`sh` is required for running the containers now

[mosajjal]

Hi,

in run_in_file_program.sh, use of sh command is required. I've built my container FROM scratch so it won't run with this.

Is sh a requirement for running the challenges? if so, we should make sure it's reflected in the docs.

Cheers,

Interestingly, I seem to be the only person having this problem lol

Hi @mosajjal,

I tweeted about it yesterday:

Sorry for the short notice, wanted to apply the changes ASAP.
Right, it's needed to be added to the prime challenge doc as well.
