我试图使用Powershell中的WinSCP将SSH SSH到Ubuntu计算机中，上传一个shell脚本并运行它。在脚本中，我有set -o errexit来确保它在失败时停止。偶然地，我在运行脚本时忘记使用sudo，所以类似chmod u=rwx,g=,o= some-folder的命令失败了，因为不允许SSH用户这样做。这是预料之中的，我可以看到脚本已按预期终止。
但是从Powershell中，我正在做类似的事情：
$session = New-Object WinSCP.Session
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
Protocol = [WinSCP.Protocol]::Sftp;
HostName = $HostName
UserName = $UserName
SshPrivateKeyPath = $SshPrivateKeyPath
SshHostKeyFingerprint = $SshHostKeyFingerprint
}
$session.Open($sessionOptions)
...
$result = $session.ExecuteCommand("$remoteScriptPath '$argument1' '$argument2'")
# In the scenario above I would expect the Check() to fail.
# Instead it moves on without any visible errors.
$result.Check()
如前所述，Check()并没有失败，所以我尝试调试通过，发现$result看起来像：
[DBG]: PS D:\>> $result
Output : Some command output ...
Some other command output ...
...
ErrorOutput : chmod: changing permissions of 'some-folder': Operation not permitted
ExitCode : 1
Failures : {}
IsSuccess : True
这对我来说是违反直觉的。当IsSuccess 不 0 且 ExitCode 不为空时，ErrorOutput如何为真？是WinSCP中的错误还是我不了解的功能？
更新：根据建议附加了会话日志文件...

答案 0 :(得分：1)
实际上，默认情况下WinSCP不会将退出代码1视为错误。
在WinSCP 5.14.1 beta和更高版本中，您可以使用raw session settings ExitCode1IsError进行更改：
$sessionOptions.AddRawSettings("ExitCode1IsError", "1")
