1. Show commandline name instead of shortened command line …

   /proc/pid/cmdline holds the complete command line for a process unlike
   /prod/pid/comm
   
   The biggest difference when using cmdline vs comm is the following, when
   running an app via update-alternatives as done with Debian for example,
   you get the name x-terminal-emulator vs x-terminal-emul. Essentially, we
   want the full name of the process and not the shortened one.
   
   This would allow for some more magic with which, readlink and basename
   that to get the actual name. However, readlink isn't available on all
   systems and some options aren't available on BSD systems. realpath might
   be used, but also that may not be available, which leaves us with
   implementing a bash only solution in case these do not exist. I've tried
   doing that with bash (via bats) in the past. Bats solved it doing it
   like this: bats-core/bats-core#312
   
   An alternative way is to ls the file /proc/id/exe and look at where
   this symlink is pointing to and basename that:
   
     $(basename ls -l /proc/2464281/exe | awk '{print $NF}')
