SPELL(1)                                                 SPELL(1)

     NAME
          spell, spellin, spellout - find spelling errors

     SYNOPSIS
          spell [ option ] ...  [ file ] ...

          /usr/src/cmd/spell/spellin [ list ]

          /usr/src/cmd/spell/spellout [ -d ] list

     DESCRIPTION
          Spell collects words from the named documents, and looks
          them up in a spelling list.  Words that neither occur among
          nor are derivable (by applying certain inflections, prefixes
          or suffixes) from words in the spelling list are printed on
          the standard output.  If no files are named, words are col-
          lected from the standard input.

          Spell ignores most troff, tbl and eqn(1) constructions.

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

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

          Under the -x option, every plausible stem is printed with
          `=' for each word.

          The spelling list is based on many sources, and while more
          haphazard than an ordinary dictionary, is also more effec-
          tive in respect to proper names and popular technical words.
          Coverage of the specialized vocabularies of biology, medi-
          cine and chemistry is light.

          Pertinent auxiliary files may be specified by name argu-
          ments, indicated below with their default settings.  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.

          Two routines help maintain the hash lists used by spell.
          Both expect a list of words, one per line, from the standard
          input.  Spellin adds the words on the standard input to the
          preexisting list and places a new list on the standard out-
          put.  If no list is specified, the new list is created from
          scratch.  Spellout looks up each word in the standard input

          and prints on the standard output those that are missing
          from (or present on, with option -d) the hash list.

     FILES

          British

     BUGS
          The spelling list's coverage is uneven; new installations
          will probably wish to monitor the output for several months
          to gather local additions.
          British spelling was done by an American.
