Tidy up dir recursively

[Christian Linden]

Hi,

how do I rm -rf on a dir:

 files:

          comp_exists::

            "/path/to/my/dir/."

              delete => tidy,

              depth_search => recurse("inf"),

                classes => if_ok("removed");

This results in:  Dangerous or ambiguous promise - '/path/to/my/dir/.' specifies recursive deletion but has no file selection criteria

There are utility bundles rm_rf(name), and rm_rf_depth(name, depth) in the
standard library.

bundle agent rm_rf(name)
# @brief recursively remove `name` to any depth, including base
# @depends rm_rf_depth
# @param name the file or directory name
#
# This bundle will remove `name` to any depth, including `name` itself.
#
# **Example:**
#
# ```cf3
# methods:
#     "bye" usebundle => rm_rf("/var/tmp/oldstuff");
# ```
{
  methods:
      "rm" usebundle => rm_rf_depth($(name),"inf");

}

bundle agent rm_rf_depth(name,depth)
# @brief recursively remove `name` to depth `depth`, including base
# @depends recurse_with_base tidy all
# @param name the file or directory name
# @param depth how far to descend
#
# This bundle will remove `name` to depth `depth`, including `name` itself.
#
# **Example:**
#
# ```cf3
# methods:
#     "bye" usebundle => rm_rf_depth("/var/tmp/oldstuff", "100");
# ```
{
  classes:
      "isdir" expression => isdir($(name));
  files:
    isdir::
      "$(name)"
      file_select => all,
      depth_search => recurse_with_base($(depth)),
      delete => tidy;

      "$(name)/."
        delete => tidy;

    !isdir::
      "$(name)" delete => tidy;
}

Use a file_select attribute.

next prob:

classes:

          "comp_exists" expression => fileexists("/path/to/my/dir");

The class is set no matters if dir is a dir or a file =(

classes:
          "comp_exists" expression => fileexists("/path/to/my/file");
          "comp_exists" expression => fileexists("/path/to/my/dir/.");

or
          "comp_exists" expression => fileexists("/path/to/my/file");
          "comp_exists" expression => isdir("/path/to/my/dir");

[Christian Linden]

isdir is worth a try.

> "comp_exists" expression => fileexists("/path/to/my/file“);

>> this sets class if file is a dir as well.

Thanks, Neil, I’m out for 2day.

Please use
https://docs.cfengine.com/docs/master/reference-standard-library-common.html#rm_rf
or
https://docs.cfengine.com/docs/master/reference-standard-library-common.html#rm_rf_depth
in the standard library. Both have examples of how to use them. IMHO
that's significantly easier than learning all the attributes and bodies
you need for such a simple task.

cool, Ted, thank you =)
