How to list current version...

English Install/Boot/Login
#1

I have two opensuse 10.3 systems and I would like to compare the
installed packages. What command could I use to list the installed
packages. Then I can sort them and compare them.

Hi
Pipe the output from rpm to a file and then use diff to compare;


rpm -qa > machine1.txt
rpm -qa > machine2.txt
diff machine1.txt machine2.txt

Same idea but I do it sometimes and I can suggest some improvements:


rpm -qa | sort > machine1.txt
ssh machine2 rpm -qa | sort > machine2.txt
comm -3 machine[12].txt

This ensures that the outputs are sorted, and displays only the differences, both ways.

/bin/rpm -qa --queryformat
"%{NAME} %{VERSION} %{RELEASE} %{ARCH} %{SUMMARY}
"

Using tabs as a separator you can then easily use sort (etc).

Also… I included ARCH, because it IS possible that two
machines may have the same version BUT different architectures
(remove ARCH if comparing intentionally between very different
architectures). An example is when you have a 64bit capable
x86… someone might install 32bit versions of some packages.
