Shell

• Break long lines on |, &&, or || and indent the continuations.
• Don't add an extension to executable shell scripts.
• Don't put a line break before then or do, use if ...; then and while ...; do.
• Use for x; do, not for x in "$@"; do.
• Use snake_case for variable names and ALLCAPS for environment variables.
• Use single quotes for strings that don't contain escapes or variables.
• Use two-space indentation.
