Linux+ 1.1.3: Architectures, distributions and licenses

Finding the machine architecture and the distribution family, a package's license, and a package that isn't tied to one architecture.

Before you start

The lab sets nothing up. Each task asks for a finding: write it to the file in /root/lab-answers/ that the task names.

Tasks

1. Write the machine architecture on the first line of /root/lab-answers/1, and the distribution family this system says it belongs to (one of the words in ID_LIKE, such as rhel or debian) on the second.
2. Find the license of the bash package and write it to /root/lab-answers/2.
3. Find a package that isn't architecture-specific and write its name to /root/lab-answers/3.

Hints

• uname -m; grep -E '^(ID|ID_LIKE|VERSION_ID)=' /etc/os-release.
• rpm -q --qf '%{NAME}: %{LICENSE}\n' bash on the RHEL family; /usr/share/doc/bash/copyright on Debian and Ubuntu.
• rpm -qa --qf '%{ARCH} %{NAME}\n' | grep ^noarch; dpkg -l | awk '$4=="all"{print $2}'.
