Just use alias  Here s a basic example     Define alias in shell alias rmi  rm -i     Define alias in config file alias rmi  rm -i     This is equivalent to entering the following function  function rmi     rm -i  argv end    Then  to save it across terminal sessions  funcsave rmi   This last command creates the file    config fish functions rmi fish   Interested people might like to find out more about fish aliases in the official manual

To properly load functions from    config fish functions  You may set only ONE function inside file and name file the same as function name   add  fish extension    This way changing file contents reload functions in opened terminals  note some delay may occur  1-5s   That way if you edit either by commandline  function name  function content  end   then  funcsave name   you have user defined functions in console and custom made in the same order

I found the prior answers and comments to be needlessly incomplete and or confusing  The minimum that I needed to do was   Create    config fish config fish  This file can optionally be a softlink  Add to it the line alias myalias echo foo bar  Restart fish  To confirm the definition  try type myalias  Try the alias

If you add an abbr instead of an alias you ll get better auto-complete  In fish abbr more closely matches the behavior of a bash alias   abbr -a gco git checkout   Will -add a new abbreviation gco that expands to git checkout   Here s a video demo of the resulting auto-complete features
