Gents, you misunderstand the intention of the transformer.
The contents of your "cat passwd" command will not end up in the file -- they
are dumped as the output of any script is not considered interesting.
Printing a file is not a transformation, but an unrelated command.
Commands that are transformations are things like gzip $(this.promiser),
/bin/cp file1 file2, etc. Cfengine does not support use of a shell in these
commands either, as this is potentially dangerous securitywise.
If you want to run arbitrary shell commands, use commands promises? Try this...
bundle agent example
{
files:
"/tmp/aleksey.txt"
create => "true", # Must have this!
transformer => "/bin/cp /etc/passwd /tmp/out";
}
It works, but it is not really what transformer was intended for (gzip etc). I
suspect the tar example did not work due to an error executing (run in
verbose). Perms?
