我有一个包含如下文本的文件：
{名称：“乔恩”，孩子：[{i：1，n：“tyrell”}，{i：2，n：“angela”}，{i：3，n：“elliot”}]
我想要实现的是用“：i”删除每个字符串，所以在这种情况下它看起来像这样
{名称：“乔恩”，孩子：[{n：“tyrell”}，{n：“angela”}，{n：“elliot”}]
因此，如果有一个“i:”，它应该删除所有内容（包括 i:)，直到逗号“，”
我怎么能做到这样的事情？
当我编写如下 bash 脚本时：
#!/bin/bash
nc localhost [pseudoport]
echo "test"
它连接到服务器但不发送文本“test”。
它适用于
#!/bin/bash
echo "test" | nc localhost [pseudoport]
这里的问题是在收到某些内容后连接退出。
如何发送多条消息，在我的情况下是固定前导码，后跟可变数据？
我正在尝试在 Ubuntu 16.04 上安装 cuda，所以我首先要做的是检查预安装操作并验证我的系统是否满足依赖项。
我删除了与 nvidia 相关的所有内容，下载了 .deb 文件并安装了它。
之后，我将以下内容添加到 PATH 变量中：
export PATH=/usr/local/cuda-9.1/bin${PATH:+:${PATH}}
现在我尝试了这个命令：
cat /proc/driver/nvidia/version
但在 proc/driver/ 目录中没有 nvidia 文件夹...
如果它尝试make一个示例，我会收到错误，因为没有库或什至已经安装了所有东西。
我现在正在尝试 3 天：/
当我输入以下内容时：
apt-cache policy libdns162
我收到这个输出：
