devi@31: 	всё происходит само собой.
devi@31: 	Однако, чтобы ведение и последующее использование журналов

devi@31: 	<ul>
devi@31: 	<li><p> 
devi@31: 	В журнал автоматически попадают все команды, данные в любом терминале системы.
devi@31: 	</p></li>
devi@31: 	<li><p>
devi@31: 	Для того чтобы убедиться, что журнал на текущем терминале ведётся, 
devi@31: 	и команды записываются, дайте команду w.
devi@31: 	В поле WHAT, соответствующем текущему терминалу, 
devi@31: 	должна быть указана программа script.
devi@31: 	</p></li>
devi@31: 	<li><p>
devi@31: 	Команды, код завершения которых отличен от нуля, выделяются цветом.

devi@31: 	</p></li>
devi@31: 	<li><p>
devi@31: 	Время ввода команды, показанное в журнале, соответствует времени

devi@31: 	</p></li>
devi@31: 	<li><p>
devi@31: 	Имя терминала, на котором была введена команда, показано в специальном блоке.

devi@31: 	Вывод не интересующих вас в настоящий момент элементов журнала,

devi@31: 	Небольшие комментарии к командам можно вставлять прямо из командной строки.
devi@31: 	Комментарий вводится прямо в командную строку, после символов #^ или #v.
devi@31: 	Символы ^ и v показывают направление выбора команды, к которой относится комментарий:
devi@31: 	^ - к предыдущей, v - к следующей.
devi@31: 	Например, если в командной строке было введено:
devi@31: <pre class='cline'>
devi@31: \$ whoami
devi@31: </pre>
devi@31: <pre class='output'>
devi@31: user
devi@31: </pre>
devi@31: <pre class='cline'>
devi@31: \$ #^ Интересно, кто я?
devi@31: </pre>

devi@31: 	
devi@31: <pre class='cline'>
devi@31: \$ whoami

devi@31: <pre class='output'>

devi@31: <tr> <td> Интересно, кто я?<br/> </td></tr></table> 
devi@31: 	</p></li>
devi@31: 	<li><p>
devi@31: 	Если комментарий содержит несколько строк,
devi@31: 	его можно вставить в журнал следующим образом:

devi@31: </pre>
devi@31: <pre class='output'>
