yum uses [RPM][1], so the following command will list the contents of the installed package:

    $ rpm -ql package-name


  [1]: https://en.wikipedia.org/wiki/RPM_Package_Manager

Not in Linux at the moment, so can&#39;t double check, but I think it&#39;s:

    rpm -ql ffmpeg

That should list all the files installed as part of the ffmpeg package.

I don&#39;t know about yum, but `rpm -ql` will list the files in a particular .rpm file. If you can find the package file on your system you should be good to go.

I&#39;ve installed ffmpeg using yum under Redhat, and I&#39;m having difficulty figuring out where (what path) it installed the package to. Is there an easy way of determining this without resorting to finding it myself manually?

I want add the date next to a filename (&quot;somefile.txt&quot;). For example: somefile_25-11-2009.txt or somefile_25Nov2009.txt or anything to that effect

Maybe a script will do or some command in the terminal window. I&#39;m using Linux(Ubuntu).

Thanks in advance.

oh i almost forgot to add that the script or command should update the filename to a new date everytime you want to save the file into a specific folder but still keeping the previous files. So there would be files like this in the folder eventually: filename_18Oct2009.txt , filename_9Nov2009.txt , filename_23Nov2009.txt

I installed the newer version of python (3.2.3) than the one available in Fedora16 (python2.7)

And now `yum` stops working. It shows the following error.

      File &quot;/usr/bin/yum&quot;, line 30
       except KeyboardInterrupt, e:

Please advice as how to resolve the error. It would be helpful as I am not able to update or install any package.

I just started using New Relic RPM with my rails app, and one of the metrics they provide is &quot;Throughput RPM&quot;. I have googled everywhere and thoroughly combed the New Relic docs, and I cannot find ANY written explanation of the RPM throughput metric.

Is it &quot;requests per minute&quot; or &quot;requests per millisecond&quot; or something else? **** combustion engines and revolutions per minute make this impossible to find answers about in Google.

**What is throughput RPM? Is a good number higher or lower, what are some average benchmarks, etc?**

I&#39;d greatly appreciate an explanation of this metric, thanks!!

Rails + New Relic: What does RPM mean?

I have built two RPM packages

 - `proj1-1.0-1.x86_64.rpm`
 - `libtest1-1.0-1.x86_64.rpm`

`proj1` depends on the file `libtest1.so` being present and it is reflected correctly in the RPM packages as seen here:

    user@my-pc:~$ rpm -qp --requires proj1-1.0-1.x86_64.rpm
    libtest1.so()(64bit)

    user@my-pc:~$ rpm -qp --provides libtest1-1.0-1.x86_64.rpm
    libtest1.so()(64bit)

The installation of `proj1` fails due to a missing dependency.

    user@my-pc:~$ rpm -ivh proj1-1.0-1.x86_64.rpm
    error: Failed dependencies:
	libtest1.so()(64bit) is needed by proj1-1.0-1.x86_64.rpm

How do I ensure that `libtest1-1.0-1.x86_64.rpm` is installed automatically during
the installation of `proj1-1.0-1.x86_64.rpm`?

I did try the `--aid` option with `rpm -i` as described [here](http://www.redhat.com/advice/tips/rhce/rpm.html) but it didn&#39;t work for me.

Is there any other way?

Thanks for any help.

How to make rpm auto install dependencies

I have an rpm and I want to treat it like a tarball. I want to extract the contents into a directory so I can inspect the contents. I am familiar with the querying commands of an uninstalled package. I do not simply want a list of the contents of the rpm. i.e.

    $ rpm -qpl foo.rpm

I want to inspect the contents of several files contained in the rpm. **I do not want to install the rpm.** I am also aware of the rpms ability to do additional modifictions in the %post sections, and how to check for those. i.e.

    $ rpm -qp --scripts foo.rpm

However in this case that is of no concern to me.

I want to list all packages I have installed on a system from a given repo using yum. Usually to do this I use `yum list installed | grep &quot;something&quot;`. But now I am faced with a problem. The repo I am interested in does not have that &quot;something&quot; for me to grep. The packages from that repo do not have any distinctive characteristics. How do I list them? 

I looked through yum man pages but did not find anything. I wonder if there are other commands I could use.


How to list installed packages from a given repo using yum

I&#39;m trying *not* to learn much about either yum or maven.  I&#39;ve inherited this code and I don&#39;t want to spend more time than I have to in this environment.

I&#39;ve got yum.  My installation &quot;has&quot; (&quot;is attached too&quot;? &quot;knows about&quot;?) two repos: the Amazon one and JPackage, which I understand is something of a standard.  (Actually, each of those repositories consists of two sub-repositories, but I don&#39;t think that&#39;s causing the problem.)

When I asked yum to install maven2, it declined, saying it had never heard of maven2.

When I asked yum to install maven2 *ignoring Amazon*, it does so, but it installs Maven 2.0.9, which is fairly old.  The actual pom.xml I have requires a higher version.

When I Google for Maven repositories I get repositories that Maven can use to build other things, not repositories that Yum can use to install Maven.  (I did find a repository containing thing that let Maven build Yum.  I think Google is mocking me at this point.)

So, all I need is the repo *file* that points to a repo that contains whatever I need to install Maven 2.2.1. 

If it weren&#39;t for all these labor-saving devices, I could probably get some work done.

How do I install Maven with Yum?

I recently installed Python 2.7.3 on a CentOS machine by compiling from source. Python 2.7.3 is installed at /opt/python2.7 and when I installed it I just changed /usr/bin/python to point to the new version. This apparently is wrong though because when I did it it broke yum. I would get the following.

    There was a problem importing one of the Python modules
    required to run yum. The error leading to this problem was:

       No module named yum

    Please install a package which provides this module, or
    verify that the module is installed correctly.

    It&#39;s possible that the above module doesn&#39;t match the
    current version of Python, which is:
    2.7.3 (default, May 15 2012, 17:45:42) 
    [GCC 4.4.4 20100726 (Red Hat 4.4.4-13)]

    If you cannot solve this problem yourself, please go to 
    the yum faq at:
      http://yum.baseurl.org/wiki/Faq


I changed /usr/bin/python to point back to the python 2.6.6 but now 2.6.6 is the default version of python. Any idea how to fix this?
