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-2.12-1.80.el6_3.5.i686
How do I do a check in BASH?
Do I do something like?
if [ "$(rpm -qa | grep glibc-static)" != "" ] ; then
And what do I need to use for other distributions? apt-get?

Answer
Try the following code :
if ! rpm -qa | grep -qw glibc-static; then yum install glibc-static fi
or shorter :
rpm -qa | grep -qw glibc-static || yum install glibc-static
For debian likes :
dpkg -l | grep -qw package || apt-get install package
For archlinux :
pacman -Qq | grep -qw package || pacman -S package
