Example: Determining the installed version of gcc

To see whether gcc is installed on SLES or RHEL, query for the gcc package as follows:

   rpm -q gcc

If gcc version 4.8-5.3 is installed, you will get a result similar to the following output:

   gcc-4.8-5.3

To see whether gcc is installed on Ubuntu, query for the gcc package as follows:

   dpkg -l gcc

If gcc version 4.8.2-1ubuntu4 is installed, you will get a result similar to the following output:

  Desired=Unknown/Install/Remove/Purge/Hold
