New03

These functions are new in (R)?ex Version 0.3.

Rex

• rsync interface

  A simple rsync interface is now available. To use it, you need the Perl Module Expect.

  use Rex::Commands::Rsync;
  
  desc "Sync /etc";
  task "etc", "server1", "server2", "server3", sub {
     sync "/filestore/public/etc", "/etc";
  };

  Or, if you want to sync a remote directory to a local one

  task "get-logs", "server", sub {
      sync "/var/log", "/tmp/logs", { download => 1 };
  };

• debug mode

  There is a new command line switch "-d" for debugging.

• Logging

  Now you can define a logging destination.

  Log to a file:

  logging to_file => 'rex.log';

  Log to syslog:

  logging to_syslog => 'local0';

• Run Command from Command-Line

  Example:

  rex -e "run 'hostname'" -H "www01 www02 www03" -u root -p password

  or with serverranges

  rex -e "run 'hostname'" -H "www[01..10]" -u root -p password

  or if you only want to get the hostname from every 3rd server

  rex -e "run 'hostname'" -H "www[01..10/3]" -u root -p password

• Server-Ranges

  Now you can define serverranges like "www[1..10]" or "www[01..10]".

  task "uname", "www[1..10]", sub {
     run "uname -a";
  };

  or

  group "webserver" => "www[01..15]", "web[1..3]";
  task "uname", group => "webserver", sub {
     run "uname -a";
  };

• Call Tasks from other tasks

  Now you can call tasks from other tasks.

  Example:

  task "hostname", "server1", "server2", sub {
     run "hostname";
     do_task "uname";
  };
  
  task "uname", "server1", "server2", sub {
     run "uname -a";
  };

rexify

• A simple command to create a Rexfile skeleton.

  rexify ProjectName

  This will create a Rexfile and file lib/Rex/ProjectName.pm where you can define your Tasks.
