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?
