dpkg
とapt-get
は、ソフトウェアをインストールする2つの異なる方法です。基本的に、apt-get、aptitude、およびsynapticは、debianのdpkgパッケージ管理プログラムの上に構築されています。それらはすべて同じ基本機能を実行します-パッケージ管理ですが、いくつかの追加機能があります。apt-getの追加機能の1つは、依存関係をインストールしますが、dpkgはインストールしないことです。
-p / purgeについて...
手段とはsetttingsと構成ファイルを含む、すべてのものを削除します。マニュアルから:-P
dpkg
--purge
-r, --remove, -P, --purge package...|-a|--pending
Remove an installed package. -r or --remove remove everything
except conffiles. This may avoid having to reconfigure the pack‐
age if it is reinstalled later. (Conffiles are configuration
files that are listed in the DEBIAN/conffiles control file). -P
or --purge removes everything, including conffiles. If -a or
--pending is given instead of a package name, then all packages
unpacked, but marked to be removed or purged in file
/var/lib/dpkg/status, are removed or purged, respectively. Note:
some configuration files might be unknown to dpkg because they
are created and handled separately through the configuration
scripts. In that case, dpkg won't remove them by itself, but the
package's postrm script (which is called by dpkg), has to take
care of their removal during purge. Of course, this only applies
to files in system directories, not configuration files written
to individual users' home directories.
Removing of a package consists of the following steps:
1. Run prerm script
2. Remove the installed files
3. Run postrm script
同じことがのために行くpurge
の中でapt-get
。
remove
remove is identical to install except that packages are removed
instead of installed. Note the removing a package leaves its
configuration files in system. If a plus sign is appended to the
package name (with no intervening space), the identified package
will be installed instead of removed.
purge
purge is identical to remove except that packages are removed and
purged (any configuration files are deleted too).
基本的には同じオプションです。ご注意ください:依存関係の削除はdpkgでは起こりません。apt-getは依存関係を削除します
