Rpm, used for the management suite, was originally a Red Hat Linux distribution program designed to manage Linux suites. It is popular because it follows GPL rules and is powerful and convenient.

Rpm-a

Rpm-Q interpretation: query whether a package is installed

Rpm-qa

Rpm-qa-Q query all suites using query mode (query)-a (all) interpretation: list all installed rpm package

The difference with rpm-an is that it has been, for example:

Rpm-qa | grep

Rpm-qa | grep xxx | Pipeline technology. Delete means grep search-A text search tool: search for xxx in the information returned by-qa and return it as the final result

Rpm-qa | grep-I xxx-I is not case-sensitive to xxx. Of course, as a search tool, grep can also be combined with other commands

Rpm-e-requires careful "uninstall"

Normally, when uninstalling, we use the

Rpm-e xxx but if the software yyy is "dependent" on xxx-that is, yyy must have xxx to run

Will return

Error: xxx is needed by yyy can forcibly delete ↓ at this time without checking for dependencies (with caution)
