task "mytask1","192.168.137.3", sub {
   say run "hostname";
 };


run 函数是在哪里呢？


Rex::Commands::Run - 执行远程命令

[root@node01 Rex]# perldoc -l Rex::Commands::Run 
/usr/local/perl/lib/site_perl/5.22.1/Rex/Commands/Run.pm


加入一段:

sub run {
   print "ddad2313\n";
  my $cmd = shift;


[root@node01 Rex]# rex mytask1
