Menu
I am using a Macbook Pro, and I wanted to change it to the current directory and a dollar sign prompt in Terminal. I've already looked at these resources to try and solve this issue.
I tried modifying the ~/.bashrc file and saving it but it did not seem to work.
PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting
### Added by the Heroku Toolbelt
export PATH="/usr/local/heroku/bin:$PATH"
export PS1="\W$ ”
The last line is what I added to change the prompt.

To do that you use the ls (or list) command. Type ls and press the Return key, and you'll see the folders (and/or files) in the current directory.
By default, bash shows just your current directory, not the entire path. To determine the exact location of your current directory within the file system, go to a shell prompt and type the command pwd. This tells you that you are in the user sam's directory, which is in the /home directory.
To print the current working directory, we use the pwd command in the Linux system. pwd (print working directory) – The pwd command is used to display the name of the current working directory in the Linux system using the terminal.
This should be done in .bash_profile, not .bashrc.
nano ~/.bash_profile
Add a line containing this:
export PS1="\W\$ "
.bashrc is ONLY excuted when starting a sub-shell. bash login shell uses the following initialization scripts:
.bash_profile
.bash_login
.profile
You need to escape the dollar sign. Like this:
$ PS1="\W\$ "
~$ cd tmp
/Users/philip/tmp
tmp$
And once you change your .bashrc you either need to logout/back-in or . ~/.bashrc to re source it.
I would humbly recommend not doing this. Having a full path is very useful as 'tmp' directories could be anywhere. Consider using "\w" which does relative path (ie. uses ~ to represent HOME)
