All, I am now building rpms on, and using a multi-lib arch (x86_64) for the first time ... when using the standard command: rpm -qa | grep pkg_name The results might be pkg_name.i386 or pkg_name.x86_64 ... or both. But, the way it is shown by the default query format, looks the same ... like this: pkg_name pkg_name ---------------------------- example: [root at x86-64 ~]# rpm -qa | grep popt popt-1.9.1-21 popt-1.9.1-21 ---------------------------- To fix this problem on multi-lib machines (and change the default query format), you can change your .rpmmacros (or create a .rpmmacros) in your user home directory and add this line: %_query_all_fmt %%{name}-%%{version}-%%{release}.%%{arch} --------------------------- Now the result of the above example is: [root at x86-64 ~]# rpm -qa | grep popt popt-1.9.1-21.x86_64 popt-1.9.1-21.i386 --------------------------- So now you can easily tell which arch of a program is installed on multi-lib machines. Thanks, Johnny Hughes
