 There are also several environment variables that Nushell uses for specific purposes:
 
+### `$env.CMD_DURATION_MS`
+
+The amount of time in milliseconds that the previous command took to run.
+
 ### `$env.config`
 
 `$env.config` is the main configuration record used in Nushell. Settings are documented in `config nu --doc`.
 
-### `$env.PATH`
-
-The search path for executing other applications. It is initially inherited from the parent process as a string, but converted to a Nushell `list` at startup for easy access.
+### `$env.CURRENT_FILE`
 
-It is converted back to a string before running a child-process.
+Inside a script, module, or sourced-file, this variable holds the fully-qualified filename. Note that this
+information is also available as a constant through the [`path self`](/commands/docs/path_self.md) command.
 
 ### `$env.ENV_CONVERSIONS`
 
 Allows users to specify how to convert certain environment variables to Nushell types. See [ENV_CONVERSIONS](./configuration.md#env-conversions).
 
+### `$env.FILE_PWD`
+
+Inside a script, module, or sourced-file, this variable holds the fully qualified name of the directory in which
+the file resides. Note that this value is also available as a constant through:

 ### `$env.LAST_EXIT_CODE`
 
 The exit code of the last command, usually used for external commands — Equivalent to `$?` from POSIX. Note that this information is also made available to the `catch` block in a `try` expression for external commands. For instance:
