Hi.

Regrettably, rpm does not return an exit status as do most commands (more correctly it seems to always return zero). This might be because it's too complex to simply decide "yes" or "no".

So one solution is to look at the output. We can do a compare very similar to the way you did, but checking for a string match, rather than strict equality, which can cause problems because of whitespace, among other things.

Here's an example:
Code:
#!/bin/bash -

# @(#) user1    Demonstrate rpm query.

uname -rv
bash --version
rpm --version

echo
P=${1?" must specify package name."}

rpm -qa "$P" > t1
my_size=$( wc -l < t1 )
echo " Size of report file is $my_size lines"

if [[ $( rpm -qa $P ) =~ ${P} ]]
# if [[ $( rpm -qa $P ) == *${P}* ]]
then
  echo " Package $P is installed."
else
  echo " Package $P not found."
fi

exit 0

Producing a success:
Code:
./user1 bash
2.6.22.17-0.1-default #1 SMP 2008/02/10 20:01:04 UTC
GNU bash, version 3.2.25(1)-release (i586-suse-linux-gnu)
Copyright (C) 2005 Free Software Foundation, Inc.
RPM version 4.4.2

 Size of report file is 1 lines
 Package bash is installed.

And a failure:
Code:
./user1 junk
2.6.22.17-0.1-default #1 SMP 2008/02/10 20:01:04 UTC
GNU bash, version 3.2.25(1)-release (i586-suse-linux-gnu)
Copyright (C) 2005 Free Software Foundation, Inc.
RPM version 4.4.2

 Size of report file is 0 lines
 Package junk not found.

You can look a the output from rpm on file t1. Both forms of the "if" seemed to work for me, and you can look through man bash or a tutorial to see the details on the "if" ... cheers, drl

scap-as-rpm(8)						  System Administration Utilities					    scap-as-rpm(8)

NAME

       scap-as-rpm - manual page for scap-as-rpm

DESCRIPTION

       usage: scap-as-rpm [-h] [--pkg-name PKG_NAME] [--pkg-version PKG_VERSION]

	      [--pkg-release   PKG_RELEASE]   [--pkg-summary  PKG_SUMMARY]  [--pkg-license  PKG_LICENSE]  [--pkg-scap-location	PKG_SCAP_LOCATION]
	      [--rpm-destination RPM_DESTINATION] [--srpm-destination SRPM_DESTINATION] FILE [FILE ...]

       Takes given SCAP input(s) and makes an RPM package that contains them. The result  RPM  can  be	installed  using  #  yum  install  ./pack-
       age-name-1-1.rpm which will put the contents into /usr/share/xml/scap. No dependency on openscap or scapworkbench is enforced in the output
       package so you can use any SCAP-capable scanner to evaluate the content.

   positional arguments:
       FILE   List of files that should be put into the result package. These should be SCAP XML files but such requirement is not enforced.

   optional arguments:
       -h, --help
	      show this help message and exit

       --pkg-name PKG_NAME
	      Name of the RPM package, if none is provided the basename of the first SCAP input is used. Ex.: xyzsecurity-guide

       --pkg-version PKG_VERSION

       --pkg-release PKG_RELEASE

       --pkg-summary PKG_SUMMARY
	      Optional short description of the package.

       --pkg-license PKG_LICENSE
	      Short name of the license that you want to publish the package under. Ex.: GPLv2+, BSD, ...

       --pkg-scap-location PKG_SCAP_LOCATION
	      Folder where SCAP files are supposed to be installed.  Each package will have its own folder inside this folder. RPM  variables  can
	      be used and will be expanded as usual. It is recommended to keep the default settings.

       --rpm-destination RPM_DESTINATION
	      The folder (absolute or relative to CWD) where the result RPM shall be saved.

       --srpm-destination SRPM_DESTINATION
	      The folder (absolute or relative to CWD) where the result SRPM shall be saved.
