Question about 2022 solution (all 3)

1:54pm Mon 3rd Jun, ANONYMOUS

Hi Sir, Good afternoon. I have a doubt about year 2022 paper solution. Why we use exit 0 after stderr, instead of exit 1? Thanks

Hi, Fair question. That is just a matter of personal taste on my part. Not important. Recalled that exit status 0 implies success; status > 1 implies an error. I assume that if the user types a command without options they are trying to find out what the options are. Many programs achieve this with a -h or --help option. The response with the options is therefore a successful use of the program, not the result of an error state, hence status 0 in this case. Small stylistic point only. Cheers MichaelW 👨‍🎨
