function logicaldisk ($computername)
{
Get-WmiObject -Class win32_LogicalDisk -ComputerName $computername -Filter “drivetype=3” |
Sort-Object DeviceID |
Format-Table -Property $computername,DeviceID,
@{label=’FreeSpace(MB)’;expression={$_.freespace/1MB -as [int]}},

}
$server=get-content “c:\servers.txt”
foreach($i in $server)
{
logicaldisk $i
}
# 在server.txt中写了2个服务器名字，一个服务器名字一行。 在运行这个脚本时报下面的错，请问这是什么意思？ 难道logicaldisk $i 不能这么调用？

最大的可能是你的server.txt中可能有空行

replied 6 年 ago 确实是空行问题，但是去掉空行后，又爆出这个错误。如果我直接运行LogicalDisk DCSER01的话，这个函数是可以运行的。

replied 6 年 ago 我使用了for循环，可以了。
function logicaldisk ($computername)
{
Get-WmiObject -Class win32_LogicalDisk -ComputerName $computername -Filter “drivetype=3” |
Sort-Object DeviceID |
Format-Table -Property $computername,DeviceID,
@{label=’FreeSpace(MB)’;expression={$_.freespace/1MB -as [int]}},
@{label=’Size(GB)’;expression={$_.Size/1GB -as [int]}},
@{label=’%Free’;expression={$_.freespace / $_.size * 100 -as [int]}}
}
$server=get-content “c:\servers.txt”
$j=$server.count
for ($i=0;$i -le $j;$i++)
{
logicaldisk $server[$i]
}
但是老出现这个报错，
