Linux Fundamentals - Filter Contents

Hello,

i am very new to Linux and working my way trough the academy. in this section i learned about different ways to influence the output

the practice was challenging but interesting. but the question seem to have nothing to do with what i’ve learned so far. so i am unable to answer the questions because i dont even know where to start and dont know the commands like “curl”. so i dont want to “cheat” with google or ai and im wondering if these questions belong to this topic and if i should be able to solve it with the knowledge i’ve gathered so far.

king regards
