Just copy and paste the following into Terminal to give you a good idea of how you can alter the Code to your own liking.
PS1='${U}\[\033[01;34m\]Anything-You-Want\[\033[01;32m\]: \[\033[01;32m\]\w\[\033[01;35m\] $\[\033[00m\] '
Don't worry this command is only temporary, you need to edit the .bashrc file in order for it to be permanent.
Note: Be sure to backup the old file and check that a long paste command stays within it's bounds and works properly If your planning to edit .bashrc
You can copy and paste this one if you like:
./rtmpdump -r
