I want to execute "export CCASE_NO_FILE_HEADER=yes" command in Perl script. If I run this command on bash prompt then it is executing properly but if I try to execute this command through perl script then it is not executing at all
How should I achieve this . is there any another way. Please help.

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.
