I was maintaining one of my Swift libraries today. This one was written about a year ago when Swift API Guideline hasn’t come out. I used snake_case for variable names in this project for reasons I forgot.
If I want to map command ll to ls -laxo, for example.
For temporary alias, this would work:
$ alias ll='ls -laxo'
To add a permanent alias, we should create .bash_profile file in the user’s home…
