“猫”不被识别为内部或外部命令

‘cat’ 不被识别为内部或外部命令

‘cat’ is not recognized as an internal or external command

cat当我们在 Windows 上，在 CMD shell 中使用该命令时，出现错误“’cat’ 未被识别为内部或外部命令、可运行的程序或批处理文件” 。

要解决该错误，请使用type命令显示文件的内容。

该type命令是 Unix/Linuxcat命令的 Windows 等价物。

# 👇️ display the contents of a file named my_file.txt
type my_file.txt

# 👇️ display the contents of a lengthy file named my_file.txt, one screen at a time
type my_file.txt | more

type命令

用于显示文本文件的内容。

您可以将命令的输出通过管道传递给more命令，以一次显示一个屏幕的冗长文件的内容。

# 👇️ display the contents of a lengthy file named my_file.txt, one screen at a time
type my_file.txt | more

请注意，您可以在 PowerShell 中使用该cat命令。

要打开 PowerShell：

1. 单击搜索栏并键入“PowerShell”。

2. 单击“Windows PowerShell”应用程序。

直接在 PowerShell 中运行 cat 命令来读取文件的内容。

cat my_file.txt

1. 在窗口中打开文件夹。
2. 在资源管理器中按下Shift并右键单击。

3. 单击“在此处打开 PowerShell 窗口”。
4. 运行cat命令。
