Simple Perl variables are called scalars. Examples of scalar values are

   $number      = 123;
   $string      = "String";
   $file_handle = open "<filename";
   $null_value  = undef;
 $instance = MyClass-&gt;new;

Rsync over SSH - (40MB/s over 1GB NICs)

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

  • a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
  • H: preserves hard-links
  • A: preserves ACLs
