cat is not in /usr/bin for macOS. I completed the task switching to my raspberry pi.

remote: [tester::#MG5] Running ./your\_program.sh  
remote: [your-program] $ type cat  
remote: [your-program] cat is /bin/cat  
remote: [tester::#MG5] ^ Line does not match expected value.  
remote: [tester::#MG5] Expected: “cat is /usr/bin/cat”  
remote: [tester::#MG5] Received: “cat is /bin/cat”  
remote: [your-program] $  
remote: [tester::#MG5] Assertion failed.  
remote: [tester::#MG5] Test failed
