how to import env

[Lee]

Hello,

In perl, how to run a bash script to set up environment variables in
current process? For example, suppose I have a bash script
setup_env.sh to set up some environ variables. In a shell script, I
can always say,

.. setup_env.sh
....other work follows.

in perl, how can I do that? %ENV is too complicated. I assume there
must be quite simple solution here.

Thanks!

Lee

Well, %ENV is the mechanism provided for changing environment variable
values in the process in which Perl is running. I'm not aware there is
any other, so the meaning of your statement "%ENV is too complicated"
escapes me. More complicated that some wished-for simpler (by some
definition of simpler) but non-existent mechanism? What is so
complicated about:

$ENV{environment_variable_name}='environment_variable_value';

anyway? If you want to place it in a separate Perl program and call it,
check out:

perldoc -f do
