Why does it not work?. "sort filename.txt > filename.txt"


Hi. I wonder that when I type:

& sort filename.txt > filename.txt
It doesn't work. It only ends up becoming a empty file.
I also tried using "wc" command.It also doesn't work.
anyone can explain for me.
Thanks so much.


and what happens if you do ....

ls > filename.txt
cat filename.txt
sort filename.txt > filename.txt
