Sometimes I just forget how things work.
Assuming that myfile in both situations has something inside of it.
cat <myfile >myfile
(shows an empty file)
wc <myfile >myfile
0 0 0
How does it work does the shell first read ">myfile" and empty it out, or
does the shell read "<myfile" first, give a word count to wc and then empty
it out with >myfile, producing the output 0 0 0
