  - ✅ Sources the `default_env.nu` file internally
  - ❌ Does not source the user's `env.nu`
  - ❌ Does not read the internal `default_config.nu` file
  - ❌ Does not read the user's `config.nu` file
  - ❌ Does not read the user's `login.nu` file
  - ✅ Runs the `ls` command and exits
  - ❌ Does not enter the REPL

- `nu -l -c "ls"`:

  - ✅ Makes the Standard Library available
  - ✅ Reads user's `plugin.msgpackz` file if it exists in the config directory
  - ✅ Sources the `default_env.nu` file internally
  - ✅ Sources the user's `env.nu` file if it exists in the config directory
  - ✅ Sources the `default_config.nu` file internally
  - ✅ Sources user's `config.nu` file if it exists in the config directory
  - ✅ Sources the user's `login.nu` file if it exists in the config directory
  - ✅ Runs the `ls` command and exits
  - ❌ Does not enter the REPL

- `nu -l -c "ls" --config foo_config.nu`

  - Same as above, but reads an alternative config file named `foo_config.nu` from the config directory

- `nu -n -l -c "ls"`:

  - ✅ Makes the Standard Library available
  - ❌ Does not read user's `plugin.msgpackz`
  - ❌ Does not read the internal `default_env.nu`
  - ❌ Does not source the user's `env.nu`
  - ❌ Does not read the internal `default_config.nu` file
  - ❌ Does not read the user's `config.nu` file
  - ❌ Does not read the user's `login.nu` file
  - ✅ Runs the `ls` command and exits
  - ❌ Does not enter the REPL

- `nu test.nu`:

  - ✅ Makes the Standard Library available
  - ✅ Reads user's `plugin.msgpackz` file if it exists in the config directory
  - ✅ Sources the `default_env.nu` file internally
  - ❌ Does not source the user's `env.nu`
  - ❌ Does not read the internal `default_config.nu` file
  - ❌ Does not read the user's `config.nu` file
  - ❌ Does not read the user's `login.nu` file
  - ✅ Runs `test.nu` file as a script
  - ❌ Does not enter the REPL

- `nu --config foo_config.nu test.nu`

  - ✅ Makes the Standard Library available
  - ✅ Reads user's `plugin.msgpackz` file if it exists in the config directory
  - ✅ Sources the `default_env.nu` file internally
  - ❌ Does not source the user's `env.nu` (no `--env-config` was specified)
  - ✅ Sources the `default_config.nu` file internally. Note that `default_config.nu` is always handled before a user's config
  - ✅ Sources user's `config.nu` file if it exists in the config directory
  - ❌ Does not read the user's `login.nu` file
  - ✅ Runs `test.nu` file as a script
  - ❌ Does not enter the REPL

- `nu -n --no-std-lib` (fastest REPL startup):

  - ❌ Does not make the Standard Library available

  - ❌ Does not source the user's `env.nu`
  - ❌ Does not read the internal `default_config.nu` file
  - ❌ Does not read the user's `config.nu` file
  - ❌ Does not read the user's `login.nu` file
  - ✅ Enters the REPL

- `nu -n --no-std-lib -c "ls"` (fastest command-string invocation):

  - ❌ Does not make the Standard Library available
  - ❌ Does not read user's `plugin.msgpackz`
  - ❌ Does not read the internal `default_env.nu`
  - ❌ Does not source the user's `env.nu`
  - ❌ Does not read the internal `default_config.nu` file
  - ❌ Does not read the user's `config.nu` file

Title: Detailed Nushell Launch Scenarios and Configuration Loading Behavior
Summary
This section provides a comprehensive breakdown of various Nushell launch scenarios using different command-line flags and options. It specifies which configuration files (Standard Library, plugins, default_env.nu, env.nu, default_config.nu, config.nu, login.nu) are loaded or skipped in each scenario based on the flags used (e.g., -l, -c, --config, -n, --no-std-lib). The section also highlights whether the REPL is entered or a specified command/script is executed.
