sl

https://web.archive.org/web/20131228142311/http://practicalthought.com/sl/

sl takes the most common use of Unix ls, to display the files in a directory compactly in multiple columns, and makes it substantially more useful.

 

$ cat .bash_functions
# Automatically do an ls after each cd
cd() {
  if [ -n "$1" ]; then
    #builtin cd "$@" && ls --group-directories-first
    builtin cd "$@" && sl
  else
    #builtin cd ~ && ls --group-directories-first
    builtin cd ~ && sl
  fi
}

 

In .bashrc add line
source ~/.bash_functions
