看代码符号$?搞不清楚是什么?

 

看代码.

$share = Get-WmiObject -Class Win32_Share -ComputerName $Server.name -Credential $credentials -Filter "Description='Default share'"if($?){   "command succeeded"   $share | Foreach-Object {...}}else{   "command failed"}

 

找到定义如下:

Contains the execution status of the last operation. It contains TRUE if the last operation succeeded and FALSE if it failed.
