Editing your Bash config file

• In these steps, we are using terminal and nano to open and edit a file called ~./bash_profile
• In steps 2-4, the lines of code are meant to be pasted into nano when editing the ~./bash_profile
• In the other steps, the commands are entered in terminal

The ~./bash_profile or ~./bashrc is a configuration file for the terminal.

First make sure you are running bash instead of zsh by running this command: chsh -s /bin/bash

• Macs: nano ~/.bash_profile

  • This command will open your ~./bash_profile in nano

• Windows: nano ~/.bashrc

  • This command will open your ~./bashrc in nano

In steps 2 and 3 we will paste the following aliases AKA shortcuts in nano that will help us visualize our folder poem structures.

2. export PS1="🍋 \w\n\u$ "

   • This will customize your Bash prompt. Feel free to change the emoji. (skip if you use zshell)
   • Explanation: \w shows your full file path so you'll always know where you are in the terminal, \n creates a new line in your bash prompt. \u shows your computer username, and $ symoolizes the end of a bash prompt.

3. alias oldtree="find . -not -path '*/\.*' -print | sed -e 's;[^/]*/;|;g;s;|; |;g'"

   • (if you have homebrew installed enter brew install tree in another terminal window instead)
   • this will add a command you can use that will tree your poems in a more lo-fi way than the tree command we installed with homebrew

4. alias treefile="find . -not -path '*/\.*' | xargs -I {} bash -c 'f={}; echo \$f | sed -e \"s;[^/]*/;|;g;s;|; |;g\"; if [[ \$f == *.txt ]]; then echo; cat \$f; echo; echo; fi'"

   • this will add a command you can use that will tree out the contents of your text files along with the folder structure.

5. Reboot your terminal

Mac:source ~/.bash_profile Windows: source ~/.bashrc

OR close and reopen terminal : )
