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?
What is the differences between:
sort desserts.txt | uniq > uniq-desserts.txt
cat desserts.txt | sort | uniq > uniq-desserts.txt
cat desserts.txt | uniq | sort > uniq-desserts.txt
The last one doesnt out put the result with uniq effect. why?

interested in the answer to this question as well!
i had the same question! is there a difference between the two lines?
I had this same question. Seems like extra steps.
Uniq only removes adjacent duplicates separated by new lines, therefore the text file contents must be sorted before uniq will accurately remove all duplicates.
Try $ uniq deserts.txt
It removes “Sahara Desert”, which is one line below “Sahara Desert,” but not Kalahari Desert.
