《RPM多種用法（舉例）及在CentOS中幹掉console-kit-daemon》
2013-07-07 `
今天優化系統的時候，發現有個佔用系統資源比較多的 console-kit-daemon 進程/線程
爲了在CentOSv6.2系統當中消滅它(原來那玩意兒用於用戶快速切換)，特在網上找了一些 RPM 命令的用法，記錄如下。
● 查看內存裏面的進程名字
ps -eLf | more 一頁一頁地查看 (不光進程，線程也會列出來，注意中間那個L是大寫字母)
================================
● 一般常用的 安裝命令就是 rpm -ivh 軟件包名.rpm
● rpm 強制刪除 rpm -e 軟件包名 --nodeps
--test 可以用於做演習， 並沒有真正刪除或者安裝進去
● 找出執行文件路徑
which console-kit-daemon
/usr/sbin/console-kit-daemon● 查看該文件屬於哪個 RPM包
rpm -qif /usr/sbin/console-kit-daemon

Summary : System daemon for tracking users, sessions and seats
Description :
ConsoleKit is a system daemon for tracking what users are logged
into the system and how they interact with the computer (e.g.
which keyboard and mouse they use).
It provides asynchronous notification via the system message bus. ● 好了，知道了包大致名稱，尋找一些究竟有多少個和他相關的已經安裝的包
rpm -qa |grep ConsoleKit
ConsoleKit-libs-0.4.1-3.el6.i686
ConsoleKit-0.4.1-3.el6.i686
ConsoleKit-x11-0.4.1-3.el6.i686 ● 用下面這個命令可以看看該安裝報下面究竟都有些什麼文件（列出文件清單）
rpm -ql ConsoleKit-x11-0.4.1-3.el6.i686
/usr/libexec/ck-collect-session-info
/usr/libexec/ck-get-x11-display-device
/usr/libexec/ck-get-x11-server-pid------------------------------------------------------

● 我們有一個安裝包， 在安裝前我們想知道他裏面究竟要安裝哪些文件到我們的系統當中去
