RPM Question

[Kyle D. Harris]

I just tried applying a patch with "rpm -ivh filename.rpm" and it said it conflicted with a previous version installed. So i did rpm -Uvh filename.rpm and it went smooth.

My question is I don't understand what the -U or update fully does. Does it basically install or overwrite that file over the previous one that was installed? Thanks in advance!

More than that !

It checks the old package install, overwrite what is written at the same place, and remove what is not necessary anymore ! A pure command, as we say here !

When doing the RHCE course, the RedHat guy actually suggested that the use of 'i' as a flag was mostly unnecessary, as 'U' would do the same, if not better than 'i'.

Go figure. I'm still of the mind to use 'i' when installing stuff though.

it's simple:

-i install new version without remove old

-U, -F install new version and remove old (they save changed config-files)


Most manuals recommend use "-i" only for kernel packages in order to save old kernel.

For other packages you can use -U and -F.
