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 SPELL(1) SPELL(1) and prints on the standard output those that are missing from (or present on, with option -d) the hash list.

British spelling was done by an American.
