( #3333=superdoc: print w/replies, xml ) Need Help??
I don't even know if this is possible, but hopefully it is. This script needs to run on Win32 and Win64. I need to run a perl script from a shell and change the environment of the shell.

I tried
system("set VAR=5");
but that has no effect on the parent as I would suspect.

I have also tried using Win32::Process::Info to get the parent PID(hopefully there is an easier way).
use Win32::Process::Info; my $pi = Win32::Process::Info->new (); my %subs = $pi->Subprocesses(); my $ParentPID; foreach(keys %subs) { foreach my $pid(@{$subs{$_}}) { if( $pid == $$ ) { print "Parent PID is $_\n"; $ParentPID = $_; } } } my @info = $pi->GetProcInfo($ParentPID); use Data::Dumper; print Dumper \@info;
but I don't know what to do with the parent PID to chenge the environment.

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.
