I use the cygwin's bash. My default prompt is $. How do I change the prompt as current directory with my user name? default $ I want $/home/user:myname:

You need to set the environment variable PS1 to "$\w:\u: ". You can do this temporarily by writing "export PS1='$\w:\u: '" in the shell and hitting return. Cygwin should have a bash.bashrc file somewhere or a user local ~/.bashrc where you can replace the PS1 setting more permanently.

Thank you,Null and Void!
