Talking rsync: How to use -prune-empty-dirs with the options: "+ */", "+ *.c" AND "- *"?


I was reading the rsync manual file, and on line 3155-3157 I read
Quote:
o The combination of "+ */", "+ *.c", and "- *" would include all
directories and C source files but nothing else (see also the
--prune-empty-dirs option)
This really looks both interesting and practical.

So to try it out I first make a complex directory structure, with some *.c, *.txt and *.json files:
Code:
mkdir -p source/{.cache,.codeblocks,.config,.gconf,.chrome/{"Crash Reports",googleCu.default/{datareporting,healthreport/{crash,freeze,delay},analytics/{yourRecentClicks,yourFinancialPasswords,history/{mortage,purchases,socioEconomicClass,gender,race,ethnicity,sxlPreference,age,location,politicalParty},dir1},extensions},igoogle},.gconf}
touch source/{.cache/rememberUrPrivRights.c,.codeblocks/rememberUrPrivRights.c,.config/rememberUrPrivRights.c,.gconf/rememberUrPrivRights.c,.chrome/{"Crash Reports"/rememberUrPrivRights.c,googleCu.default/rememberUrPrivRights.c,igoogle/rememberUrPrivRights.c},.gconf/rememberUrPrivRights.c}
touch source/{.cache/new.txt,.codeblocks/new.txt,.config/new.txt,.gconf/new.txt,.chrome/{"Crash Reports"/new.txt,googleCu.default/{datareporting/new.txt,healthreport/new.txt,analytics/{yourRecentClicks/new.txt,yourFinancialPasswords/new.txt,history/{mortage/new.txt,purchases/new.txt,socioEconomicClass/new.txt,gender/new.txt,race/new.txt,ethnicity/new.txt,sxlPreference/new.txt,age/new.txt,location/new.txt,politicalParty/new.txt},dir1},extensions},igoogle},.gconf/new.txt}
touch source/{.cache/new.json,.codeblocks/new.json,.config/new.json,.gconf/new.json,.chrome/{"Crash Reports"/new.json,googleCu.default/{datareporting/new.json,healthreport/new.json,analytics/{yourRecentClicks/new.json,yourFinancialPasswords/new.json,history/{mortage/new.json,purchases/new.json,socioEconomicClass/new.json,gender/new.json,race/new.json,ethnicity/new.json,sxlPreference/new.json,age/new.json,location/new.json,politicalParty/new.json},dir1},extensions},igoogle},.gconf/new.json}
Note how above NONE of the folders whose functions are unconstitutional have c files.

So with my source folder's complex directory structure set up, I then try the rsync --prune-empty-dirs command with the three "+ */", "+ *.c", and "- *" combinations:
Code:
$ rsync -Savi -Eu --prune-empty-dirs "+ */" "+ *.c" "- *" source destination
rsync: - *: unknown option
rsync error: syntax or usage error (code 1) at main.c(1572) [client=3.1.0]
I ixquicked(internet search) this issue, and I could\'t find "rsync --prune" tutorials that utilized the +/- options with multiple arguments.

Does anyone have any example of how to use -prune-empty-dirs with the three "+ */", "+ *.c", and "- *" combinations?

Try putting a -f in front of each filter rule, so that rsync knows that that is what they are. Otherwise it sees the '-' and assumes its a normal option.

Code:
rsync -Savi -Eu --prune-empty-dirs -f "+ */" -f "+ *.c" -f "- *" source destination
That way you get the following output.

Thanks a lot for filling me in, man files can sometimes lack examples.
