i changed PROMPT_COMMAND to this as you said, it fixes what i mentioned earlier, but produces more problem, like when i type one character and then use BACKSPACE to delete it, the entire promt is gone, and again bring me to the begining of the line, also when i use ^R to search for history command, the prompt is destroyed too...
I do something similar, but I don't change PS1 in the prompt command. My prompt does end up on two lines, but when I'm in a long path at least the command edit area stays large. PS1='\[\e[1;32m\]\u\[\e[1;33m\]@\h\[\e[0m\] \$ ' PROMPT_COMMAND='echo -e "\e[1;36m$(date "+%a %d%b%y %H:%M:%S") \e[1;33m${PWD/${HOME}/~}\e[0m"
