# better default 'ls'
alias ls='ls -GFh'
# 'ls' man Note:
#  -G: Enable colorized output.  This option is equivalent to defining CLICOLOR in the environment.  (See below.)
#  -F: Display a slash (`/') immediately after each pathname that is a directory, an asterisk (`*') after each that
#      is executable, an at sign (`@') after each symbolic link, an equals sign (`=') after each socket, a percent
#      sign (`%') after each whiteout, and a vertical bar (`|') after each that is a FIFO.
