file::slurp::withinpolicy
File::Slurp::WithinPolicy(3pm) User Contributed Perl Documentation File::Slurp::WithinPolicy(3pm)NAME
File::Slurp::WithinPolicy - Applies filesystem policies to File::Slurp
SYNOPSIS
use File::Slurp::WithinPolicy qw(:all);
my $text = read_file( 'filename' );
my @lines = read_file( 'filename' );
write_file( 'filename', $text );
append_file( 'filename', $more_text );
overwrite_file( 'filename', $text );
my @files = read_dir( '/path/to/dir' );
DESCRIPTION
This provides the File::Slurp interface within a policy defined by File::Policy. By default, File::Policy is a no-op and this behaves
identically to File::Slurp. System administrators may want to override the default File::Policy implementation to enforce a local filesys-
tem policy (see File::Policy).
FUNCTIONS
read_dir
See "read_dir" in File::Slurp
read_file
See "read_file" in File::Slurp
write_file
See "write_file" in File::Slurp
append_file
See "append_file" in File::Slurp
overwrite_file
See "overwrite_file" in File::Slurp
EXPORTS
By default, nothing is exported. The ":all" tag can be used to export everything. Individual methods can also be exported.
