a file of selected words, you can compare the
                 two output files to determine if the selected
                 words are present in the existing spelling_list.

NOTES
     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.
