在cygwin上使用shell脚本时参数过多错误

Question

I am trying to run a script on cygwin prompt.

ssh-keygen -t rsa $email
eval $(ssh-agent -s)
ssh-add ~/.ssh/id_rsa
mkdir -p /proj/env
ln -s /usr/bin/proj/env/bin

and running it as email="john.warnet" sh script1.sh.

But it is showing error as

  Too many arguments.

I tried running the script by writing the command on prompt instead of copying.But couldnt find the solution.

如果需要将电子邮件地址作为ssh-keygen的参数传递，则可以按以下方式运行它

ssh-keygen -t rsa  -C $1
