RPM Package Manager
Rpm is the Redhat Package Management system. By using rpm utility the user can instal new packages or upgrade and can also remove existing packages.

Here vsftpd is the name of package & 2.0.6-0.el6 is the version of package & i386 is the type of architecture of the package & .rpm is the extension.

To install rpm:

#rpm –force –aid

options:

-i  =  install
-v  =  verbose
-h  =  to display progress in hashes
–force = to install forcefully
–aid    = to install packages with dependencies

ex: rpm  -ivh  nfs-utils   –force  –aid
rpm  -ivh  nfs-utils-lib  –force  –aid

To upgrade:

#rpm

options:
-U  =  upgrade
-v  =  verbose
-h  =  to display in hashes

eg: rpm -Uvh  nfs-utils
rpm -Uvh  nfs-utils-lib

To remove an rpm:

#rpm –nodeps

options:
-e  = to remove package from the system
–nodeps =  remove without dependencies

eg: # rpm -e nfs-utils   –nodeps

To query rpm package:

# rpm

options:
-q    =   to query the availability of installed package
-qa  =  queries all installed rpm’s in o/s
-qc  =  list only configuration files stored in queried rpm
-qd  =  list only doc files stored in queried rpm
-qi   =  displays complete information about queried rpm
-qs  =  displays status of files in queried rpm
-ql   =  displays files related to queried rpm
-qf   =  query find of the package
Eg :- To display information of Package
