How do I import environment settings into my Perl program?

Question

I have a script whose content simply exports a variable in linux.

export LD_LIBRARY_PATH=....

I want to run this script in my Perl script so whoever is running my Perl script will have their LD_LIBRARY_PATH set. Can i just do this in the beginning of my Perl script:

#!/usr/bin/perl -w

system(". /myfolder1/myfolder2/myScript.sh");

Answer 1

#!/bin/sh
. /myfolder1/myfolder2/myScript.sh
exec perl -wxS "$0" "$@"
#!/usr/bin/perl -w
# .. the rest of your script as normal

When you run this, it will first be executed by /bin/sh, which is capable of loading myScript.sh into the local environment. sh then execs Perl, which is told to continue from the following line.
