( #3333=superdoc: print w/replies, xml ) Need Help??
I can always set an environment variable using the built in %ENV on Unix (or you mention 'use Env' on Windows) but the idea was to make use of our existing shell environment (which is built dynamically when our software package is installed) so we can have a single source of environment settings (easier to debug, modify, etc.). We needed these shell environments set outside of the Perl script and we didn't want to duplicate them by having another Perl script to set the environment just for Perl.

The code snippet posted will source this shell environment file prior to exec'ing the Perl script, that way it's available to the Perl code. We don't run these programs by hand, they run from a cron job, and we previously had to write a shell wrapper to perform the same function that the snippet does automatically for us. Plus, now any of our shell debugging tools and utilities are using the exact same environment settings as the actual Perl scripts that run the system. Which was the whole point.

I hope this makes sense.

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
