RE: setting unix command through perl script

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"

Irfan





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