* Typo fix. * Style change: always use $(), never ``. The Lynis code already mostly used $(), but backticks were sprinkled around. Converted all of them. * Lots of minor spelling/typo fixes. FWIW these were found with: find . -type f -print0 | xargs -0 cat | aspell list | sort -u | egrep '^[a-z]+$' | less And then reviewing the list to pick out things that looked like misspelled words as opposed to variables, etc., and then manual inspection of context to determine the intention.
