我想编写一个PowerShell脚本,它接受参数并使用函数。
我试过了:
param
(
$arg
)
Func $arg;
function Func($arg)
{
Write-Output $arg;
}
但我得到了这个:
The term 'Func' 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 func.ps1:6 char:5
+ Func <<<< $arg;
+ CategoryInfo : ObjectNotFound: (Func:String) [], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException
很好,我想。我会试着这样做:
function Func($arg)
{
Write-Output $arg;
}
param
(
$arg
)
Func $arg;
但是,我得到了这个:
The term 'param' 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 C:\Users\akina\Documents\Work\ADDC\func.ps1:7 char:10
+ param <<<<
+ CategoryInfo : ObjectNotFound: (param:String) [], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException
我要求的是可行的吗?或者我在请求中是不合理的?

脚本中的param块必须是第一个非注释代码。之后,您需要在调用它之前定义该函数,例如:
param
(
$arg
)
function Func($arg)
{
$arg
}
Func $arg
在您的示例中不需要写入输出,因为默认行为是将对象输出到输出流。

你只需要确保PARAM是你脚本的第一个字符串。
答案 2 :(得分:-3)
您可以将param标签放在函数中..
这样的事情:
function func($avg)
{
param
(
$avg
)
}
