Greetings to the apple community. I'm a newbie to mac and the terminal and I have no previous exposure to Linux. I have only casually used computers. However I've been wanting to step up my game and understand a few basics. I've installed this package http://maebert.github.io/jrnl/ which is basically to write entries on the terminal. I've done so, and I've been following the tutorial. However, I'm facing difficulty to edit my entries. The documentation says that I need to change the ~/.jrnl_config file. However, when I try to access it I get permission denied.
Harguns-MacBook-Pro-3:~ hargun3045$ ~/.jrnl_config -bash: /Users/hargun3045/.jrnl_config: Permission denied
I have a very vague idea of user read/write permissions and about Root access, however I'm not very clear how I can go to the particular file and change settings.
Can a experienced user guide me?
