Today I learned that (TILT) I could edit the .emacs file to start emacs with the various modes turned on.
The default emacs setup that comes with my system (macOS) lacks certain features. The mouse and mouse wheel are not used, there is no word wrap, etc. So I dug through the emacs brain dump via Google and found the following .emacs [^1] modifications:
(xterm-mouse-mode t)
(mouse-wheel-mode t)
(global-visual-line-mode t)
Today I learned that (TILT) I can use xargs and $() to send the output of one command line app to be used as the parameters of the next.
For some reason, I needed the version of make on my macOS. A quick trip to Terminal.app and make --version spits out the required information. But wait, what was this in the corner?
This program built for i386-apple-darwin11.3.0.
So was make an intel binary? file can be used to determine the binary architecture but what was the path to make? Fiddling through the man pages showed me that whence -pa [^1] will find all copies (excluding aliases) of make in my PATH.
