Neither Terminal or iTerm on Mac is white/black color by default, which looks tedious. What if different entries shown in different colors?
Fortunately, we can do this just by writing a configuration file, then the terminal console or iTerm can look like this:

So how can we do this?
It’s very simple, just create a file named ~/.bash_profile, and fill it with the following content:

1
2
3
4
5
6
7
8
9
10
11

#enables colorin the terminal bash shell export
export CLICOLOR=1

#sets up thecolor scheme for list export
export LSCOLORS=gxfxcxdxbxegedabagacad

#sets up theprompt color (currently a green similar to linux terminal)
export PS1='\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;36m\]\w\[\033[00m\]\$ '

#enables colorfor iTerm
export TERM=xterm-color

If you are not satisfied with that color, you can change the value of LSCOLORS.

The value of LSCOLORS describes what color to use for which attribute when colors are enabled with CLICOLOR. This string is a concatenation of pairs of the format fb, where f is the foreground color and b is the background color.

The color designators are as follows:

• a black
• b red
• c green
• d brown
• e blue
• f magenta
• g cyan
• h light grey
• A bold black, usually shows up as dark grey
• B bold red
• C bold green
• D bold brown, usually shows up as yellow
• E bold blue
• F bold magenta
• G bold cyan
• H bold light grey; looks like bright white
• x default foreground or background

The order of the attributes are as follows:

1. directory
2. symbolic link
3. socket
4. pipe
5. executable
6. block special
7. character special
8. executable with setuid bit set
9. executable with setgid bit set
10. directory writable to others, with sticky bit
11. directory writable to others, without sticky bit
