Question

我有以下简短的脚本来获取OU中的计算机和显示器的序列号，这可以正常工作：

svn commit

在尝试获取WMIObject之前，此脚本不会检查计算机是否处于联机状态，因此如果计算机处于脱机状态，则在RPC调用超时之前需要很长时间。

在尝试获取WMIObject之前，我尝试修改脚本以使用Test-Connection cmdlet：

Import-Module ActiveDirectory

$searchbase = "OU=some,OU=organisational,OU=units,DC=somedomain,DC=local"

Write-Host ""
Write-Host "Serial Numbers for Computers and Monitors in" $searchbase
Write-Host "--"
Get-ADComputer -SearchBase $searchbase -Filter '*' | `
Select-Object -Expand Name | %{Write-Host ""; echo $_ ; Get-WMIObject -Class Win32_BIOS -ComputerName $_ | Select-Object -Expand SerialNumber; `
$monitor = gwmi WmiMonitorID -Namespace root\wmi -computername $_; ($monitor.SerialNumberID | foreach {[char]$_}) -join ""};

我确定我在做一些语法上很愚蠢的事情。有人能指出我正确的方向吗？

Answer 1

您不能直接管道到if语句，只能管道到cmdlet。

将ForEach-Object语句放在<{em}里面%块（ForEach-Object是... | Select-Object -Expand Name | ` %{ if (Test-Connection -ComputerName $_ -Quiet) { # Get-WmiObject in here } else { Write-Host ""; Write-Host $_ "is offline"; } }的别名）：

Where-Object

如果您不关心将每台计算机的状态写入主机，您还可以使用?（别名... | Select-Object -Expand Name | ?{ Test-Connection $_ -Quiet } | % { Get-WmiObject -ComputerName $_ }）过滤掉离线计算机：

ldapsearch -H ldaps://172.22.5.52/ -b "OU=XXX" -x -d5 ldap_url_parse_ext(ldaps://172.22.5.52/) ldap_create ldap_url_parse_ext(ldaps://172.22.5.52:636/??base) ldap_sasl_bind ldap_send_initial_request ldap_new_connection 1 1 0 ldap_int_open_connection ldap_connect_to_host: TCP 172.22.5.52:636 ldap_new_socket: 3 ldap_prepare_socket: 3 ldap_connect_to_host: Trying 172.22.5.52:636 ldap_pvt_connect: fd: 3 tm: -1 async: 0 TLS: can't connect: The signature algorithm is not supported.. ldap_err2string ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1)

Answer 2

除了@Mathias R. Jessen的答案之外，你还可以摆脱线条延续的反对。

如果行的结尾推断出该语句需要另一个代码块，则不需要它们。与$args = array( 'post_type' => 'listing', 'post_status' => 'publish', 'post__not_in' => array($post->ID), 'orderby' => 'date', 'order' => 'DESC', 'meta_query' => array( 'relation' => 'AND', array( 'key' => 'featured_calendar', 'value' => 'on', 'compare' => '=' ), array( 'key' => 'theend', 'value' => time(), 'compare' => '>', 'type' => 'NUMERIC' // Not sure if you want a TIME here ), ), 'posts_per_page' => 7 ); $featured = new WP_Query($args);或|或{一样。

工作得很好......
