You must type in "whereis bashrc" in SSH and it will tell you exactly where the file is on your server. You will then have two options...
1. If your control panel (WHM/cpanel, etc.) allows you to access and edit files you can locate it and edit it there. If you can't, there are tools/addons to allow you to do this.
2. Use a good ssh/putty tool like
MobaXterm. It also has options to view your files on the server as well as choosing a default editor to edit and save them.
