accessdb输出内容

在linux控制台输入accessdb指令，结果密密麻麻地输出了一大堆。

查看accessdb的帮助，结果帮助内容只有一点点（一页）。大概的意思是说，这个指令以人类可读的格式转储man db数据库的内容。

[root@status ~]# man accessdb

差不多就是系统中每个命令的简单说明。看来比较实用。但是描述的内容是用英文写的，对于母语非英文的我来说，读起来太慢。那么，我们就调用翻译的API，将其顺便翻译成中文来阅读吧。由于机器翻译不太准确，那么我们就来个中英文对照吧。

申请翻译的API

这里，我们使用有道翻译API。

首先，百度搜索“有道翻译API”，找到“http://fanyi.youdao.com/openapi”，打开链接。

有账号的话，登录系统。没账号的话，申请一个再登录系统。

跳转到 https://ai.youdao.com/console/#/service-singleton/text-translation文本翻译。如果没有应用的话，创建一个应用。首次使用它，系统会送100元的时长，有效期1年。

右侧中部，各种代码编写的示例代码，这里我们选择C#，抄下来，修改这三个参数就可以用了。
appKey，appSecret ，来自于创建的应用。

           string q = "待输入的文字";string appKey = "您的应用ID";string appSecret = "您的应用密钥"

代码我修改了一下，将其封装成一个类，可以供接下来调用。

    public class YouDaoFanyiV3{public YouDaoFanyiResult Trans(string query){Dictionary<String, String> dic = new Dictionary<String, String>();string url = "https://openapi.youdao.com/api";string appKey = "14b33f4513380000000";string appSecret = "xfACgC1jAAUx9T9n00000000";string salt = DateTime.Now.Millisecond.ToString();//dic.Add("from", "源语言");//dic.Add("to", "目标语言");dic.Add("signType", "v3");TimeSpan ts = (DateTime.UtcNow - new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc));long millis = (long)ts.TotalMilliseconds;string curtime = Convert.ToString(millis / 1000);dic.Add("curtime", curtime);string signStr = appKey + Truncate(query) + salt + curtime + appSecret; ;
#pragma warning disable SYSLIB0021// 类型或成员已过时string sign = ComputeHash(signStr, new SHA256CryptoServiceProvider());
#pragma warning restore SYSLIB0021// 类型或成员已过时dic.Add("q", System.Web.HttpUtility.UrlEncode(query));dic.Add("appKey", appKey);dic.Add("salt", salt);dic.Add("sign", sign);//dic.Add("vocabId", "您的用户词表ID");var result = Post(url, dic);return JsonSerializer.Deserialize<YouDaoFanyiResult>(result);}private string ComputeHash(string input, HashAlgorithm algorithm){Byte[] inputBytes = Encoding.UTF8.GetBytes(input);Byte[] hashedBytes = algorithm.ComputeHash(inputBytes);return BitConverter.ToString(hashedBytes).Replace("-", "");}private string Post(string url, Dictionary<String, String> dic){string result = "";HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);req.Method = "POST";req.ContentType = "application/x-www-form-urlencoded";StringBuilder builder = new StringBuilder();int i = 0;foreach (var item in dic){if (i > 0)builder.Append("&");builder.AppendFormat("{0}={1}", item.Key, item.Value);i++;}byte[] data = Encoding.UTF8.GetBytes(builder.ToString());req.ContentLength = data.Length;using (Stream reqStream = req.GetRequestStream()){reqStream.Write(data, 0, data.Length);reqStream.Close();}HttpWebResponse resp = (HttpWebResponse)req.GetResponse();Stream stream = resp.GetResponseStream();using (StreamReader reader = new StreamReader(stream, Encoding.UTF8)){result = reader.ReadToEnd();}return result;}private string Truncate(string q){if (q == null){return null;}int len = q.Length;return len <= 20 ? q : (q.Substring(0, 10) + len + q.Substring(len - 10, 10));}}

保存accessdb输出内容

先浏览一下，这个命令输出的man db中命令的个数。1872个命令帮助。

[root@status ~]# accessdb |wc -l
1872

将accessdb输出内容保存到一个文本文件，顺排序一下

[root@status ~]# accessdb | sort > accessdb.txt
[root@status ~]# ll
total 180
-rw-r--r--. 1 root root 155218 Apr 10 20:48 accessdb.txt
-rw-------. 1 root root   1068 Oct 15 18:41 anaconda-ks.cfg
[root@status ~]#

将生成的accessdb.txt文件下载到windows pc机。
打开Visual Studio 2022，创建一个控制台项目，添加上面修改后的类，在Program.cs文件中添加如下代码：

using ConsoleApp10;
using System.Text;var output = new StringBuilder();
YouDaoFanyiV3 youDaoFanyiV3 = new YouDaoFanyiV3();var data = File.ReadAllLines("E:\\accessdb.txt").ToList();
data.Sort(StringComparer.Ordinal);char firstChar = 'z';
foreach (var item in data)
{if (firstChar != item[0]){firstChar = item[0];output.AppendLine("```");output.AppendLine("## 以" + firstChar + "开头的命令");output.AppendLine("```bash");}var lines = item.Split("->");var command = lines[0].Trim();output.AppendLine(command);var descript = "";try{descript = lines[1].Trim().Split("gz")[1].Trim().Trim('\"').Trim();}catch{descript = lines[1].Trim().Trim('\"').Trim(); }if (descript == ""){output.AppendLine();continue;}output.Append("\t");output.AppendLine(descript.Replace("'","’"));output.Append("\t");Console.WriteLine(command);var trans = youDaoFanyiV3.Trans(descript);output.AppendLine(trans.translation[0]);Console.WriteLine("\t" + trans.translation[0]);
}output.AppendLine("```");
File.WriteAllText("E:\\accessdb_ok.txt", output.ToString());

编译运行，执行完毕后，得到accessdb_ok.txt文件。文件内容如下：
