Yum Command Line Options
What is YUM?
YUM (Yellowdog Updater Modified) is the primary tool for getting, installing, deleting, querying, and managing RPM software packages based on Linux machines. Yum can be installed using various third party repositories over the network.
[1] Checking for Updates:
To check which installed packages having available updates on your system:
[stextbox id=”Default” mode=”css” bwidth=”7″ color=”FFFFFF” ccolor=”000000″ bcolor=”1A52EA” bgcolor=”000000″ bgcolorto=”000000″ image=”null”]
[root@quickfixlinux ~]# yum check-update [/stextbox]
[2] Updating the packages are available in different ways, as like updating the entire package, single package or multiple packages at once.
[2.1] Updating the Single package:
[stextbox id=”Default” mode=”css” bwidth=”7″ color=”FFFFFF” ccolor=”000000″ bcolor=”1A52EA” bgcolor=”000000″ bgcolorto=”000000″ image=”null”]
[root@quickfixlinux ~]# yum update nmap [/stextbox]
[2.2] Updating the multiple packages:
[stextbox id=”Default” mode=”css” bwidth=”7″ color=”FFFFFF” ccolor=”000000″ bcolor=”1A52EA” bgcolor=”000000″ bgcolorto=”000000″ image=”null”]
[root@quickfixlinux ~]# yum update rpm nmap perl python [/stextbox]
[2.3] Updating entire packages:
[stextbox id=”Default” mode=”css” bwidth=”7″ color=”FFFFFF” ccolor=”000000″ bcolor=”1A52EA” bgcolor=”000000″ bgcolorto=”000000″ image=”null”]
[root@quickfixlinux ~]# yum update [/stextbox]
[3] Updating Security Related patches:
If you really want to update only the security related patches to the latest version:
[stextbox id=”Default” mode=”css” bwidth=”7″ color=”FFFFFF” ccolor=”000000″ bcolor=”1A52EA” bgcolor=”000000″ bgcolorto=”000000″ image=”null”]
[root@quickfixlinux ~] # yum update – –security [/stextbox]
You can also update packages only to the version contains the latest security updates:
[stextbox id=”Default” mode=”css” bwidth=”7″ color=”FFFFFF” ccolor=”000000″ bcolor=”1A52EA” bgcolor=”000000″ bgcolorto=”000000″ image=”null”]
[root@quickfixlinux ~]# yum update-minimal – –security [/stextbox]
For example, assume that: the kernel-3.10.0-1 package is installed on your system; the kernel-3.10.0-2 package was released as a security update; the kernel-3.10.0-3 package was released as a bug fix update. Then yum update-minimal – –security updates the package to kernel-3.10.0-2, and yum update – – security updates the package to kernel-3.10.0-3.
