basically a text expansion. I have g=git, so when I type “g push” after I hit space after g, it expands it to git in the terminal as if i just typed out git myself. My history doesnt show “g push” it shows “git push” before I push enter

why use aliases (they exist in fish) when you can use abbreviations and your history isnt determined by whatever you set your aliases up as? If you change an alias, your history does not reflect that. If you use abbreviations, your history is perfectly usable
