Redhat – yum simulate install

package-managementredhat

Coming from an ubuntu perspective, if I want to check to see what additional packages will be installed/upgraded I can use apt-get --simulate install <package name>

Is there something similar for yum? Our Red hat box (yum) is our production server, so I would like to see exactly what will be happening before I actually install some package.

Couldn't really find a good solution, someone suggested:

yum --assumeno install <package name>

but this returned:

Command line error: no such option: --assumeno

yum version: 3.2.22

OS version: Red Hat Enterprise Linux Server release 5.6 (Tikanga)

Any ideas or suggestions would be welcome.

Best Answer

you can do a yum install without the -y switch (if you use it):

yum install <package>

this will grab a list of packages and dependancies required. Before installing it will ask you if you want to install or not, just answer no and no changes will be made.

Alternatively you can do 

yum deplist <package>

to list all the dependancies of a package and see what needs to be installed without downloading or installing anything.
