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
#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.
Even when this disclaimer is not here:

I think you don't understand. I was pointing out that the command you specified would print the name '.' and that is all. It won't descend through '.' because you told it to prune all directories not named "logs". That is, I'm trying to point out that it's your *logic* that's flawed. OP was right in his thinking. The correct way to approach the problem is to ignore (prune) the logs dir, and then to do something with the remaining directories. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

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. -- -Chris ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos

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. ___ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
