How to use aspell on the command line

I need to use aspell or any other spe开发者_Python百科ll checking in a command line program. I need to check for a single word only not on a file....

echo $WORD | aspell -a

If you simply require a list of misspelled words then

echo 'word lister to check' | aspell --list

will return the incorrectly spelled words or nothing at all if there are no misspellings

from command line

To check for single word

echo 'blog' | /path_to_aspell/aspell -a

To check for a sentence/paragraph

echo 'blog ia a goud one' | /path_to_aspell/aspell -a

If you have american-english (5) or british-english (5) installed on your linux system, you can simply something similar to the following:

# *note: dog is misspelled below
str=doog                                 
egrep -i ^${str}$ /usr/share/dict/words
if[ $? -ne 0 ] ; then
    echo "$str misspelled?"
fi
