Powershell 工作流实战(1)

假如说我们要写个powershell脚本，功能是找出禁用的账号，找出过期的账号，找出密码永不过期的账号，则可以运行以下三条语句即可。

Search-ADAccount -AccountDisabled | Select-Object -Property DistinguishedName | Export-Csv -Path c:\workflow\01-DisabledAccounts.csv -NoTypeInformation
Search-ADAccount -AccountExpired | Select-Object -Property DistinguishedName | Export-Csv -Path c:\workflow\02-ExpiredAccounts.csv -NoTypeInformation
Search-ADAccount -PasswordNeverExpires | Select-Object -Property DistinguishedName | Export-Csv -Path c:\workflow\03-PsswdNeverExpireAccounts.csv -NoTypeInformation

如果改成workflow脚本，则可以写成如下：

workflow get-ADReport {

parallel {
Search-ADAccount -AccountDisabled | Select-Object -Property DistinguishedName | Export-Csv -Path c:\workflow\01-DisabledAccounts.csv -NoTypeInformation

Search-ADAccount -AccountExpired | Select-Object -Property DistinguishedName | Export-Csv -Path c:\workflow\02-ExpiredAccounts.csv -NoTypeInformation

Search-ADAccount -PasswordNeverExpires | Select-Object -Property DistinguishedName | Export-Csv -Path c:\workflow\03-PsswdNeverExpireAccounts.csv -NoTypeInformation

}

}

还可以改成这样的

workflow get-ADReport {

workflow get-disabled {
Search-ADAccount -AccountDisabled | Select-Object -Property DistinguishedName | Export-Csv -Path c:\workflow\01-DisabledAccounts.csv -NoTypeInformation
}
workflow get-expired {
Search-ADAccount -AccountExpired | Select-Object -Property DistinguishedName | Export-Csv -Path c:\workflow\02-ExpiredAccounts.csv -NoTypeInformation
}
workflow get-passwordneverexpire {
Search-ADAccount -PasswordNeverExpires | Select-Object -Property DistinguishedName | Export-Csv -Path c:\workflow\03-PsswdNeverExpireAccounts.csv -NoTypeInformation
}
parallel {
get-disabled
get-expired
get-passwordneverexpire
}

}

再或者，将它们单独放置，改成以下模式也是可以的

workflow get-disabled {
Search-ADAccount -AccountDisabled | Select-Object -Property DistinguishedName | Export-Csv -Path c:\workflow\01-DisabledAccounts.csv -NoTypeInformation
}
workflow get-expired {
Search-ADAccount -AccountExpired | Select-Object -Property DistinguishedName | Export-Csv -Path c:\workflow\02-ExpiredAccounts.csv -NoTypeInformation
}
workflow get-passwordneverexpire {
Search-ADAccount -PasswordNeverExpires | Select-Object -Property DistinguishedName | Export-Csv -Path c:\workflow\03-PsswdNeverExpireAccounts.csv -NoTypeInformation
}

workflow get-ADReport {

parallel {
get-disabled
get-expired
get-passwordneverexpire
}

}
