YUM / RPM General

What is installed locally

     yum list installed

     rpm -qa --queryformat '%{NAME}-%{VERSION}-%{RELEASE}:%{SUMMARY}\n' |
        sort | awk -F: '{printf "%-30s %s\n",$1,$2}'

What is on a specific repo

    yum --disablerepo=\* --enablerepo=adobe\* list available

Local Install (yum also gets dependancies)

    yum localinstall /path/to/package-1.0.0-1.i386.rpm

Dependancies (requires and is required by)

    rpm -q --requires xyzzy
    rpm -q --whatrequires xyzzy

What package will install file or library "xyzzy"
  (if needed by another package).
  Install the rpmdb-redhat  package  then use

    rpm -q --whatprovides xyzzy
    rpm -q --redhatprovides xyzzy

-------------------------------------------------------------------------------
General RPM

List package and info
   rpm -qilp {package}.rpm

What dependancys (requirements) does it need
   rpm -qRp {package}.rpm

Install with progress bar
   rpm -ihv  {package}.rpm

Follow dependancys (in same directory, using "rpmdb" database)
   rpm -hiv --aid {package}.rpm

Reset file permissions of installed Package
  rpm --setperms {package}
Reset ownership
  rpm --setugids {package}

Reset permissions on all install packages
  for p in $(rpm -qa); do rpm --setperms $p; done
  for p in $(rpm -qa); do rpm --setugids $p; done

Checksum installed files
test string:  S:size  M:mode(perms/type)  5:md5sum   T:time
file type:  c:config  d:doc r:readme

  rpm -Vf /etc/profile

General YUM

Clean up Cache

   sudo yum clean all
   sudo yum makecache

Install package
   sudo yum install xine

Local copy
   sudo yum localinstall ImageMagick-6.2.5-5.i386.rpm

Remove it and any dependancys nolonger in use
   sudo yum remove rhythmbox

Install package_group
   sudo yum groupinstall 'MySQL Database'

Update All
   sudo yum update

Update just package
   sudo yum update xine

List available packages

   yum list xine
   yum list '*mp3*'
   yum grouplist

List description for a package
   yum info junit

search for string in package name and description

   yum search mp3

look for a package providing a library

   yum provides libneon

Turn on auto updates...
   chkconfig yum on
   service yum start

NOTE: this does not actually run a service, it just enables the
"/etc/cron.daily/yum.conf" cron job to auto-update the system at 4am


-------------------------------------------------------------------------------
Downgrade Packages

  yum downgrade firefox
    dependancy hell

  rpm -Uvh --oldpackage packagename

When updating skip packages and associated packages
  yum --exclude=firefox --skip-broken update

-------------------------------------------------------------------------------
RPM from SRPM sources

Build a RPM directly from a source RPM
   rpmbuild --rebuild  {package}.src.rpm
Then install
   rpm -ihv ~/rpmbuild/RPMS/i386/{package}.i386.rpm

NOTE: yum can NOT download SRPM packages at this time.

Build step by step
  package=???

  # get sources
  rpm -ihv $package-*.src.rpm
  yum-builddep $package

  # %files -- check all prerequesite files are avaiable
  rpmbuild -bl ~/rpmbuild/SPECS/$package.spec

  # %prep -- extract / apply all patches -- in /usr/src/redhat/BUILD
  rpmbuild -bp ~/rpmbuild/SPECS/$package.spec

  # %build -- compile the binaries patched (above and manually) sources
  rpmbuild --short-circuit -bc ~/rpmbuild/SPECS/$package.spec

  # %install -- install the just built binaries
  rpmbuild --short-circuit -bi ~/rpmbuild/SPECS/$package.spec

  # Unpack and build the appropriate RPM's from installed package
  rpmbuild -bb ~/rpmbuild/SPECS/$package.spec

  # Rebuild SRPM source package (after changes to patching or sources tar)
  rpmbuild -bs ~/rpmbuild/SPECS/$package.spec


Clean out the whole source area

  rm -rf ~/rpmbuild


Build a RPM that will install into a different prefix??? -- untested
  rpmbuild --define="_prefix /opt/MyApps/ImageMagick"   spec_file


To prevent RPM from stripping debug infomation either
Add to "spec" file
  %define __os_install_post %{nil}
or in the install section export this variable
  export DONT_STRIP=1
or disable the script that calls it
On fedora systems that is  /usr/lib/rpm/find-debuginfo.sh

-------------------------------------------------------------------------------
Unpackage RPM without installing...

   mkdir t
   cd t
   rpm2cpio .../RPM.rpm | cpio -idmv

-------------------------------------------------------------------------------
RPM from TAR source
Found on GQview web site, how this workes is another matter.
When complete, the new binary package can be found in /usr/src/redhat/RPMS/i386

  rpm -tb xxx-x.x.x.tar.gz

-------------------------------------------------------------------------------
Create 'os' yum repository from DVD

  echo '
    | [fedora-dvd]
    | name=Fedora DVD (for $releasever)
    | baseurl=file:///media/Fedora%20$releasever%20i386%20DVD/
    | enabled=0
    ' | sed -n '/^ *|/!d; s/^ *|//; s/^ //; p' > FILE

  yum --disablerepo=\* --enablerepo=fedora-dvd list available

Install original kernel from DVD

  yum --disablerepo=\* --enablerepo=fedora-dvd install \
    kernel kernel-PAE kernel-headers kernel-devel kernel-PAE-devel
