vim is the commandline text editor vi (improved) and it features syntax highlight and colors. The good thing is, vim is included by default in Mac OS X – the bad thing is, color support is not enabled by default. To enable syntax highlight in vim create a .vimrc file in your home directory:

set term=builtin_ansisyntax
onset background=dark

if you have a color enabled ls installed in your system, this might be useful too:

export LS_COLORS='no=00:fi=00:di=01;33:ln=01;36:pi=40;33:so=01;35:bd=40;33;01:cd=40;33;01:or=40;31;01:ex=01;32:*.tar=01;31:*.tgz=01;31:*.arj=01;31:*.taz=01;31:*.lzh=01;31:*.zip=01;31:*.z=01;31:*.Z=01;31:*.gz=01;31:*.bz2=01;31:*.deb=01;31:*.rpm=01;31:*.jar=01;31:*.jpg=01;35:*.jpeg=01;35:*.gif=01;35:*.bmp=01;35:*.pbm=01;35:*.pgm=01;35:*.ppm=01;35:*.tga=01;35:*.xbm=01;35:*.xpm=01;35:*.tif=01;35:*.tiff=01;35:*.png=01;35:*.mov=01;35:*.mpg=01;35:*.mpeg=01;35:*.avi=01;35:*.fli=01;35:*.gl=01;35:*.dl=01;35:*.xcf=01;35:*.xwd=01;35:*.ogg=01;35:*.mp3=01;35:*.wav=01;35'

di=01;33 colors directories in ls in bold yellow instead of hard-to-read-darkblue on black terminal windows. You can use this line either directly on your commandline or put it in /etc/profile for everyone on your system or just for yourself into ~/.bashrc
