實例 1

安裝 pam-devel

[root@www ~]# yum install pam-devel
Setting up Install Process
Parsing package install arguments
Resolving Dependencies  <==先檢查軟件的屬性相依問題
--> Running transaction check
---> Package pam-devel.i386 0:0.99.6.2-4.el5 set to be updated
--> Processing Dependency: pam = 0.99.6.2-4.el5 for package: pam-devel
--> Running transaction check
---> Package pam.i386 0:0.99.6.2-4.el5 set to be updated
filelists.xml.gz          100% |=========================| 1.6 MB    00:05
filelists.xml.gz          100% |=========================| 138 kB    00:00
-> Finished Dependency Resolution

實例 2

移除 pam-devel

[root@www ~]# yum remove pam-devel
Setting up Remove Process
Resolving Dependencies  <==同樣的，先解決屬性相依的問題
--> Running transaction check
---> Package pam-devel.i386 0:0.99.6.2-4.el5 set to be erased
--> Finished Dependency Resolution

實例 3

利用 yum 的功能，找出以 pam 為開頭的軟件名稱有哪些？

[root@www ~]# yum list pam*
Installed Packages
pam.i386                  0.99.6.2-3.27.el5      installed
