sed -E -e "s/$(aspell list <file | sort -u | paste -s -d'|')//g" file > newfile

This uses command substitution $(...) to insert the output of aspell list <$file into a sed search and replace operation.

aspell's output is also unique sorted and paste is used to join each line with | to make a valid extended regular expression.

You can test it with, e.g., diff -u file newfile

AFAIK, aspell doesn't have an auto-correct mode. This is probably a Good Thing.

sed -E -e "s/$(aspell list <file | sort -u | paste -s -d'|' |
               sed -e 's/^/\\b(/; s/$/)\\b/' )//g" \
    file > newfile

This uses command substitution $(...) to insert the output of aspell list <$file into a sed search and replace operation.

aspell's output is also unique sorted and paste is used to join each line with |. Finally it is piped through sed to add \b word-boundary anchors as well as open and close parentheses. All of which constructs a valid extended regular expression like \b(word1|word2|word3|...)\b to use as the search regexp in the sed search and replace command.

You can test the result of the entire command with, e.g., diff -u file newfile

grep -v -F -f <(aspell list "$file") "$file" > "$file.new"

This uses processs substitution <(...) to supply the output of aspell list "$file" as an input file to grep's -f (aka --file) option.

Otherwise, it's just standard use of grep -v -F (print only non-matching lines, use fixed strings rather than regexps).

Use -i if you want the search to be case-insensitive, which will be considerably slower.
