You need to put bash shell aliases in the ~/.bashrc file file executed by bash for non-login shells. On most modern Linux distros, you may want to put all your bash alias definitions into a separate file like ~/.bash_aliases, instead of adding them in the ~/.bashrc file directly.

Please note that ~/.bash_aliases file only works if the following line presents in the ~/.bashrc file:

if [ -f ~/.bash_aliases ]; then
. ~/.bash_aliases
fi

Edit ~/.bash_aliases or ~/.bashrc with the editor of your choice
Append your bash alias with for example with: alias ll='ls -la'
Save and close the file.
Activate alias by typing: source ~/.bash_aliases
