Checking for installed packages and if not found install

Question

I need to check for installed packages and if not installed install them.

Example for RHEL, CentOS, Fedora:

rpm -qa | grep glibc-static
glibc-static-2.1         


        

Answer 1

Based on @GillesQuenot and @Kidbulra answers, here's an example how to loop over multiple packages, and install if missing:

packageList="git gcc python-devel"

for packageName in $packageList; do
  rpm --quiet --query $packageName || sudo yum install -y $packageName
done
