我正在尝试编写一个 PowerShell 脚本来自动删除我们的 FTP 服务器上的空目录。我无法直接访问目录所在的服务器 - 我只能通过 FTP 访问它们。出于这个原因,我编写了一个 PowerShell 脚本,它使用 WinSCP .NET 程序集来(尝试)删除空目录。但是,我有一个问题,因为服务器上的许多目录在目录名称中都有方括号。
例如,目录名称可能被称为:[a]153432
这些目录有很多,因此我希望编写一个脚本来删除它们。这是因为它们是由使用数字创建所需目录的程序创建的。为了处理这个程序,我创建了一个空目录
/latest/[b]test
我的程序是这样的:
# program to test deletion of directories with square-brackets in the name.
$HOSTNAME="myftpservername"
$USERNAME="myftpusername"
$PASSWORD="myftppassword"
$DLL_LOCATION="C:\Program Files (x86)\WinSCP\WinSCPnet.dll"
$LOCAL_DIRECTORY="C:\testdir\extended\baseroot"
# Load WinSCP .NET assembly
[Reflection.Assembly]::LoadFrom($DLL_LOCATION) | Out-Null
# Session.FileTransferred event handler
try
{
$sessionOptions = New-Object WinSCP.SessionOptions
$sessionOptions.Protocol = [WinSCP.Protocol]::ftp
$sessionOptions.HostName = $HOSTNAME
$sessionOptions.UserName = $USERNAME
$sessionOptions.Password = $PASSWORD
$session = New-Object WinSCP.Session
try
{
# Connect
$session.Open($sessionOptions)
$remoteFileWithUnixPath = "/latest/[b]test"
$removalResult = $session.RemoveFiles($remoteFileWithUnixPath)
if ($removalResult.IsSuccess)
{
Write-Host ("Removal of remote file {0} succeeded" -f $remoteFileWithUnixPath)
}
else
{
Write-Host ("Removal of remote file {0} failed" -f $remoteFileWithUnixPath)
}
}
finally
{
# Disconnect, clean up
$session.Dispose()
}
exit 0
}
catch [Exception]
{
Write-Host $_.Exception.Message
exit 1
}
当我运行它时,它会显示以下消息:
PS C:\Users\dbuddrige\Documents\dps> .\delete-squarebracket-dir.ps1
Removal of remote file /latest/[b]test succeeded
但是,该目录不会被删除。
我还尝试使用分隔符指定目录名称,例如:
$remoteFileWithUnixPath = "/latest/\[b\]test"
但这也失败了(但至少它是这样说的):
PS C:\Users\dbuddrige\Documents\dps> .\delete-squarebracket-dir.ps1
Removal of remote file /latest/\[b\]test failed
但是,如果我将目录名称 [和变量$remoteFileWithUnixPath
] 更改为类似
/latest/foo
然后重新运行程序,它删除目录/latest/foo
就好了。
有没有人知道我需要做什么才能让它工作?

完整的工作代码如下:
# program to test deletion of directories with square-brackets in the name.
$HOSTNAME="myftpservername"
$USERNAME="myftpusername"
$PASSWORD="myftppassword"
$DLL_LOCATION="C:\Program Files (x86)\WinSCP\WinSCPnet.dll"
$LOCAL_DIRECTORY="C:\testdir\extended\baseroot"
# Load WinSCP .NET assembly
[Reflection.Assembly]::LoadFrom($DLL_LOCATION) | Out-Null
# Session.FileTransferred event handler
try
{
$sessionOptions = New-Object WinSCP.SessionOptions
$sessionOptions.Protocol = [WinSCP.Protocol]::ftp
$sessionOptions.HostName = $HOSTNAME
$sessionOptions.UserName = $USERNAME
$sessionOptions.Password = $PASSWORD
$session = New-Object WinSCP.Session
try
{
# Connect
$session.Open($sessionOptions)
$remoteFileWithUnixPath = "/latest/[b]test"
$removalResult =
$session.RemoveFiles($session.EscapeFileMask($remoteFileWithUnixPath))
if ($removalResult.IsSuccess)
{
Write-Host ("Removal of remote file {0} succeeded" -f $remoteFileWithUnixPath)
}
else
{
Write-Host ("Removal of remote file {0} failed" -f $remoteFileWithUnixPath)
}
}
finally
{
# Disconnect, clean up
$session.Dispose()
}
exit 0
}
catch [Exception]
{
Write-Host $_.Exception.Message
exit 1
}
