Answer / seshadri sethi
The Shell variable which is exported would available to all
the programs outside the Shell also. And the shell variable
which is not exported, would available for that shell or for
the shell program only, in which the variable is declared.
Export LANG=C
will make the variable LANG the global variable, put it into
the global environment. All other processes can use it.
LANG=C
will change the value only in the current script.

Answer / narendrasairam
What that makes the difference is its Access Scope.
An exported variable is available across the scrips unlike
an unexported one which is local to the script.

Answer / tony
By default, Shells will only keep all variables to the Shell in which they run. This is good, since it assumes variables are not needed outside of a given script. In most cases, that is correct. But, if you have a script that you want to use to set Shell variables, it must be exported in some way. Alternative ways to export variables, is to call a script with "source" or just with a dot and a whitespace.
