1. Indentation and Whitespace

Choose an indentation size: Common choices are 2 or 4 spaces. Some styles use tabs, but spaces are generally more consistent across editors.
Indent each new code block: Inside any set of { }, increase the indentation level by one. When you exit that block, decrease the indentation level.

Example (indenting 4 spaces):

	#!/usr/bin/env bash
	#
	# Usage: group.sh target_directory 4
	# Result:
	# target_directory/part1of3/...files from January till April (inclusive)
	# target_directory/part2of3/...files from May till August
	# target_directory/part3of3/...files from September till December
	#

	set -e

	#!/usr/bin/env bash

	FILE=$1
	FILE_ENC="$FILE.enc"

	encrypt() {
	openssl enc -aes-256-cbc -e -in "$FILE" -out "$FILE_ENC" -pass "pass:$PASS"
	}

	decrypt() {
