There are several commands that you can use to display package description, information, version, and usage in Linux. Here are a few options:

To use this command, type apt-cache show package-name, where package-name is the name of the package you want to display information about. For example:apt-cache show firefox
This will display detailed information about the firefox package, including its description, version, dependencies, and other metadata.
yum info: This command is used to display information about a package in the Yellowdog Updater, Modified (YUM) package manager, which is used in Red Hat and CentOS systems. To use this command, type yum info package-name, where package-name is the name of the package you want to display information about. For example:yum info firefox
This will display detailed information about the firefox package, including its description, version, dependencies, and other metadata.
rpm -qi: This command is used to display information about an RPM package. To use this command, type rpm -qi package-name, where package-name is the name of the package you want to display information about. For example:rpm -qi firefox
