###mapbbox.js outputs a .png image using the Web Mercator (EPSG: 3857) projection

./mapbbox.js -h 480 -w 640 \                           #dimensions of output image (px)

-b $LON1,$LAT1,$LON2,$LAT2 \ #bounds: lon1,lat1,lon2,lat2

$1, $2, $3, ... are the [positional parameters][1].
"$@" is an array-like construct of all positional parameters, {$1, $2, $3 ...}.
"$*" is the IFS expansion of all positional parameters, $1 $2 $3 ....
$# is the number of positional parameters.
$- current options set for the shell.
$$ pid of the current shell (not subshell).
$_ most recent parameter (or the abs path of the command to start the current shell immediately after startup).
$IFS is the (input) field separator.
$? is the most recent foreground pipeline exit status.
$! is the PID of the most recent background command.

Last command's parameters: !* TAB
Last command's first parameter: !^ TAB
Last command's last parameter: !$ TAB

Example: You have a branch refactor that is quite different from master. You can't merge all of the commits, or even every hunk in any single commit or master will break, but you have made a lot of improvements there that you would like to bring over to master.

Note: This will not preserve the original change authors. Only use if necessary, or if you don't mind losing that information, or if you are only merging your own work.

On master:

> git co -b temp

	import arcpy
	import json
	from arcpy import env

	env.workspace = "E:/master_regions_unpacked"
	txtFile = open("E:/master_regions/regionArray","w")
	txt = []
	files = arcpy.ListFiles("*.dbf")
	for file in files:
	txt.append("'"+str(file).split(".")[0]+"'=>array(")

	$.fn.swapClass = function(a, b) {
	if (a && b) {
	this.toggleClass(a).toggleClass(b);
	} else {
	let arr = this.selector.split(',');
	if (arr.length < 2) {
	return this;
	}
	return this.swapClass(arr[0].substr(1), arr[1].substr(1));
	}

	EPSG: 4326 uses a coordinate system on the surface of a sphere or ellipsoid of reference.
	WGS 84 - Earth as Geoid. -Mercator

	EPSG: 3857 uses a coordinate system PROJECTED from the surface of the
	sphere. Earth as perfectly sphere. -Web Mercator

	Think of it as this way:

	EPSG 4326 uses a coordinate system the same as a GLOBE (curved surface).
	EPSG 3857 uses a coordinate system the same as a MAP (flat surface).
