[SOLVED] A noob qn regarding Package managers.

maobin · 02-28-2011, 09:37 PM

Hi all,
I have a noob qn, if I installed a program with yum, will I be able to see the details of the installed program with rpm -qa?

My linux has no internet access so I can't test it out.

Yes. yum uses rpm in the background.

Is there any package manager that doesnt use rpm as background? or it is a must to use rpm as a background?

Not exactly sure what you mean.

Debian-based systems use apt; the packages are named *deb. *.deb packages and *.rpm packages are not interchangeable.

Arch uses its own package manager, pacman.

Slackware just quietly goes its own steady reliable way.

In any case, you can always compile from sources without bothering with a package manager, but then you may run into dependency issues.

This Wikipedia article is a good summary of package managers and formats:

If you're interested in rpm/yum cmds, try this http://kbase.redhat.com/faq/docs/DOC-2531

so does it mean that red hat only has yum and rpm?

sumeet inani · 02-28-2011, 11:34 PM

yeah , red hat needs rpm file or source tarball to install software.
My friend had red hat without subscription support so he could not access repository for easy installation of software.
I suggest that you try cent OS which is similiar to red hat without hassles of compiling from source or locating desired rpm's as its repository is free .

Thanks for the advice

1)yum used in Fedora, CentOS-5, Red Hat Enterprise Linux 5 and above, Scientific Linux, Yellow Dog Linux and Oracle Enterprise Linux

2)up2date used in Red Hat Enterprise Linux and CentOS (CentOS-3 and CentOS-4).

I pulled this from wiki, so other than yum there is also other package manager like up2date. It is true that all the front ends will have to use rpm somehow?

You are using an rpm based OS. All packages are "rpm packages" !

The install command used by yum (and the GUI tools) is 'rpm -Uvh <package>.rpm'.
( 'up2date' is a very old tool : Only used in some old EL4 / CentOS4.)
( EL3 / CentOS3 is obsoleted.)
