You want to to copy a directory (and all the files and subdirectories in it), from your Perl program.
You want functionality equivalent to the recursive copying performed by the Unix "cp -R" command, but you don't want to use a system() call to do this.
Use the File::NCopy module to recursively copy a directory and all it's contents.
#!/usr/bin/perl use strict; use warnings; use File::NCopy; my $source_dir = 'aa'; my $target_dir = 'bb'; mkdir($target_dir) or die "Could not mkdir $target_dir: $!"; my $cp = File::NCopy->new(recursive => 1); $cp->copy("$source_dir/*", $target_dir) or die "Could not perform rcopy of $source_dir to $target_dir: $!";
If you're familiar with the Unix copy command
cp, you might be
excused for thinking that you could simply copy the existing source directory
to a brand new target directory as follows:
$cp->copy($source_dir, $target_dir); # This will fail
Instead you have to first create the target directory with the
function, and then supply the source argument with the trailing
in order to get the desired behaviour:
$cp->copy("$source_dir/*", $target_dir) #....
