I was looking to do some quick calculations from the Linux console today and discovered ‘bc‘.

Example Command:

• echo ‘1028 * 8’ | bc

I can see how this command could be useful in a shell script!!

I just spun up a RHEL instance and noticed my DHCP Client was not starting on boot.

Simplest solution for me was to update my NICs interface file with “ONBOOT=yes” and ensure “BOOTPROTO=dhcp” was set.
