以下是一些常用的 Linux 命令，这些命令可以帮助你在 Linux 系统中进行文件管理、系统监控、网络配置等操作。

### 文件和目录管理
1. **`ls`** — 列出目录内容
   - `ls`：列出当前目录的文件和子目录。
   - `ls -l`：列出详细信息（权限、所有者、大小、修改日期等）。
   - `ls -a`：显示所有文件（包括隐藏文件）。

2. **`cd`** — 改变目录
   - `cd /path/to/directory`：切换到指定目录。

    $Destination = "$home\links\$title.lnk"

    $sourcepath =$url


    $WshShell = New-Object -comObject WScript.Shell

    $Shortcut = $WshShell.CreateShortcut("$Destination")

    $Shortcut.TargetPath = $sourcepath

#获取环境变量
$pspath=[System.Environment]::GetEnvironmentVariable('psModulepath','machine')
#添加环境变量
$pspath+=";$home\modules"
#设置环境变量
[System.Environment]::SetEnvironmentVariable('psmodulepath',$pspath,'machine')
#系统环境变量和用户环境变量的区别

系统环境变量： 'machine'
当前用户环境变量：'User'

        [Parameter(Mandatory, ParameterSetName = 'PathAll', Position = 0)]

windowS常见encoding:有 cp936,UTF-8
确保你和来源字体编码相同
powershell一般使用的是utf-8,确保你来源和终端encoding相同即可

如果来源JavaScript 可以用
iconv-lite 模组进行encoding 转码
实例:
cp936:utf-8
const { exec } = require('node:child_process');
const path = require('node:path');

1.via bat:
const { exec, spawn } = require('node:child_process');

exec('my.bat', (err, stdout, stderr) => {
  if (err) {
    console.error(err);
    return;
  }
  console.log(stdout);
});

1.The ValidateSet attribute specifies a set of valid values for a parameter or variable and enables tab completion. PowerShell generates an error if a parameter or variable value doesn't match a value in the set. In the following example, the value of the Fruit parameter can only be Apple, Banana, or Pear.


 [ValidateSet('Apple', 'Banana', 'Pear')]


2.You can use a Class to dynamically generate the values for ValidateSet at runtime. In the following example, the valid values for the variable $Sound are generated via a Class named SoundNames that checks three filesystem paths for available sound files:
Class SoundNames : System.Management.Automation.IValidateSetValuesGenerator {
    [string[]] GetValidValues() {
        $SoundPaths = '/System/Library/Sounds/',

[Parameter(
   Position = 0,
   ValueFromPipeline = true,
   ValueFromPipelineByPropertyName = true)]
[ValidateNotNullOrEmpty]
public string[] Name
{
   get { return this.processNames; }
   set { this.processNames = value; }
}
