问题 I'm currently making a shell in C++ and I've been able to output the absolute directory as the prompt with getcwd(), however when the user reaches the home directory I would like to output a tilde instead of the home directory. So for example instead of [bb@bbmachine bb] I would like to output [bb@bbmachine ~] How would I do something like that? 回答1: Read first about globbing, notably glob(7). For the expansion of path starting with tilde ~ consider wordexp(3) and glob(3). For showing a path

The following does work as expected: COPY *.zip /home/user1 Is this a bug in Docker or is there a limitation related to tilde expansion that I'm not aware of? Using Docker 1

Any help? 回答1: The home directory in Windows R is set using the environment variable R_USER Set this using Windows (search from the Start Menu for "environment variable"). Whatever you set this to will become what R uses for ~ . I have mine set to C:\Users\trehman\R
