📋
Quick Overview: rfswift last is your first stop for seeing what containers exist. It shows all containers (running and stopped) with their essential information at a glance.
No Filtering Options: Unlike docker ps, the last command shows all containers without filtering options. Use grep, awk, or pipe to docker ps for advanced filtering.
All Containers Shown: rfswift last shows both running AND stopped containers (equivalent to docker ps -a). Use grep "Up" to see only running ones, or grep "Exited" for stopped ones.
