Advanced Packaging Tool (APT)'s origins start in Debian - a distro from where
many other distros started from. APT is simply set of APIs. The command
line tools apt and apt-get interact with APT. In summary,
- apt: The more user friendlier version of the tools.
- apt-get: The older of the two, backwards compatible and OG developer focused.
(there are others: apt-cache, ...)
Conclusion: Stick with apt if you can. Use apt-get if you need specific function
alities that are otherwise unavialable. Doesnt matter much anyways none are dep
recated!
