Update cli_printActionPreamble.sh:
- Do not limit file verification to just regular files. Remember
that documentation entries have dependent entries and they are
stored inside a directory. In order to remove the directory that
stores dependent documentation entries such directory should be
passed to the list of entries we want to remove and if that list
doesn't accept directories when passed through
cli_printActionPreamble then the elimination flow would stop
without perform the elimination action at all.
- Use default file verifcation (`-a') instead.
