On top of what Scrutinizer already said,

Code:
source_dir=${source_dir}
target=${target_dir}

are two expensive No-Ops, as the value of source_dir is replaced by the value of source_dir etc. So, the entire file_copy.sh script would reduce to
Code:
cp $source_dir $target_dir

, or, with a sanitized parameter file
Code:
. parameter_file.txt
cp $source_dir $target_dir

MasonX::ProcessDir(3pm) 				User Contributed Perl Documentation				   MasonX::ProcessDir(3pm)

NAME
MasonX::ProcessDir - Process a directory of Mason 2 templates VERSION
version 0.02 SYNOPSIS
use MasonX::ProcessDir; # Generate result files in the same directory as the templates # my $pd = MasonX::ProcessDir->new( dir => '/path/to/dir' ); $pd->process_dir(); # Generate result files in a separate directory # my $pd = MasonX::ProcessDir->new( source_dir => '/path/to/source/dir', dest_dir => '/path/to/dest/dir' ); $pd->process_dir(); DESCRIPTION
Recursively processes a directory of Mason 2 templates, generating a set of result files in the same directory or in a parallel directory. Every file with suffix ".mc" will be processed, and the results placed in a file of the same name without the suffix. ".mi", autobase and dhandler files will be used by Mason when processing the templates but will not generate files themselves. For example, if the source directory contains Base.mc httpd.conf.mc proxy.conf.mc etc/crontab.mc blah.mi somefile.txt and we run my $pd = MasonX::ProcessDir->new( source_dir => '/path/to/source/dir', dest_dir => '/path/to/dest/dir' ); $pd->process_dir(); then afterwards the destination directory will contain files httpd.conf proxy.conf etc/crontab somefile.txt where foo and bar are the results of processing foo.mc and bar.mc through Mason. Base.mc and blah.mi may be used during Mason processing but won't generate result files themselves. This class is a convenience extension of Any::Template::ProcessDir. CONSTRUCTOR
Specifying directory/directories o If you want to generate the result files in the same directory as the templates, just specify dir. my $pd = MasonX::ProcessDir->new( dir => '/path/to/dir', ... ); o If you want to generate the result files in a separate directory from the templates, specify source_dir and dest_dir. my $pd = MasonX::ProcessDir->new( source_dir => '/path/to/source/dir', source_dir => '/path/to/dest/dir', ... ); Mason options mason_options An optional hash of options to the Mason interpreter. For example, the default Mason data directory will be ".mason" under the source directory, but you can override this: mason_options => { data_dir => '/path/to/data/dir' } Options inherited from Any::Template::ProcessDir See Any::Template::ProcessDir for other options, such as dir_create_mode file_create_mode readme_filename SUPPORT AND DOCUMENTATION
