如果＆符命令失败，如何自动停止Powershell。示例：＆$ cmd＃现在失败

Question

我正在尝试编写一个Powershell工具控制脚本，该脚本使用＆运算符调用其他“ .EXE”程序。示例：

$cmd = ".\buffalo_wing.exe"

& $cmd "--really_hot" "--extra_spicy"

# ok now my command has failed by returning non-zero value...
#  but powershell keeps on going like the energizer bunny..

我尝试设置：

$ErrorActionPreference="Stop"

但无济于事。

Answer 1

$cmd = ".\buffalo_wing.exe"

& $cmd "--really_hot" "-o wing.log"
if ($? -eq $false) {
    write-host -background DarkBlue -foreground Red "<Error Exit>"
    exit 1 
}
