16.3. How Do I Spell That Word?
Are you writing a document and want to check the spelling of a word
before you finish (if you aren't using a word
processor with automatic spelling correction, that is)? A Unix system
gives you several ways to do this.
NOTE:
Because this is Unix, you can use any of these approaches when you
write a script of your own.
-
If you aren't sure
which of two possible spellings is right, you can use the
spell command with no arguments to find out. Type
the name of the command, followed by a RETURN, then type the
alternative spellings you are considering. Press CTRL-d (on a line by
itself) to end the list. The spell command will
echo back the word(s) in the list that it considers to be in error:
$ spell
misspelling
mispelling
CTRL-d
mispelling
-
If you're using ispell ( Section 16.2) or the newer aspell, you
need to add the -a option. The purpose of this
option is to let the speller interact with other programs; there are
details in the programs' documentation. But, like
most Unix filters, you can also let these programs read a word from
standard input and write their response on standard output; it will
either tell you that the spelling is right or give you a list of
suggestions. aspell and ispell
will use their local dictionaries and improved spelling rules.
As an example, let's check the spelling of
outragous and whut with
both ispell and aspell:
$ ispell -a
@(#) International Ispell Version 3.1.20 10/10/95
outragous whut
& outragous 1 0: outrageous
& whut 5 10: hut, shut, what, whet, whit
CTRL-d
$ aspell -a
@(#) International Ispell Version 3.1.20 (but really Aspell .32.6 alpha)
outragous whut
& outragous 3 0: outrageous, outrages, outrage's
& whut 5 10: what, whet, whit, hut, shut
CTRL-d
$
When these spellers start, they print a version message and wait for
input. I type the words I want to check and press RETURN. The speller
returns one result line for each word:
-
A result of * means the word is spelled correctly.
-
A line starting with & means the speller has
suggestions. Then it repeats the word, the number of suggestions it
has for that word, the character position that the word had on the
input line, and finally the suggestions.
-
So ispell suggested that
outragous might be
outrageous. aspell also came
up with outrages and
outrage's.
(I'd say that
outrage's is barely a word. Be
careful with aspell's
suggestions.) Both spellers had five suggestions for
whut; the differences are interesting . . .
-
A result of # means there were no suggestions.
After processing a line, the spellers both print an empty line. Press
CTRL-d to end input.
-
Another way to do the same thing is
with look (Section 13.14). With just one argument,
look searches the system word file,
/usr/dict/words, for words starting with the
characters in that one argument. That's a good way
to check spelling or find a related word:
% look help
help
helpful
helpmate
look
uses its -df options automatically when it searches
the word list. -d ignores any character that
isn't a letter, number, space or tab;
-f treats upper- and lowercase letters the same.
