How to list RPM dependencies?

Question

Our production server is running CentOS release 5.2 (Final).

How do I see/get/list all the dependencies of an already installed RPM package?

For example: SQLite v3.3.6 is already installed in the server. I want to see all the dependencies of this particular package.

Here is the output of the command: rpm -qa |grep sqlite

python-sqlite-1.1.7-1.2.1
sqlite-3.3.6-2
sqlite-3.3.6-2

Also, why it is listing 2 entries of sqlite-3.3.6-2 here?

Answer 1

1. rpm -q --requires somepackagehere

2. One is the i?86 package, the other is the x86_64 package.

Answer 2

The yum deplist command will show you which rpm is required:

# yum deplist expect
..
..
package: expect.i386 5.43.0-5.1
 dependency: libc.so.6
  provider: glibc.i686 2.5-49
  provider: glibc.i686 2.5-49
 dependency: libtcl8.4.so
  provider: tcl.i386 8.4.13-4.el5

Answer 3

Following on Ignacio's answer, you can see the specific architecture of the packages by doing the following:

$ rpm -qa --queryformat "%{NAME} %{ARCH}\n" sqlite
sqlite i686

In my case, I only have the one, i686 package...but you can get the architecture associated with the packages that way. If you are interested in what else you can get from the --queryformat, issue a rpm --querytags to see the list of variables available.
