如何在PowerShell复制脚本中正确复制多个字符串
如何在PowerShell复制脚本中正确复制多个字符串
提问于 2013-09-04 22:29:30
我正在使用this answer中的PowerShell脚本执行文件复制。当我想要使用过滤器包含多种文件类型时，问题就出现了。
Get-ChildItem $originalPath -filter "*.htm" | `
foreach{ $targetFile = $htmPath + $_.FullName.SubString($originalPath.Length); `
New-Item -ItemType File -Path $targetFile -Force; `
Copy-Item $_.FullName -destination $targetFile }就像做梦一样。但是，当我想要使用过滤器包含多种文件类型时，问题就出现了。
Get-ChildItem $originalPath `
-filter "*.gif","*.jpg","*.xls*","*.doc*","*.pdf*","*.wav*",".ppt*") | `
foreach{ $targetFile = $htmPath + $_.FullName.SubString($originalPath.Length); `
New-Item -ItemType File -Path $targetFile -Force; `
Copy-Item $_.FullName -destination $targetFile }出现以下错误：
Get-ChildItem : Cannot convert 'System.Object[]' to the type 'System.String' required by parameter 'Filter'. Specified method is not supported.
At F:\data\foo\CGM.ps1:121 char:36
+ Get-ChildItem $originalPath -filter <<<< "*.gif","*.jpg","*.xls*","*.doc*","*.pdf*","*.wav*",".ppt*" | `
+ CategoryInfo : InvalidArgument: (:) [Get-ChildItem], ParameterBindingException
+ FullyQualifiedErrorId : CannotConvertArgument,Microsoft.PowerShell.Commands.GetChildItemCommand我有各种不同的括号迭代，没有括号，-filter，-include，将包含定义为变量(例如，$fileFilter)，每次都会得到上面的错误，并且总是指向-filter后面的任何内容。
有趣的例外是当我编写-filter "*.gif,*.jpg,*.xls*,*.doc*,*.pdf*,*.wav*,*.ppt*"代码时。没有错误，但是我没有得到任何结果，也没有任何东西返回到控制台。我怀疑我无意中用这句话编写了一个不显式的and？
那么，我做错了什么，我如何才能纠正它呢？

像这样的东西应该可以工作(它对我是有效的)。想要使用-Filter而不是-Include的原因是，与-Filter相比，include的性能受到了巨大的影响。
下面只是循环显示每个文件类型和在单独文件中指定的多个服务器/工作站。
##
## This script will pull from a list of workstations in a text file and search for the specified string
## Change the file path below to where your list of target workstations reside
## Change the file path below to where your list of filetypes reside
$filetypes = gc 'pathToListOffiletypes.txt'
$servers = gc 'pathToListOfWorkstations.txt'
##Set the scope of the variable so it has visibility
set-variable -Name searchString -Scope 0
$searchString = 'whatYouAreSearchingFor'
foreach ($server in $servers)
{
foreach ($filetype in $filetypes)
{
## below creates the search path. This could be further improved to exclude the windows directory
$serverString = "\\"+$server+"\c$\Program Files"
## Display the server being queried
write-host “Server:” $server "searching for " $filetype in $serverString
Get-ChildItem -Path $serverString -Recurse -Filter $filetype |
#-Include "*.xml","*.ps1","*.cnf","*.odf","*.conf","*.bat","*.cfg","*.ini","*.config","*.info","*.nfo","*.txt" |
Select-String -pattern $searchstring | group path | select name | out-file f:\DataCentre\String_Results.txt
$os = gwmi win32_operatingsystem -computer $server
$sp = $os | % {$_.servicepackmajorversion}
$a = $os | % {$_.caption}
## Below will list again the server name as well as its OS and SP
## Because the script may not be monitored, this helps confirm the machine has been successfully scanned
write-host $server “has completed its " $filetype "scan:” “|” “OS:” $a “SP:” “|” $sp
}
}
