Hey guys. Been really wanting to get into learning the Linux command line lately, especially because I want to be able to build my os foundation from the ground up (Features and such). The only thing I've been wary of is losing compatibility with programs I normally use such as packet tracer and a couple others. What do you think would be the best distro for me to help construct that foundation for me, and where would be the best resources for me to begin such a feat? Any help would be appreciated?
