The term '-alias' is not recognized , while generating SHA1 key for firebase

Question

while generating the SHA1 key for firebase , I was using this command

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

then I got this error

-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.

    + CategoryInfo          : ObjectNotFound: (-alias:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

and someone suggested me this command

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

now I am getting this error

keytool error: java.lang.Exception: Keystore file does not exist: %USERPROFILE%/.android/debug.keystore
