Redirection Well Done! 35 out of 38 passed

We passed 35 out of 38 tests.
All failed ones are about background process.
I use
[./solution < cmd > 1]
[./3600sh < cmd > 2]
then
[diff 1 2]

It turns out that all outputs are identical.

Not really sure why it fails.
Might because we didn’t handle background process well.
There are people complaining about the same issues on Piazza
