RPM + rpm installation (not create directory according to SPEC)

I need advice about the following

I build simple spec file and build rpm

I transfer the new rpm to other Linux machine in order to install the new rpm

according to the spec file the new rpm -> test.sh-6.2-2.i386.rpm should create the /tmp/MY_RPM_TESTS directory , but this rpm not create the MY_RPM_TESTS and sub directories please advice why , what I need to fix in the spec file?

RPM installation:

   [root@linux1 rpm -Uvh  /root/rpmbuild/RPMS/i386/test.sh-6.2-2.i386.rpm

You misunderstand. /tmp/MY_RPM_TESTS is the build root, which is created, but is only used temporarily and internally by rpmbuild. It is not meant to be part of the rpm file, and you should never try to install anything in /tmp anyway! /tmp is for temporary files only.
