Show Linux memory and swap usage
free -hThe output matches the expected target and exits without an error.
Show the ten processes using the most memory
ps aux | sort -nrk 4,4 | head -10The output matches the expected target and exits without an error.
Inspect Linux CPU, memory, and I/O pressure stall metrics
grep -H . /proc/pressure/{cpu,memory,io}The output matches the expected target and exits without an error.
