Why must I source .bashrc every time I open terminal for aliases to work?

问题

Git was working fine. I have created an alias in Git but the issue is when I tried to reopen the terminal, then I need to run . ~/.bashrc every time in the terminal.

What is the best way I don't need to provide source every time when I reopen the terminal?

What I did? I am trying to add source of the .bashrc file in this file but it is a read-only file. I am not able to add the source of the .bashrc file in this profile.

open /etc/profile

Added the permission to write in the profile as well, still not able to link the source file.

sudo chmod u+w /etc/profile

Profile:

# System-wide .profile for sh(1)

if [ -x /usr/libexec/path_helper ]; then
   eval `/usr/libexec/path_helper -s`
fi

if [ "${BASH-no}" != "no" ]; then
   [ -r /etc/bashrc ] && . /etc/bashrc
fi

It looks like your terminal emulator is launching bash as a login shell.

If that's the case, it will read /etc/profile for configuration as well as 1 of the following files, if they exist (listed in order of importance) :

~/.bash_profile
~/.bash_login
~/.profile

It will thus ignore your .bashrc file. A correct fix for your situation would be to either configure your terminal emulator to run bash interactively and non-login, or add [ -f "$HOME/.bashrc" ] && source "$HOME/.bashrc" to your ~/.bash_profile

Here is a link to the documentation about which files are loaded depending of the type of shell you are running

As per @Aserre's answer i have followed this step to solve this issue

A typical install of OS won't create a .bash_profile for you. When you want to run functions from your command line, this is a must-have.

Start up Terminal
Type cd ~/ to go to your home folder
Type touch .bash_profile to create your new file.
Edit .bash_profile with your favorite editor (or you can just type open -e .bash_profile to open it in TextEdit.
[ -f "$HOME/.bashrc" ] && source "$HOME/.bashrc" Save it and close it

Restart the terminal, It should work
