Re: preun/postun argument when multiple instances

[Hiren Patel <patelhn telkom co za>]

i decided to test this for you with a really simple pointless rpm called
test.

the pointless rpms i built are:
test-2-1.rhel4.i386.rpm
test-1-1.rhel4.i386.rpm

each have the following for %pre, %post, %preun, %postun

%pre
echo "pre is $1"
echo "package is 1"

%post
echo "post is $1"
echo "package is 1"

%preun
echo "preun is $1"
echo "package is 1"

%postun
echo "postun is $1"
echo "package is 1"

(where package version 2 says 'package is 2')

results:

[root localhost i386]# rpm -i test-1-1.rhel4.i386.rpm
pre is 1
package is 1
post is 1
package is 1
[root localhost i386]# rpm -i test-2-1.rhel4.i386.rpm
pre is 2
package is 2
post is 2
package is 2
[root localhost i386]# rpm -q test
test-1-1.rhel4
test-2-1.rhel4
[root localhost i386]# rpm -e test-1-1.rhel4 test-2-1.rhel4
preun is 1
package is 2
postun is 1
package is 2
preun is 0
package is 1
postun is 0
package is 1
[root localhost i386]#
