#2

to sort the lakes.txt information and redirected into sorted-lakes, the lesson wrote:
$ cat lakes.txt | sort > sorted-lakes.txt

but could I write $ sort lakes.txt > sorted-lakes.txt?
the result seems like the same, but is it right to write this way?

cat desserts.txt | sort | uniq > uniq-desserts.txt
cat desserts.txt | uniq | sort > uniq-desserts.txt
