Yes, it's about 250 lines, and if you have links installed you could do something like this instead:
bashwiki() {
links -dump "https://en.wikipedia.org/wiki/$@" | head -n 60
}
And call it with `$ bashwiki golang` and you get the summary (and some of the other text). My guess is that someone a little more familiar with bash could strip the extra output and make it a bit nicer though.
As they say "to each his own" :)
