## Dynamic aliases
By running the follow code, it will check to see what programs are already installed on your OS (based on your `$PATH`), and echo out the result. This could then be added to your shell resource file as a one off. Alternatively, by removing the `echo` in the code, it could be placed into your shell resource file directly, and it will create the necessarily aliases each time:
for cmd in g++ gas head make ld ping6 tail traceroute6 $( ls /usr/share/grc/ ); do
cmd="${cmd##*conf.}"
type "${cmd}" >/dev/null 2>&1 && echo alias "${cmd}"="$( which grc ) --colour=auto ${cmd}"
