Even no output in the buffer. I recommend to suppress the escape sequences in your shell prompt, see the Tramp manual for hints how to do this. > PS: what's meaning of regex: "[^#$\n]*%s\r?$"? It's part of the `format' clause to determine the shell prompt; %s is replaced by the value of `tramp-end-of-output'. In your case, this variable should be "#$ ". Later on, once the connection has been established, `tramp-end-of-output' is a random string like "///e90c02f62ec0d7a2f6da0b67a20f8264#$". > Jacky Wang Best regards, Michael.
