到目前为止，我想在 PowerShall 脚本中应用多个filter，如下所示，我只能添加单个filter
Get-Childitem "D:\SourceFolder" -recurse -filter "*kps.jpg" | Copy-Item -Destination "D:\DestFolder"
从上面的查询中，我只能将一个文件 kps.jpg 从SourceFolder复制到DestFolder，我如何给多个名称复制一个文件？

要对多个条件进行过滤，请使用$host="localhost"; // Host name
$username="username"; // Mysql username
$password="password"; // Mysql password
$db_name="name"; // Database name
$tbl_name="scores"; // Table name
// Connect to server and select database.
$conn= new mysqli($host, $username, $password, $db_name);
// Retrieve data from database
$sql="SELECT * FROM scores ORDER BY score DESC LIMIT 10";
$result=$conn->query($sql);
$data = [];
// Start looping rows in mysql database.
while($rows = mysqli_fetch_assoc($result)){
$data[] = $rows;
// close while loop
}
foreach ($data as $row){
echo $row['name'] . "|" . $row['score'] . "|";
}
// close MySQL connection
mysqli_close($conn);
参数而不是.hovercontainer {
width: 500px;
margin: 0 auto;
position: relative;
height: 170px;
}
.hovercontainer p{
position:absolute;
top:50%;
text-align: center;
left:0;
right:0;
margin:0 auto;
z-index:10;
}
.hovercontainer img{
width:90%;
-webkit-transition: all .3s ease-in-out;
-moz-transition: all .3s ease-in-out;
-ms-transition: all .3s ease-in-out;
-o-transition: all .3s ease-in-out;
transition: all .3s ease-in-out;
opacity:0;
position: relative;}
.hovercontainer p:hover ~ img{
opacity:1
}
.hovercontainer p:hover{
opacity:0;
}。
<div class="hovercontainer">

Include仅在您还指定-Filter或路径以Get-Childitem "D:\SourceFolder" -Recurse -Include "*kps.jpg", "*kps.png", "*kps.bmp" |
Copy-Item -Destination "D:\DestFolder"
结尾（如Include ）时有效
-Recurse的工作速度比\*（或Get-Childitem "D:\SourceFolder\*"）参数要快。筛选器比其他参数更有效，因为提供程序在cmdlet获取对象时将其应用。否则，PowerShell会在检索到对象后过滤它们。参见the docs
-Filter的缺点是只能提供一个文件名过滤器，而-Include则允许使用一组通配符过滤器。
