RE: tempFile & shell component

Sorry Andreas, I did write the solution from the top of my head.

The problem that you have now is that I put the LazyConcat as a child
for BashShellScript and BashShellScript reads the command during its
deploy phase and the child is not ready yet because of Compound
lifecycle.

Here is the right solution, in witch all the three components are
orchestrated in the right order:

#include "org/smartfrog/components.sf"
#include "org/smartfrog/services/utils/concat/components.sf"
#include "org/smartfrog/services/filesystem/components.sf"
#include "org/smartfrog/services/os/runshell/components.sf"
         
sfConfig extends Compound {
 
  testFile extends TempFileWithCleanup {
     dir "/tmp";
     prefix "tempfile.txt";
     text "foo";
  }

  command extends LazyConcat {
       string extends LAZY {
         a "ls ";
         b LAZY testFile:filename;
       }
    }
                                                                      
  testCmd extends BashShellScript {
    processName "test";
    cmd LAZY command:concat;
    logLevel 5; // 5 all errors, -1 none
    printStack  true; //default false;
   }

}

Just one more thing. There is now a better component for shell scripting
and it will replace the old "runShell" component:
#include "org/smartfrog/services/shellscript/components.sf"

The documentation for it is attached.
