MacOS Catalina and Above Apple switched their default shell to zsh  so the config files include    zshenv and    zshrc   This is just like    bashrc  but for zsh   Just edit the file and add what you need  it should be sourced every time you open a new terminal window  nano    zshenv alias py python Then do ctrl x  y  then enter to save  This file seems to be executed no matter what  login  non-login  or script   so seems better than the    zshrc file  High Sierra and earlier The default shell is bash  and you can edit the file    bash profile and add aliases  nano    bash profile alias py python Then ctrl x  y  and enter to save   See this post for more on these configs   It s a little better to set it up with your alias in    bashrc  then source    bashrc from    bash profile   In    bash profile it would then look like  source    bashrc

You can add an alias or a function in your startup script file  Usually this is  bashrc   bash login or  profile file in your home directory    Since these files are hidden you will have to do an ls -a to list them  If you don t have one you can create one     If I remember correctly  when I had bought my Mac  the  bash login file wasn t there  I had to create it for myself so that I could put prompt info  alias  functions  etc  in it    Here are the steps if you would like to create one    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  Type    bash profile to reload  bash profile and update any alias you add

To create a permanent alias shortcut  put it in  bash profile file and point  bashrc file to  bash profile file   Follow these steps  I am creating an alias command called bnode to run babel transpiler on ES6 code    Go to terminal command prompt and type    cd      this will take you to the home directory   Note  even though your programming files may be located on your    D  drive     your     bash    files may be located on your    C  drive      To see the location of the home directory  type    pwd      this will show you the home directory path and where the  bash files are probably located  To see all dot  quot   quot  files in the home directory  type    ls -la      this will show ALL files including hidden dot  quot   quot  files  You will see 2 files      bash profile    and     bashrc    Open  bashrc file in VS Code Editor or your IDE and enter    source    bash profile    in first line  to point  bashrc file to  bash profile  Open  bash profile file in VS Code Editor and enter    alias bnode    node modules  bin babel-node      to create permanent bnode shortcut to execute as bash command  Save and close both files Now open the file you want to execute  index js  and open in terminal command prompt and run file by using command    bnode index js    Now your index js file will execute but before creating bnode alias in  bash profile file you would get the error  quot bash  bnode command not found quot  and it would not recognize and give errors on some ES6 code  Helpful link to learn about dotfiles  https   dotfiles github io   I hope this helps   Good luck

If you put blah   usr bin blah  in your    bashrc then you can use  blah in your login shell as a substitute for typing  usr bin blah

In my  bashrc file the following lines were there by default     Alias definitions    You may want to put all your additions into a separate file like      bash aliases  instead of adding them here directly    See  usr share doc bash-doc examples in the bash-doc package   if   -f    bash aliases    then          bash aliases fi   Hence  in my platform  bash aliases is the file used for aliases by default  and the one I use   I m not an OS X user  but I guess that if you open your  bashrc file  you ll be able to identify what s the file commonly used for aliases in your platform

The config file for scripts and programs is    bashrc and the config file that gets loaded when you use Terminal is    bash login   I think the best way is to just have everything in    bashrc   For your specific question just enter  this will overwrite any existing    bashrc    echo  alias blah    usr bin blah     gt  gt    bashrc   into the Terminal and a    bashrc file will be created with your new alises  After that just edit the file to add new aliases  functions  settings etc
