我如何在mac上缓存git的密码

Question

I am following the instructions at https://help.github.com/articles/set-up-git . But when I get to the step

sudo mv git-credential-osxkeychain \
  "$(dirname $(which git))/git-credential-osxkeychain"
# Move the helper to the path where git is installed
# Password: [enter your password]

I keep getting errors for dirname . dirname is my /User/myname directory. so I try replacing it with /User/myname , then with / , then with . . Each time it throws a complaint such as

-bash: dirname: is a directory
mv: git-credential-osxkeychain: No such file or directory

Or in the case of .

-bash: ????: command not found
mv: git-credential-osxkeychain: No such file or directory

But when I go to my HD I do see the file git-credential-osxkeychain there under path (ie info) /

You need to input the command

sudo mv git-credential-osxkeychain \
    "$(dirname $(which git))/git-credential-osxkeychain"

exactly as it is written; don't replace dirname with a directory name. (The point of this command is to get your shell to do that replacement itself.)

The password you're prompted for is your computer's password—the use of sudo is what's triggering the password prompt here.
