RPMs

Red Hat Package Management


Installing RPMs

# rpm -i packagename

# rpm -ivh packagename
  -v adds verbose feedback, and -h draws progress hashmarks

# rpm -ivh --test packagename

Upgrading RPMs

# rpm -Uvh packagename

To test the package install without really installing it.
# rpm -Uvh --test packagename


Removing RPMs

#rpm -e packagename does the job 

# rpm -ev packagename

( You dont need to mention the entire package, (abcd-1.23.34.5.i386.rpm) just the label name (abcd).


Removing/Uninstalling multiple RPMs at once.

# rpm -ev packagename packagename packagename


If you dont want to check dependencies,

#rpm -ev --nodeps packagename


To test your command before uninstalling/removing
#rpm -ev --test packagename


Collecting information on Installed RPMs
Use RPM's querying features.  All the queries start with rpm -q.
# rpm -q compiz

# rpm -qa | grep ubuntu

Listing files in an installed package

# rpm -ql compiz



To list the documentation for an application, use

# rpm -qd ubuntu

To list the configuration files for a package, use

# rpm -qc compiz

Listing the configuration files for a command

# rpm -qcf /usr/bin/ssh


To list all the packages installed, use

# rpm -qa

To see what package a file belongs to, use

# rpm -qf /usr/bin/abcd

To display package information 

# rpm -qi packagename


RPM queries will not follow symlinks, and will report that the file is "not owned by any package"  To find the file that a symlink points to , use:

# namei ~/ronak

Collecting Information from RPMs that are not installed.

Listing documentation files
# rpm -qpd abcd.rpm


Listing all the files of the package:

# rpm -qp1 abcd.rpm

Listing dependencies this package requires, 
# rpm -qpR abcd.rpm


To see what this package provides

# rpm -qp --provides abcd.rpm


Finding recentally installed RPMs

# rpm -qa --last
If the list is too long, rpm -qa --last | head.


Rebuild RPM database

# rpm --rebuilddb


Recreate RPM database
# rpm --initdb
