在PowerShell错误消息中使用touch命令创建新文件 [英] Creating new file with touch command in PowerShell error message
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,然后键入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?我需要一直使用Git Bash吗?
Why is it not working? Will I have to use Git Bash all the time?
推荐答案
如果在PowerShell中需要命令touch
,则可以定义一个执行正确的事情的函数:
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
}
}
将函数放入您的配置文件,以便在您启动PowerShell时可用.
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
具有强制性参数-Type
,并且您不能在PowerShell别名定义中包括参数.
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.
