NAME
ispell - Correct spelling for a file
SYNOPSIS
ispell [ file | -a | -l ]
DESCRIPTION
Ispell is fashioned after the spell program from ITS (called
ispell on Twenex systems.) The most common usage is "ispell
filename". In this case, ispell will display each word
which does not appear in the dictionary, and allow you to
change it. If there are "near misses" in the dictionary
(words which differ by only a single letter, a missing or
extra letter, or a pair of transposed letters), then they
are also displayed. If you think the word is correct as it
stands, you can type either "Space" to accept it this one
time, or "I" to accept it and put it in your private dic-
tionary. If one of the near misses is the word you want,
type the corresponding number. Finally, if none of these
choices is right, you can type "R" and you will be prompted
for a replacement word.
When a misspelled word is found, it is printed at the top of
the screen. Any near misses will be printed on the follow-
ing lines, and finally, two lines containing the word are
printed at the bottom of the screen. If your terminal can
type in reverse video, the word itself is highlighted.
The -l or "list" option to ispell is used to produce a list
of misspelled words from the standard input.
The -a is intended to be used from other programs through a
pipe. In this mode, ispell expects the standard input to
consist of single words. Each word is read, and a single
line is written to the standard output. If the word was
found in the main dictionary, or your personal dictionary,
then the line contains only a '*'. If the word was found
through suffix removal, then the line contains a '+', a
space, and the root word. If the word is not in the dic-
tionary, but there are near misses, then the line contains
an '&', a space, and a list of the near misses separated by
spaces. Also, each near miss is capitalized the same as the
input words. Finally, if the word neither appears in the
dictionary, and there are no near misses, then the line con-
tains only a '#'. This mode is also suitable for interac-
tive use when you want to figure out the spelling of a sin-
gle word. (These characters are the same as the codes that
the real spell program uses.)

BUGS
It takes about five seconds for ispell to read in the hash
table.
Perhaps more than ten choices should be allowed for near
misses.
The hash table is stored as a quarter-megabyte array, so a
PDP-11 version does not seem likely.
Ispell should understand more troff syntax, and deal more
intelligently with contractions.
