Re: How to test the presence of packages ?

If you need a simple script logic, you could use bash like this:


PACKAGES="package1 package2 package3"

for PACKAGE in ${PACKAGES}; do

        dpkg -l ${PACKAGE} > /dev/null 2>&1

        if [ !$? ]; then
                aptitude install ${PACKAGE}

Now, if you need this at package level, you should listen to Pietro's
