Name
       spell, spellin, spellout - check text for spelling errors

Syntax
       spell [-v] [-b] [-x] [-d hlist] [+local-file] [-s hstop] [-h spellhist] [file...]

       spellin [list]

       spellout [-d] list

Description
       The command collects words from the named documents, and looks them up in a spelling list.  Words that are not on the spelling list and are
       not derivable from words on the list (by applying certain inflections, prefixes or suffixes) are printed on the	standard  output.   If	no
       files are specified, words are collected from the standard input.

       The command ignores most and constructions.

       Two  routines help maintain the hash lists used by Both expect a set of words, one per line, from the standard input.  The command combines
       the words from the standard input and the preexisting list file and places a new list on the standard output.  If no list  file	is  speci-
       fied,  a  new  list  is generated.  The command looks up each word from the standard input and prints on the standard output those that are
       missing from (or present on, with option -d) the hashed list file.  For example, to verify that hookey is not on the default spelling list,
       add it to your own private list, and then use it with
       echo  hookey  |	spellout  /usr/dict/hlista
       echo  hookey  |	spellin  /usr/dict/hlista  >  myhlist
       spell  -d  myhlist <filename>

Options
       -v	      Displays words not found in spelling list with all plausible derivations from spelling list.

       -b	      Checks  data  according  to British spelling.  Besides preferring centre, colour, speciality, travelled, this option insists
		      upon -ise instead of -ize in words like standardise.

       -x	      Precedes each word with an equal sign (=) and displays all plausible derivations.

       -d hlist       Specifies the file used for the spelling list.

       -h spellhist   Specifies the file used as the history file.

       -s hstop       Specifies the file used for the stop list.

       +local-file    Removes words found in local-file from the output of the command.  The argument local-file is the name of a file provided by
		      the  user  that contains a sorted list of words, one per line.  With this option, the user can specify a list of words for a
		      particular job that are spelled correctly.

       The auxiliary files used for the spelling list, stop list, and history file may be specified by arguments following  the  -d,  -s,  and	-h
       options.   The  default files are indicated below.  Copies of all output may be accumulated in the history file.  The stop list filters out
       misspellings (for example, thier=thy-y+ier) that would otherwise pass.

Restrictions
       The coverage of the spelling list is uneven; new installations will probably wish to monitor the output for several months to gather  local
       additions.

       The command works only with ASCII text files.

Files
       /usr/dict/hlist[ab] hashed spelling lists, American &			 British, default for -d
       /usr/dict/hstop	   hashed stop list, default for -s
       /dev/null	   history file, default for -h
       /tmp/spell.$$*	   temporary files
       /usr/lib/spell
