Re: Re: simulating bash

That's very interesting. I tried to do something like that, but I couldn't figure out how to get it to only return what variables were added from the script run.

Right. If you wanted to do it all in one script, something like the following would probably be the cleanest (untested): # get the "output" environment from the script into a hash my %envhash = map { chomp; split( /=/, $_, 2 ) } `bash.script`; # now get the "ambient environment" and delete that from the hash: for ( `bash -c env` ) { ( my $var, undef ) = split( /=/ ); delete $envhash{$var}; } [download]	[reply] [d/l]

# get the "output" environment from the script into a hash

my %envhash = map { chomp; split( /=/, $_, 2 ) } `bash.script`;

# now get the "ambient environment" and delete that from the hash:

for ( `bash -c env` ) {
    ( my $var, undef ) = split( /=/ );
    delete $envhash{$var};
}
