- user-manual: Running Asciidoctor Securely: Set the safe mode in the CLI
////

When Asciidoctor is invoked via the CLI, the safe mode is set to `UNSAFE` by default.
You can change the safe level by executing one of the following commands in the CLI.

`-S`, `--safe-mode=SAFE_MODE`::
Sets the safe mode level of the document according to the assigned level (`UNSAFE`, `SAFE`, `SERVER`, `SECURE`).

`--safe`, `asciidoctor-safe`::
Sets the safe mode level to `SAFE`.
Provided for compatibility with the python AsciiDoc `safe` command.

////
-B, --base-dir=DIR
Base directory containing the document and resources. Defaults to the directory containing the source file, or the working directory if the source is read from a stream. Can be used as a way to chroot the execution of the program.
