apt-cache is a command that queries APT's package cache on Debian-based Linux. search finds packages by name or description, show displays detailed information such as version and dependencies, and policy shows the installation candidate version and repository priorities. It is a read-only command that does not change the system, and the newer apt command has integrated some of these functions as apt search and apt show.
