问题描述
我的桌面上有一个使用 PowerShell 创建的目录,现在我正在尝试在其中创建一个文本文件.
I have a directory on my desktop created using PowerShell, and now I'm trying to create a text file within it.
我确实将目录更改为新目录,然后输入了touch textfile.txt
.
I did change directory to the new one, and typed touch textfile.txt
.
这是我收到的错误消息:
This is the error message I get:
touch : The term 'touch' is not recognized as the name of a cmdlet, function,
script file, or operable program. Check the spelling of the name, or if a path was
included, verify that the path is correct and try again.
At line:1 char:1
+ touch file.txt
+ ~~~~~
+ CategoryInfo : ObjectNotFound: (touch:String) [], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException`
为什么它不起作用?我必须一直使用 Git Bash 吗?
Why is it not working? Will I have to use Git Bash all the time?
推荐答案
如果您需要在 PowerShell 中使用 touch
命令,您可以定义一个执行正确操作的函数:
If you need a command touch
in PowerShell you could define a function that does The Right Thing™:
function touch {
Param(
[Parameter(Mandatory=$true)]
[string]$Path
)
if (Test-Path -LiteralPath $Path) {
(Get-Item -Path $Path).LastWriteTime = Get-Date
} else {
New-Item -Type File -Path $Path
}
}
将该功能放入您的个人资料 以便在您启动 PowerShell 时它都可用.
Put the function in your profile so that it's available whenever you launch PowerShell.
将 touch
定义为别名 (New-Alias -Name touch -Value New-Item
) 在这里不起作用,因为 New-Item
有一个强制参数 -Type
,并且您不能在 PowerShell 别名定义中包含参数.
Defining touch
as an alias (New-Alias -Name touch -Value New-Item
) won't work here, because New-Item
has a mandatory parameter -Type
and you can't include parameters in PowerShell alias definitions.
