我将 html 文件内容复制到以下形式的文本文件中：

... course 10> user_1 </a><br /><a class="reviewlink" href="https://www.foo.com/moodle/mod/quiz/review.php?attempt=1491">Review attempt<...
... course 10> user_2 </a><br /><a class="reviewlink" href="https://www.foo.com/moodle/mod/quiz/review.php?attempt=1498">Review attempt<...

从这里使用一些shell命令我可以得到内容：

user_1 "https://www.foo.com/moodle/mod/quiz/review.php?attempt=1491"
user_2 "https://www.foo.com/moodle/mod/quiz/review.php?attempt=1498"

到另一个文本文件。

这里...表示一些大的独特文本。

为用户提供更详细的表格：

我的网站www.domainname.com加载 apache2 'It works' 页面，而不是预期的 moode 主页，该主页位于/var/www/html/moodle. 在moodle目录中有一个索引文件index.php，但默认不使用。如果我去www.domainname.com/moodle网站主页来。配置文件/etc/apache2/sites-available/domainname.conf已启用。如何解决这个问题？

<VirtualHost *:80>
    # The ServerName directive sets the request scheme, hostname and port that
    # the server uses to identify itself. This is used when creating
    # redirection URLs. In the context of virtual hosts, the ServerName
    # specifies what hostname must appear in the request's Host: header to
    # match this virtual host. For the default virtual host (this file) this
    # value is not decisive as it is used as a last resort host regardless.
    # However, you must set it for any further virtual host explicitly.
    ServerName www.domainname.com
    ServerAlias domainname.com

    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html/moodle
    DirectoryIndex "index.php"

    #       AllowOverride All
    # </Directory>  

    # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,

    # It is also possible to configure the loglevel for particular
    # modules, e.g.
    #LogLevel info ssl:warn

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    # For most configuration files from conf-available/, which are
    # enabled or disabled at a global level, it is possible to
    # include a line for only one particular virtual host. For example the
    # following line enables the CGI configuration for this host only
    # after it has been globally disabled with "a2disconf".
    #Include conf-available/serve-cgi-bin.conf
 RewriteEngine on
 RewriteCond %{SERVER_NAME} =www.domainname.com

我在 linux 中运行 matlab。在 matlab 中运行脚本时出现以下错误。这里的 RayMet_012007.ray_paths 是位于自定义目录中的输入。

/bin/bash: line 0: type: RayMet_012007.ray_paths: not found
/bin/bash: line 0: type: RayMet_00.ray_paths: not found
Undefined function or variable 'AD'.

我无法弄清楚问题所在。该脚本正在运行。matlab 也安装在自定义目录中。

我想创建一个文本文件，它将添加我将在终端上运行的每个命令作为文本文件中的新行条目。即，我需要记录我在终端中所做的事情。此外，如果我可以将终端中的输出记录以及终端中的输入记录为文本文件，那就更好了。

每次我忘记一个命令时，我都必须在 Internet 上再次搜索该命令。
我可以像上面那样制作一个文件吗？

我找到了类似的帖子，但这些答案并没有解决我的问题。我需要知道我可以在 ubuntu-gnome 中安装自定义 Shell 主题吗？如果是的话，最好的 custo shell 主题是什么？我在哪里可以得到它？在 gnome-tweak-tool 中，我无法在 shell 主题下选择任何内容。任何解决方案？我已经安装了图标主题。

当我尝试在终端中运行 ubuntu-tweak 时，我得到以下信息：

adwaita@adwaita-HP-2000-Notebook-PC:~$ ubuntu-tweak

Attempt to unlock mutex that was not locked

adwaita@adwaita-HP-2000-Notebook-PC:~$ ubuntu-tweak -d

Desktop:gnome (ubuntu-tweak:84)

Attempt to unlock mutex that was not locked

Aborted

adwaita@adwaita-HP-2000-Notebook-PC:~$

现在要做什么？这是一个错误吗？

我怎样才能列出所有添加到我的系统的 ppa 存储库并将其保存到一个.txt文件中，这样我就不想花时间搜索用于全新安装的 ppa，我只需在我的.txt文件中选择一个 ppa 行并附加命令 sudo add-apt-repository？还有其他方法可以做到这一点，我不想手动提供 gpg 密钥吗？

在 6 个月前完成安装后，我试图/使用 ubuntu live cd 扩展我的分区。为了安装软件，我的根分区需要 9GB 的空间。根分区的大小仅为 24GB。为了找到一个安全的解决方案，我使用了我的虚拟盒操作系统，从 ubuntu 安装磁盘启动并使用 GParted 扩展根分区后，效果非常好。所以我选择冒险使用我的主机 ubuntu 14.04 LTS 版本。在启动到实时 ubuntu 14.04 cd 后，我能够删除一个 ntfs 分区，它位于我/的 ubuntu 分区之上。将我的 24GB 空间调整为 61GB 也没有出现任何错误。但是当我重新启动时，它最终出现了一个 grub 救援菜单。我试图找到解决方案，但没有任何效果。

我也做了这个：

sudo mount /dev/sda7 /mnt
sudo mount -o bind /dev/ /mnt/dev
sudo grub-install --root-directory=/mnt /dev/sda
sudo chroot /mnt /bin/bash

# Now within the chroot

sudo update-grub
exit

# Now outside chroot

这也没有帮助。请帮助。 在此处输入图像描述 在此处输入图像描述 在此处输入图像描述
