## SCRIPT: 02_anyfile_COPY-DIRSonly-NOfiles_rsync-include-exclude-dir1-dir2.sh
##
## PURPOSE: For two selected directories, this utility copies the
##          sub-directory structure of the first directory (not the
##          non-directory files in those sub-directories) to the
##          second directory.
##
## METHOD:  Uses 'zenity' with the '--file-selection' option to prompt
##          the user for the 'FIRST' directory.
##
##          Uses 'zenity' with the '--file-selection' option, AGAIN,
##          to prompt the user for the 'SECOND' directory.
##
##          Runs the command
##              rsync -av --include='*/' --exclude='*' dir1/ dir2/
##          in an 'xterm'.
##
##             Alternatively, we could:
##
##             Put the output of the command
##               rsync -av --include='*/' --exclude='*' dir1/ dir2/
##             into a text file.
##
##             Show the text file in a text-file viewer of the
##             user's choice.
##
## NOTE on 'rsync' parms:
##
##     The '-a' (archive) option of 'rsync' is the short way of
##     specifying the following options:
##
##     -r   recursively transfer files
##     -l   'pick up' symlinks
##     -p   retain the permissions of each file
##     -t   retain the time-stamps of each file
##     -g   preserve the group membership of each file
##
## REFERENCES: man rsync
##             and Google terms like 'rsync include exclude directories'
##    
## HOW TO USE: In Nautilus, select ANY file in ANY directory. Then
##             right-click and choose this Nautilus script to run.
##
##             Note: The current directory may be used to initially position
##                   at least one of the file selection GUIs.

The directories that you selected are

  $DIRNAME2

The sub-directory structure of the first directory will be
copied under the second directory --- BUT none of the
NON-directory files under the first directory will be copied
under the second directory.

In other words, JUST directories will be created --- no
'regular' files.

If you are NOT SURE that you want to do that,
CANCEL now.
