Why not just do the following:
sort -c filename
If sort returns nothing, the words are sorted. If the words are not sorted,
sort will return something along the lines of:
sort: filename:15: disorder: abbs
You can also do the following if you just want to know if the words are
sorted.
sort -c filename 2>/dev/null && echo Already Sorted || echo Not Sorted
I don't know the specifics of why grep is being used or the problem, but
damn that is overkill just to find out if a list of words are sorted.
'man sort' will give you are the details for using sort.
