rpm - red hat package management command allows you to install (-i) 
	**RPM is an applications that runs on several different
	platforms to install modular software*** 

	query(-q) verify, build etc software packages in red hat
	linux.

	example: rpm -aq  -will print all the packages installed
		rpm -q ppp  -would print out wether the ppp pkg was installed

	simular to pkgadd - pkgrm - pkinfo in Solaris

An example of installing module "mkbootdisk" from a cdrom ****************
I actually installed mkbootdisk from an external drive, see below for syntax 

To gain access to this file, you'll first need to mount your Red Hat Linux
CD-ROM.  Start by inserting the CD-ROM in your system's CD-ROM drive.
You'll need to do this while logged in as root.  Issue the following
commands:

                             mkdir /mnt/cdrom
                        mount /dev/cdrom /mnt/cdrom

You may get an error message from the first command saying that the file
exists.  That's fine; we just want to make sure that there is a /mnt/cdrom
directory on your system.  The second command should issue an informational
message that /dev/cdrom is being mounted read-only (Note: some systems may
not recognize /dev/cdrom.  If this is the case, you'll have to replace
/dev/cdrom with the appropriate device name for your CD-ROM).

Next, issue the following commands (again, while logged in as root):

                           cd /mnt/cdrom/images
                                    ls

You should see a file with a name similar to:

mkbootdisk-1.0-1.i386.rpm

Enter the filename *exactly* as shown at the end of an "rpm -Uvh".  For
example:

                    rpm -Uvh mkbootdisk-1.0-1.i386.rpm

The name of the package (mkbootdisk) will be displayed, followed by a
series of pound signs (#).  After a short time, you'll get a shell prompt.
The mkbootdisk package is now installed.  No you can head back to the place
in this document where you left off, and create your boot diskette.

		The actual install
This also shows upgrading and installing from source rpm

[root@rachel SRPMS]# pwd
/mnt/Redhat/SRPMS
[root@rachel SRPMS]# rpm -Uvh mkbootdisk-1.0-2.src.rpm

A simple install of the AfterStep RPM
[root@sparky2 RPMS]# ls |grep -i after

[root@sparky2 RPMS]# rpm -i AfterStep-1.4.5.3-2.sparc.rpm

To query a machine about the rpms install	rpm -qa


More on options:

Install mode:
           rpm -i [install-options] <package_file>+
       Query mode:
           rpm -q [query-options]
       Verify mode:
           rpm -V|-y|--verify [verify-options]
       Signature Check mode:
           rpm --checksig <package_file>+
       Uninstall mode:
           rpm -e <package_name>+
       Build mode:
           rpm -[b|t]O [build-options] <package_spec>+
       Rebuild database:
           rpm --rebuilddb
       Fix permissions:
           rpm --setperms [query-package-specifiers]
       Set owners and groups:
           rpm --setugids [query-package-specifiers]
       Show RC:
           rpm --showrc
           
           The general form of an rpm install command is

            rpm -i [install-options] <package_file>+

       This  installs  a new package.  The general form of an rpm UPGRADE
       command is
		UPGRADE a package
            rpm -U [install-options] <package_file>+
  
Build an rpm from a src-rpm file

	Locate src-rpm:
cd /home/keeng1/
  
cd download	<--- this is where you downloaded it to
ls
mkisofs-1.12b5-6.src.rpm

	As root, create the rpm package:
rpm --rebuild mkisofs-1.12b5-6.src.rpm
  	This will compile the code, so must have the 
	apropreiate compiler and libraries available.
	
	As root, install the rpm:
cd /usr/src/redhat/RPMS/i386/
ls
mkisofs-1.12b5-6.i386.rpm
rpm -i mkisofs-1.12b5-6.i386.rpm
which mkisofs
/usr/bin/mkisofs

	I have been looking for a way to use rpm cmd to look
at an uninstalled rpm and find out what it is, and a short 
discription. Finially -------  rpm -qpi uninstalled.rpm

rpm -q(query) -p(package file uninstalled, could be a ftp or http site)
	-i(display package info)

	I believe the key is the  -p  option, I think you could use
	other option for other info besides the   -i option.
	example:	
	-l  option will list files in package.
	-R  prints out the files required for package to be installed
t
	    and function.


#--------------------- Remove, uninstall an RPM ------------------------#

Uninstall an rpm

UNINSTALL OPTIONS
       The general form of an rpm uninstall command is

                rpm -e <package_name>+

       --allmatches
              Remove all versions  of  the  package  which  match
              <package_name>.  Normally  an  error  is  issued if
              <package_name> matches multiple packages.

       --noscripts
              Don't execute  the  preuninstall  or  postuninstall
              scripts.

       --notriggers
              Don't  execute  scripts  which are triggered by the
              removal of this package.

       --nodeps
              Don't check dependencies  before  uninstalling  the
              packages.

       --test Don't  really  uninstall  anything, just go through
              the motions.  Useful in conjunction  with  the  -vv
              option.
