“别名”：术语“-别名”；未被识别为 cmdlet 的名称”错误

Question

我需要在 firebase 中“调试签名证书 SHA-1”指纹。

但在命令行部分

keytool -list -v \
-alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystore   

当我运行此代码时，我收到如下错误：

C:\Users\Win10\Desktop\firebasse> keytool -list -v \
    >> -alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystore
    Illegal option:  \
    keytool -list [OPTION]...
    
    Lists entries in a keystore
    
    Options:

     -keystore <keystore>    keystore name
     -cacerts                access the cacerts keystore
     -storepass <arg>        keystore password

     -protected              password through protected mechanism
    
    Use "keytool -?, -h, or --help" for this help message
    -alias : The term '-alias' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name,
     or if a path was included, verify that the path is correct and try again.

有人可以帮忙解决吗？

您的命令行部分适用于 Unix（或 Linux）shell，其中 \ 是转义字符。在 PowerShell 上，转义字符是 `，所以

keytool -list -v `
-alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystore

应该可以解决问题。您还可以将所有内容放在一行中：

keytool -list -v -alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystore
