+==name debug
+
+==short-description
+
+Run the specified fshell script under a simple debugger.
+
+==long-description
+
+Before executing each line of the script, commands can be entered. Currently the following commands are supported:
+
+=over 5
+
+=item C<s>
+
+Run the next line of the script.
+
+=item C<x>
+
+Show the next line of the script with its variables expanded.
+
+=back
+
+Unlike the L<source|source> command, environment variables set by the script being debugged are not inherited by the parent fshell instance.
+
+Note, this command is specifically for debugging L<fshell|fshell> scripts. If you were looking for a general-purpose debugger, see L<fdb|fdb>.
+
+==see-also
+
+L<fdb|fdb>, L<source|source>
+
+==argument filename script_file_name
+
+The name of the script file to be debugged.
+
+==argument string script_args optional last
+
+Arguments to be send to the script.
+
+==option bool k keep-going
+
+Keep processing the script even if a previous command has returned an error. Without this option set, an error would cause script processing to abort (and the debug command to exit with the error code) unless either C<&&>, C<||> or C<&|> was used to handle the error.
