解决了：
以下是使用管道输入的函数/脚本的最简单示例.每个行为与管道到“echo”cmdlet的行为相同.
作为功能：
Function Echo-Pipe {
Begin {
# Executes once before first item in pipeline is processed
}
Process {
# Executes once for each pipeline object
echo $_
}
End {
# Executes once after last pipeline object is processed
}
}
Function Echo-Pipe2 {
foreach ($i in $input) {
$i
}
}
作为脚本：
#Echo-Pipe.ps1
Begin {
# Executes once before first item in pipeline is processed
}
Process {
# Executes once for each pipeline object
echo $_
}
End {
# Executes once after last pipeline object is processed
}
#Echo-Pipe2.ps1
foreach ($i in $input) {
$i
}
例如.
PS > . theFileThatContainsTheFunctions.ps1 # This includes the functions into your session PS > echo "hello world" | Echo-Pipe hello world PS > cat aFileWithThreeTestLines.txt | Echo-Pipe2 The first test line The second test line The third test line
您还可以选择使用高级功能,而不是上面的基本方法：
原文链接：https://www.f2er.com/javaschema/281552.htmlfunction set-something {
param(
[Parameter(ValueFromPipeline=$true)]
$piped
)
# do something with $piped
}
很明显,只有一个参数可以直接绑定到管道输入.但是,您可以将多个参数绑定到管道输入上的不同属性：
function set-something {
param(
[Parameter(ValueFromPipelineByPropertyName=$true)]
$Prop1,[Parameter(ValueFromPipelineByPropertyName=$true)]
$Prop2,)
# do something with $prop1 and $prop2
}
希望这可以帮助您学习另一个shell.
