sh Coding Style

Abstract

cat << END
set -e
snake_case() {
  local foo=bar
  some-command --long-option "$foo"
}
END | dash

Naming

We prefer hyphen-word over snake_case over CamelCase. However, dash only allows _ and alnum as variable names. Thus, snake_case is preferred.

Short options

We prefer --long for self-documentation.

Compatibility

Test against dash.

Fails early

Use set -e.

Local variable

Use local variables in function definitions when possible.
