If your .bashrc settings are not applied automatically after login, here are
possible reasons and solutions:

.bashrc Might Not Be Sourced on Login Cause: .bashrc is typically sourced
for non-login shells, while .bash_profile or .profile is sourced for login
shells.

Solution: Add the following line to your .bash_profile (or .profile):

if [ -f ~/.bashrc ]; then
    source ~/.bashrc
fi
This ensures that .bashrc is sourced whenever you log in.

Login Shell Behavior Cause: If you're logging in through a graphical
environment (e.g., GNOME, KDE), it might not start a login shell.

Solution: Configure your terminal emulator to launch as a login shell. For
example:

In GNOME Terminal: Go to Preferences > Profiles > Command and check "Run
command as a login shell".  

Shell Type
Cause: If your default shell is not bash, your .bashrc will not be read.

Solution: Confirm your default shell with:

echo $SHELL
If the result is not /bin/bash, change your shell to bash:

chsh -s /bin/bash
Cause: Errors in .bashrc might prevent it from being sourced.

Solution: Check .bashrc for syntax errors:

bash -n ~/.bashrc
Fix any errors if found.
