You should be able to do the same as your were doing in Linux in macOS.
As an example, if using
alias vscode="open -a 'Visual Studio Code'"
.bash_profile file will let you just type
vscode in Terminal to open Visual Studio Code.
Note: If you are running macOS Catalina, or later, and have not installed a more recent version of
bash and are using the default
zsh shell, then put
aliases in your
~/.zprofile, or the appropriate file for the shell you are running.
Also, you might want to read Visual Studio Code on macOS to add the
code executable to your
path, depending on your shell.
