Do you want to run a spell check on your blog or web site? Perhaps not every day - but occasionally this can be helpful to remove basic errors. You can combine a wget download with a find command and aspell to get a list of your typos. Here's how:
#!/bin/sh
#check spelling on The Molecular Universe
wget --mirror -p --html-extension --convert-links \
-P ./ http://www.themolecularuniverse.com
find www.themolecularuniverse.com -name "*.html" |
while read file
do
echo $file
aspell --mode=html list < $file | sort -u
done
Put the commands above into a file, then execute the file at the command line, and you will run a spell check of www.themolecularuniverse.com - add an argument and/or some error checking to check your own sites.
