Question

我正在编写一个简单的PowerShell脚本来检查文件的两个可能位置。检查数组后，如果值返回True，则会添加一个注册表项。但是，如果值为false，则返回表明未安装的消息。

# Verify if directory exists
$reg6432path = "HKLM:\SOFTWARE\WOW6432Node\xabx\123"
$reg32path = "HKLM:\SOFTWARE\xabx\123"

$CheckLoc64 = "${env:ProgramFiles(x86)}\xabx\123.abc"
$CheckLoc32 = "${env:ProgramFiles}\xabx\123.abc"
$CheckLocArray = $CheckLoc32, $CheckLoc64

$PathExists = Test-Path $CheckLocArray
IF ($PathExists -eq $True) {
write-host "xabx is installed"
write-host "Writing registry values"
new-itemProperty -Force -Path $reg6432path -Name "LogonSettingsPath" -Value $CheckLoc64
}
ELSE { new-itemProperty -Force -Path $reg32path -Name "LogonSettingsPath" -Value $CheckLoc32 }

IF ($PathExists -eq $False) {
write-host "xabx Not Installed" }

这有效，但我很好奇是否有任何改进可以帮助清理它。

如果使用test-path检查数组，并且1为true而另一个为false，则返回true。你需要个性化测试。我会做这样的事情。

# Verify if directory exists
$reg6432path = "HKLM:\SOFTWARE\WOW6432Node\xabx\123"
$reg32path = "HKLM:\SOFTWARE\xabx\123"

$CheckLoc64 = "${env:ProgramFiles(x86)}\xabx\123.abc"
$CheckLoc32 = "${env:ProgramFiles}\xabx\123.abc"

$Path64 = Test-Path $CheckLoc64
$Path32 = Test-Path $CheckLoc32
IF ($Path64 -eq $True) {
    write-host "xabx is installed"
    write-host "Writing registry values"
    new-itemProperty -Force -Path $reg6432path -Name "LogonSettingsPath" -Value $CheckLoc64
}
elseif ($Path32 -eq $True) {
    new-itemProperty -Force -Path $reg32path -Name "LogonSettingsPath" -Value $CheckLoc32 
} 
else {
    write-host "xabx Not Installed"     
}

或者你可以在if语句中编入索引。 [1]告诉if语句查看变量$ PathExists中的第二个对象。

# Verify if directory exists
$reg6432path = "HKLM:\SOFTWARE\WOW6432Node\xabx\123"
$reg32path = "HKLM:\SOFTWARE\xabx\123"

$CheckLoc64 = "${env:ProgramFiles(x86)}\xabx\123.abc"
$CheckLoc32 = "${env:ProgramFiles}\xabx\123.abc"
$CheckLocArray = $CheckLoc32, $CheckLoc64

$PathExists = Test-Path $CheckLocArray
IF ($PathExists[1] -eq $True) {
    write-host "xabx is installed"
    write-host "Writing registry values"
    new-itemProperty -Force -Path $reg6432path -Name "LogonSettingsPath" -Value $CheckLoc64
}
ELSE { new-itemProperty -Force -Path $reg32path -Name "LogonSettingsPath" -Value $CheckLoc32 }

IF ($PathExists -eq $False) {
    write-host "xabx Not Installed" 
}

数组上的测试路径并返回值
