Shell::GetEnv::Dumper 0.07

Shell::GetEnv::Dumper is a store and retrieve environment.

SYNOPSIS

# write environment to file
perl /path/to/Shell/GetEnv/Dumper.pm file

# read environment from file
use Shell::GetEnv::Dumper;
$envs = Shell::GetEnv::Dumper::read_envs( $filename );

Shell::GetEnv::Dumper is used by Shell::GetEnv to store and retrieve a subprocess's environment. It uses Storable to write and read the %ENV hash from and to disk.
Writing the environment is done from within the subshell by executing this module as a Perl script. The command line may be formed as follows:

# this loads the path to the module in %INC.
use Shell::GetEnv::Dumper;

# this invokes the module directly, using the Perl which was
# used to invoke the parent process. It uses the fact that we
# use()'d Shell::GetEnv::Dumper and Perl stored the absolute path
# to it in %INC;
$cmd = qq{$^X '$INC{'Shell/GetEnv/Dumper.pm'}' $filename};

Retrieving the environment is done using the read_envs() function.

Note that nothing is exportable from this module.
