Agreed that the parent process in which perl was invoked will not be changed
by the perl script.

What is the overall objective?

Try to do everything you need to do inside the perl script, or everything
you need to do outside the perl script.

HTH,
Ken Wolcott

i think this is not possible.

if you start a new process (shell) it gets the environment of its parent
process. but if you manipulate the environment in a child the parent will
not notice this..

for example

$ bash
$ export FOO=BAR
$ echo $FOO
BAR
$ exit
$ echo $FOO

Hi All,



I need to execute the "export CCASE_NO_FILE_HEADER=yes" command
through Perl script.



What I did is qx(export CCASE_NO_FILE_HEADER=yes); but still the
value for CCASE_NO_FILE_HEADER is not getting set to "yes"



Regards,

Irfan





With Perl you can get and set environment variables through using %ENV
ie. $ENV{FOO} = 'bar'
