Powershell Echo声明+变量一行

Question

我正在运行一个脚本，我希望它能够打印一个＆＃34;语句+变量+语句＆＃34;最后[成功时]。我尝试过一些东西，但它总是以三条独立的线条而不是一条线条返回。回声＆＃34;＆＃34;之前和之后只是为了让它在打印时更容易阅读，我已经尝试过，我得到了相同的结果。

$filename = "foo.csv"

    echo ""
    echo "The file" $filename "has been processed."
    echo ""

我明白了：

The file
foo.csv
has been processed.

Answer 1

如果你使用双引号，你可以直接在字符串中引用变量，因为它们允许变量扩展，而单引号不允许这样做。

$filename = "foo.csv"
Write-Output "The file $filename has been processed."

-> The file foo.csv has been processed.

另外，echo实际上只是Write-Output的别名，所以我使用了全名。

Answer 2

在powershell中，您可以按如下方式使用Write-Host：

$filename = "foo.csv"
Write-Host 'The file' $filename 'has been processed.'

-> The file foo.csv has been processed.

Answer 3

echo ("The file "+ $filename +" has been processed.")
