Why would they add "(which already exists)"? It just confuses matters. In other questions they do not add this qualification. Makes me wonder if that file is empty? Maybe first # cat /opt/KUTR00401/KUTR00401.txt to make sure it's empty. If it's not, # echo "name-of-top-cpu-pod" >> /opt/KUTR00401/KUTR00401.txt Instead of # echo "name-of-top-cpu-pod" > /opt/KUTR00401/KUTR00401.txt Or am I overthinking here?

Frankly speaking, why bother typing the pod name with this single liner: # Dry-run k top po -l name=overloaded-cpu --sort-by=cpu -A --no-headers | head -n 1 | awk '{print $2}' # Exec k top po -l name=overloaded-cpu --sort-by=cpu -A --no-headers | head -n 1 | awk '{print $2}' >> /opt/KUTR00401/KURT00401.txt
