CentOS - Feb 2016 - delete directories with find and exclude other directories

Hi all,

I'm attempting to delete some directories and I want to be able to exclude
a directory called 'logs' from being deleted.

This is my basic find operation (without the exclusion)

# find . -type d  |tail -10
./d20160124-1120-df8mfb/deployments
./d20160124-1120-df8mfb/releases
./d20160131-16993-vazqg5
./d20160131-16993-vazqg5/metadata
./d20160131-16993-vazqg5/deployments
./d20160131-16993-vazqg5/releases
./logs
./d20160203-27735-1tqbjh6
./d20160125-1120-1yccr9p
./d20160131-16993-1yf9lnc

I'm just tailing the output so that you have an idea of what's going on
without taking up the whole page. :)

If I try to exlclude the logs directory with the prune command I get back
no results.

root at ops-manager:/tmp/tmp# find . -type d  -prune -o -name 'logs'
-print
root at ops-manager:/tmp#

What am I doing wrong?

Thanks,
Tim

crude thing I would do is:

find . -type d  | grep -v logs

, but that will also exclude other names containing "logs" it is like:

Semilogs2
logs4me

Thanks.

find . -type d ! -name logs -prune (and -print has been a default for a
long time).

You're not applying the prune command to items named logs, for one. :)

find . -name logs -prune -o -type d -print

find will crawl the directory.  Items named logs will not be examined 
further.  Otherwise, if the item is a directory, its name will be printed.

That will prune all of the directories whose name is not "logs", 
starting with "."

So... not terribly useful.

Since you can't have a file and a directory named "logs" in the
same directory at the same time (that I know of), you could turn on bash's
extended globbing.

$ shopt -s extglob
$ rm -rf !(logs)

That will only preserve the top-level entity named logs, though.  If there's
a "logs" in a subdirectory, it'll get deleted.

crude thing I would do is:

find . -type d  | grep -v logs

, but that will also exclude other names containing "logs" it is like:

Semilogs2
logs4me

<SNIP>

#just skip the local logs dir
find . -type d -not -wholename ./logs
#skip dirs that start with /logs any where in the search
find . -type d -not -wholename \*/logs\*
#skip dirs that have log anywhere in their name, like Valeri's
find . -type d -not -wholename \*logs\*

and to actually get rid of the found _empty_dirs_ that are not logs...
find . -type d -not -wholename \*logs\* -exec rmdir {} \;
note 1: as written would have to be ran multiple times to empty deeper directory
trees.
note 2: just because a logs dir is not shown/passed by the above command, does
not mean that there was not one deep within a tree, so recursive removals might
do more than you want. See recent UEFI thread. :)
note 3: rmdir can be replaced with your favorite destruction command, choose
wisely.
note 4: I recommend when using an rm command, use a specific directory _name_ to
find instead of '.', so there is _less_ chance of using it where you
don't want to.
