# This file allows you to alter the configuration of the Asterisk # init.d script. Normally you should leave the file as-is. # # RUNASTERISK: If set to anything other that 'yes', the asterisk init.d script # will not run. The default is 'yes'. #RUNASTERISK=no # # # AST_REALTIME: if set to anything other than "no", asterisk will run in # real-time priority (pass '-p' to asterisk). un-rem the # following line to disable asterisk from running in real-time # priority #AST_REALTIME=no # # PARAMS: extra parameters to pass to asterisk: generate cores in # case of crash, and be more verbose. -F guarantees that Asterisk # will still run daemonized. # # Instead of adding switches here, consider editing # /etc/asterisk/asterisk.conf #PARAMS="-F -g -vvv" # # # RUNASTSAFE: run safe_asterisk rather than asterisk (will auto-restart upon # crash). This is generally less tested and has some known issues # with properly starting and stopping Asterisk. #RUNASTSAFE=yes # # ASTSAFE_CONSOLE: whether you want safe_asterisk to spawn a console for Asterisk. #ASTSAFE_CONSOLE=yes # # ASTSAFE_TTY: tty for Asterisk to run on (only for safe_asterisk) #ASTSAFE_TTY=9 # # MAXFILES: Set this to the number of open file handles the Asterisk # process can have. Useful if you get "Too many open files" error. #MAXFILES=8192 # # AST_DUMPCORE: if set to anything other than "no", asterisk will be run with # the option -g (to tell it to dump core on crash) and its # working directory will be set to /var/spool/asterisk, as that # directory is writable and hence core files can be written there. # See /etc/init.d/asterisk for some other relevant variables. # # It is recommended that you install asterisk-dbg to be able # to produce meaningful backtraces from the core file. # # By default core files will be written to /tmp (can be # changed by setting AST_DUMPCORE_DIR). Alternatively, see # CORE_PATTERN below. #AST_DUMPCORE=yes # # AST_DUMPCORE_DIR: By default asterisk runs in the directory '/' like any # daemon. Setting this allows you to tell it to tell the # Asterisk daemon to run in a different directory if # AST_DUMPCORE is enabled. The default is # /var/spool/asterisk. That is a good choice because it # is writable (thus enabling the actual writing of the # core file) but relatively immune to symlink attacks # (because not world-writable like /tmp/). # Note, however, that if CORE_PATTERN is an absolute # path, it will override AST_DUMPCORE_DIR. # # CORE_PATTERN: If you use AST_DUMPCORE above, this is optionally set to a # pattern of the core file. The default is not to touch the # core_pattern settings, which is generally a good idea as # it affects every core file generated on your system. # # However if you just enable generation of core files and run # asterisk as a daemon it will fail to write core files. # # Alternatively you can set this independently elsewhere. # See http://lxr.linux.no/source/Documentation/sysctl/kernel.txt # Here is what Asterisk's ast_grab_core # script would expect: #CORE_PATTERN='core.%p' # But you might prefer something like: #CORE_PATTERN='core.%e.%t'

|
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 |
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
|
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 |
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
|
Комментарии, не относящиеся непосредственно ни к какой из команд, добавляются точно таким же способом, только вместо симолов #^ или #v нужно использовать символы #=
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.
LiLaLo (L3) расшифровывается как Live Lab Log.
Программа разработана для повышения эффективности обучения Unix/Linux-системам.
