Справка

Для того чтобы использовать LiLaLo, не нужно знать ничего особенного: всё происходит само собой. Однако, чтобы ведение и последующее использование журналов было как можно более эффективным, желательно иметь в виду следующее:

В журнал автоматически попадают все команды, данные в любом терминале системы.
Для того чтобы убедиться, что журнал на текущем терминале ведётся, и команды записываются, дайте команду w. В поле WHAT, соответствующем текущему терминалу, должна быть указана программа script.
Команды, при наборе которых были допущены синтаксические ошибки, выводятся перечёркнутым текстом:
$ l s-l

bash: l: command not found
Если код завершения команды равен нулю, команда была выполнена без ошибок. Команды, код завершения которых отличен от нуля, выделяются цветом.
$ test 5 -lt 4
Обратите внимание на то, что код завершения команды может быть отличен от нуля не только в тех случаях, когда команда была выполнена с ошибкой. Многие команды используют код завершения, например, для того чтобы показать результаты проверки

Команды, ход выполнения которых был прерван пользователем, выделяются цветом.

$ find / -name abc

find: /home/devi-orig/.gnome2: Keine Berechtigung find: /home/devi-orig/.gnome2_private: Keine Berechtigung find: /home/devi-orig/.nautilus/metafiles: Keine Berechtigung find: /home/devi-orig/.metacity: Keine Berechtigung find: /home/devi-orig/.inkscape: Keine Berechtigung ^C

Команды, выполненные с привилегиями суперпользователя, выделяются слева красной чертой.
# id

uid=0(root) gid=0(root) Gruppen=0(root)
Изменения, внесённые в текстовый файл с помощью редактора, запоминаются и показываются в журнале в формате ed. Строки, начинающиеся символом "<", удалены, а строки, начинающиеся символом ">" -- добавлены.
$ vi ~/.bashrc

2a3,5 > if [ -f /usr/local/etc/bash_completion ]; then > . /usr/local/etc/bash_completion > fi
Для того чтобы изменить файл в соответствии с показанными в диффшоте изменениями, можно воспользоваться командой patch. Нужно скопировать изменения, запустить программу patch, указав в качестве её аргумента файл, к которому применяются изменения, и всавить скопированный текст:
$ patch ~/.bashrc
В данном случае изменения применяются к файлу ~/.bashrc
Для того чтобы получить краткую справочную информацию о команде, нужно подвести к ней мышь. Во всплывающей подсказке появится краткое описание команды.

Если справочная информация о команде есть, команда выделяется голубым фоном, например: vi. Если справочная информация отсутствует, команда выделяется розовым фоном, например: notepad.exe. Справочная информация может отсутствовать в том случае, если (1) команда введена неверно; (2) если распознавание команды LiLaLo выполнено неверно; (3) если информация о команде неизвестна LiLaLo. Последнее возможно для редких команд.
Большие, в особенности многострочные, всплывающие подсказки лучше всего показываются браузерами KDE Konqueror, Apple Safari и Microsoft Internet Explorer. В браузерах Mozilla и Firefox они отображаются не полностью, а вместо перевода строки выводится специальный символ.
Время ввода команды, показанное в журнале, соответствует времени начала ввода командной строки, которое равно тому моменту, когда на терминале появилось приглашение интерпретатора
Имя терминала, на котором была введена команда, показано в специальном блоке. Этот блок показывается только в том случае, если терминал текущей команды отличается от терминала предыдущей.
Вывод не интересующих вас в настоящий момент элементов журнала, таких как время, имя терминала и других, можно отключить. Для этого нужно воспользоваться формой управления журналом вверху страницы.
Небольшие комментарии к командам можно вставлять прямо из командной строки. Комментарий вводится прямо в командную строку, после символов #^ или #v. Символы ^ и v показывают направление выбора команды, к которой относится комментарий: ^ - к предыдущей, v - к следующей. Например, если в командной строке было введено:
```
$ whoami
```
```
user
```
```
$ #^ Интересно, кто я?
```
в журнале это будет выглядеть так:
```
$ whoami
```
```
user
```
Интересно, кто я?

Если комментарий содержит несколько строк, его можно вставить в журнал следующим образом:

$ whoami

user

$ cat > /dev/null #^ Интересно, кто я?

Программа whoami выводит имя пользователя, под которым 
мы зарегистрировались в системе.
-
Она не может ответить на вопрос о нашем назначении 
в этом мире.

В журнале это будет выглядеть так:

$ whoami

user

Интересно, кто я?

Программа whoami выводит имя пользователя, под которым
мы зарегистрировались в системе.

Она не может ответить на вопрос о нашем назначении
в этом мире.

Для разделения нескольких абзацев между собой используйте символ "-", один в строке.

Комментарии, не относящиеся непосредственно ни к какой из команд, добавляются точно таким же способом, только вместо симолов #^ или #v нужно использовать символы #=

Содержимое файла может быть показано в журнале. Для этого его нужно вывести с помощью программы cat. Если вывод команды отметить симоволами #!, содержимое файла будет показано в журнале в специально отведённой для этого секции.

Для того чтобы вставить скриншот интересующего вас окна в журнал, нужно воспользоваться командой l3shot. После того как команда вызвана, нужно с помощью мыши выбрать окно, которое должно быть в журнале.

Команды в журнале расположены в хронологическом порядке. Если две команды давались одна за другой, но на разных терминалах, в журнале они будут рядом, даже если они не имеют друг к другу никакого отношения.
```
1
    2
3   
    4
```
Группы команд, выполненных на разных терминалах, разделяются специальной линией. Под этой линией в правом углу показано имя терминала, на котором выполнялись команды. Для того чтобы посмотреть команды только одного сенса, нужно щёкнуть по этому названию.

О программе

LiLaLo (L3) расшифровывается как Live Lab Log.
Программа разработана для повышения эффективности обучения Unix/Linux-системам.
