The .bashrc file is in your home directory.
So from command line do:
cd
ls -a
This will show all the hidden files in your home directory. “cd” will get you home and ls -a will “list all”.
In general when you see ~/ the tilda slash refers to your home directory. So ~/.bashrc is your home directory with the .bashrc file.
And the standard path to homebrew is in /usr/local/ so if you:
cd /usr/local
ls | grep -i homebrew
you should see the homebrew directory (/usr/local/homebrew). Source
Yes sometimes you may have to create this file and the typical format of a .bashrc file is:
# .bashrc
# User specific aliases and functions
. .alias
alias ducks=’du -cks * | sort -rn | head -15′
# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
PATH=$PATH:/home/username/bin:/usr/local/homebrew
export PATH
If you create your own .bashrc file make sure that the following line is in your ~/.bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
I would think you should add it to ~/.bash_profile instead of .bashrc, (creating .bash_profile if it doesn’t exist.) Then you don’t have to add the extra step of checking for ~/.bashrc in your .bash_profile
Are you comfortable working and editing in a terminal? Just in case, ~/ means your home directory, so if you open a new terminal window that is where you will be “located”. And the dot at the front makes the file invisible to normal ls command, unless you put -a or specify the file name.
