Guessing environment variables set origin

[Yguaratã C. Cavalcanti]

Hi guys,

is there any way to guess if a environment variable was set by system of if
it was defined by the configuration files?

I imagined that i could to this by parsing some files such as /etc/profile
or ~/profile, for example. However it would require a complete bash script
parser, i guess.

Any ideas?

Thank you!
