# Making the grid and data for contours

ax.contourf(Y,Z,X, zdir='y', offset=0, cmap=cm.coolwarm)

CSV文件如下所示

$current_pc     = "$env:computername"
$filePath      = "c:\users\Ara\Desktop\parameters.csv"
$machineParams = Import-CSV $filePath
$info          = if($machineParams){$machineParams | where {$_.branch -eq $($current_pc.Substring($current_pc.length - 3,3))}}
             else{write-output "CSV not loaded"}
$info

Start-Process -FilePath "c:\users\Ara\Desktop\setup.msi"  -ArgumentList “/qf”, "DATABASE_ID=$($info.param1)" , "ODBC_DATABASE_NAME=$($info.ODBC_param2)" ,  "ODBC_ENGINE_NAME=$($info.param3)" -wait

我的问题是我应该在脚本中包含哪些逻辑？要运行branch param1 param2 param3 ------ ------ ------ ------ 188 apr101 1.0.0.1 0 101 apr104 1.0.0.1 1，它将获取csv文件中的188旁边的值

Answer 1

我只读取$current_pc

的参数

## Q:\Test\2018\05\29\SO_50590213.ps1
$current_pc     = "$env:computername"
$CurrBranch     = $current_pc.Substring($current_pc.length-3,3)
$filePath       = "c:\users\Ara\Desktop\parameters.csv"
$machineParams  = Import-CSV $filePath | where {$_.branch -eq $CurrBranch}
$info = if($machineParams){
    $machineParams
} else {
    write-output "no params for $CurrBranch"
}
$info

Start-Process -FilePath "c:\users\Ara\Desktop\setup.msi"  `
  -ArgumentList “/qf”, "DATABASE_ID=$($info.param1)", `
  "ODBC_DATABASE_NAME=$($info.ODBC_param2)", `
  "ODBC_ENGINE_NAME=$($info.param3)" -wait

示例输出（此pcs名称以610结尾）

branch param1 param2  param3
------ ------ ------  ------
610    aprxxx 1.0.0.1 1

或文件中没有匹配的分支

no params for 610

Answer 2

您可以使用param块并将默认ID定义为计算机名子字符串。

param (
    $ID = (@($ENV:computername) | ForEach-Object {$_.Substring($_.length - 3,3)})
)
$filePath      = "c:\users\Ara\Desktop\parameters.csv"
$machineParams = Import-CSV $filePath | Where-Object {$_.branch -eq $ID}
$info          = if ($machineParams) {
                    $machineParams
                } else {
                    # Use a throw to error out when invalid csv 
                    throw "no params for $ID"
                }
$info

Start-Process -FilePath "c:\users\Ara\Desktop\setup.msi"  -ArgumentList “/qf”, "DATABASE_ID=$($info.param1)" , "ODBC_DATABASE_NAME=$($info.ODBC_param2)" ,  "ODBC_ENGINE_NAME=$($info.param3)" -wait

然后你可以调用你的脚本，当你定义ID参数时，它将覆盖默认方案，并且在不使用时将使用computername方案。

# Use computername scheme
install.ps1
# Use defined ID
install.ps1 -ID 188
