Markdown 内联代码备份不工作

就目前而言,我只是为了一个快速的解决方案而切换了主题,而且效果很好。这些是我在RHCSA课程上的笔记,所以我现在的目标是尽快把它们放到网上,因为课程中的其他一些学生表示了兴趣,所以我将把我的笔记作为一系列的帖子发布。在某个时候,我将在我使用的原始主题中自定义CSS。您似乎正在使用一个正在重置内联代码标记的标准样式的。因此,您可能需要添加一些额外的CSS来定义代码标记的外观 我是怎么得出这个结论的 首先,我检查了输出的HTML源代码,并确认backticks确实是作为代码标记呈现的。然后我使用浏览器开发工具检查了Chrome上的一个代码元素,我右键单击该元素并从上下文菜单中选择了inspect,这就是我观察到的:
请注意,左侧的代码元素在底部部分被选中,页面上相应的文本在窗口的上半部分高亮显示。但是,更重要的是底部的右栏。注意,我添加的蓝色箭头指向用户代理样式表定义的CSS规则;也就是说,当未设置其他规则时,浏览器定义为默认规则的规则。如您所见,该规则被覆盖,显示为被划掉。这意味着另一条规则被赋予了优先权。如您所见,我添加的红色箭头指向已覆盖默认值的规则,该规则在名为normalize.css的样式表中定义。向下滚动该列,我们还可以找到一些继承自父母的规则等,但这些规则看起来并不相关。然后我单击normalize.css文件名,浏览器打开了该文件。我滚动到顶部,找到了该网站的链接。感谢您的侦探工作,因为它让我困惑了整整24小时。我不知道为什么我没有想到Ghost reviewer会使用相同的CSS作为Ghost主题!我试图做一些其他的定制,我自己的CSS覆盖了其他元素,我不想让它覆盖这个循环。我想我需要更精确地了解级联是如何工作的。顺便问一下,使用normalize.css是否至关重要?当然,我会查找它,或者只是暂时禁用它,看看会发生什么。我想在不同的浏览器上会发生不同的情况,所以这可能只是一个有趣的测试。
## Adding new users
While you can use `vipw` to edit the user configuration files, it is better to run `useradd`.
`vim /etc/default/useradd`
The output should look similar to this:
```
GROUP=100
HOME=/home
INACTIVE=-1
EXPIRE=
SHELL=/bin/bash
SKEL=/etc/skel
CREATE_MAIL_SPOOL=yes
```
### Useradd examples
* `useradd -c "Comment here" sarah -s /bin/bash` sets a comment (-c) and defines the default shell (-s)
* `useradd bob -s /usr/sbin/nologin` sets `nologin` as the users's default shell because many users don't need shell access
* `useradd -m -u 1201 -G ops,dev linda` adds user, adds home directory (-m), adds user to groups _ops_ and _dev_ (-G), assigns _UID 1201+ (-u)
* `useradd` creates a locked account until you run `passwd user`
### The login configuration file
The `/etc/login.defs` file sets the configuration for the for the _Shadow Password Suite._ The following are some of its most significant attributes:
> * `MOTD_FILE`: Defines the file that is used as _message of the day_ file. In this file, you can include messages to be displayed after the user has successfully logged into the server.
> * `ENV_PATH`: Defines the `$PATH` variable, a list of directories that should be searched for executable files after logging in.
> * `PASS_MAX_DAYS`, `PASS_MIN_DAYS`, and `PASS_WARN_AGE`: Define the default password expiration properties when creating new users.
> * `UID_MIN`: The first UID to use when creating new users.
> * `CREATE_HOME`: Indicates whether or not to create a home directory for new users.
> * `USERGROUPS_ENAB`: Set to yes to create a private group for all new users. That means that a new user has a group with the same name as the user as its default group. If set to no, all users are made a member of the group users. [^n]
### System-wide Bash shell startup files
* `/etc/profile` runs system-wide environment variables and startup scripts
* `/etc/bashrc` contains system-wide aliases and functions [^n]
### Bash shell personal startup files
While creating a user, `useradd` copies the `/etc/skel` user environment configuration files to the new user's home directory. The following are the default configuration files:
* `~/.bash_profile` contains personal environment variables and startup scripts
* `~/.bashrc` contains personal aliases and functions
* `~/.bash_logout` contains personal scripts to run on logout[^n]
## Using usermod to modify users
These are a couple common use cases for `usermod`:
* `usermod -g sales mike` adds _mike_ to sales as _primary_ group
* `usermod -aG ops lisa` adds _lisa_ to ops as a *secondary* group
## Managing password properties
Here are some example use cases for `passwd` and `chage`:
* `chage -E 2018-12-31 bob` sets Bob's account to expire on a specific date
* `chage -l linda` lists account aging information
* `passwd -n 30 -x 90 lori -w 3` sets _minimum password age_ of 30 days, a _maximum password age_ of 90 days (-w), and starts _warning_ the user 3-days before the password expires (-w)
## Linux group management
The `useradd` command creates a default _primary group_ with the same name as the user.
When a user creates a file, the group owner will be set to that user's primary group. Users have access to files owned by their secondary groups.
Use the `id` command to list a user's group memberships:
`id linda`
The output should look something like this:
`uid=1002(linda) gid=1003(account) groups=1003(account),1001(sales)`
A common use case for secondary groups is to share documents between departments with a file server.
## Creating groups
To create a new group, you can use the `vigr` command to directly modify the `/etc/group` file or you can run the `groupadd` command.
* `groupadd devs` adds a group called _dev_
* `groupadd -g 404 devproject` adds a group called _devproject_ with _Group ID (GUID) 404_
* `grep devproject /etc/group` to confirm that you successfully added a group
### Modifying group membership
* `usermod -g 1003 frank` changes frank's **primary** group to account, assigning GUID of 1003
* `usermod -aG dev lori` adds account as a _secondary_ group for lori
* `usermod -g sales anouk` changes anouk's _primary_ group to sales
