Answer Posted / basha
this is called copy on write concept
===================================
when ever an environment variable is modified for the
first time either by the parent process or by the child
process a copy of the variable is given to the child
process. the process which modifies the value will see the
modified value. the other process will see the value
obefore modification.
export statement makes a variable as environment
variable ,visible to child
