default path in Mac OS X

Actually it's for bash setups.

Depending on the type of working environment, in Mac, there are two different ways you need to complete.

1) work on only Terminal:

~/.profile -- personalize personal initialization such as classpath. Within this file you have

PATH=$PATH:...:...

export PATH

Ps. :... is additional path you put into PATH

~/.bashrc -- personalize personal bash option such as defining alias ls='ls -G'

2) work by using GUI too:

In this case, you need to set up normal path in .profile or .bashrc and also in

/.MacOSX/environment.plist

2.1 create .MacOSX folder

$mkdir .MacOSX

$cd .MacOSX/

2.2 create 'environment.plist' file

$touch environment.plist

$open environment.plist

A window of this file will pop up to you

Then, specify 'PATH' as Key and the value of PATH which is already defined in .profile into Value column.
