I'm trying to modify this Linux directory
drwxrwx--- 2 root testGrp 4096 dec 17 16:33 test2
I'm writing groups "user" which outputs this:
user : user adm cdrom sudo dip plugdev lpadmin sambashare developer testGrp
I have group permissions rwx for users in the group testGrp, somehow I cannot read from the directory or create files.
What am I doing wrong?

i am currently trying to get wordpress running on Ubuntu Server 18.04 with apache. I managed to get everything to work, but for some reason i am not able to use ls -l properly anymore on the wordpress directories, in which i played around with permissions. The out-of-the-box permissions didn't allow me to update my themes from the wordpress webinterface.
I can't find a solution to this problem, because the permissions are clearly stating, that i have at least read permission.
Problem: ls -l shows question marks and sais permission denied.
Infos: permissions are rwx for owner www-data, rw for group www-data and r for other. Output of groups includes www-data, so the user should be in the www-data group.
Outputs:
$ ls -l /usr/share/wordpress/
ls: cannot access '/usr/share/wordpress/readme.html': Permission denied
...
ls: cannot access '/usr/share/wordpress/wp-comments-post.php': Permission denied

P.S.: Any extra tips for wordpress security are useful.
Thanks
edit forgot the permissions of the directory, still confusing.

set execute bit permissions for group you belong to.
In Linux, I am the owner of a file, then I tried to change owner to another account, failed. Operation not permitted. Do you know why ? I am the user 'BBB'. Thanks
-bash-4.1$ ls -al
drwxrwxrwx 2 AAA games 4096 Nov 23 14:39 .
drwxr-xr-x 3 AAA games 4096 Nov 23 14:36 ..
-rw-r--r-- 1 BBB esmgroup 16798 Nov 23 14:38 XXX-1.0-SNAPSHOT.jar
-bash-4.1$ chown AAA:games ./*.jar
chown: changing ownership of `./XXX-1.0-SNAPSHOT.jar': Operation not permitted
Only root can change the owner on the file. That's final.
You can do that by login to root using su or use sudo before your command.
More information here: https://unix.stackexchange.com/questions/27350/why-cant-a-normal-user-chown-a-file
You can change the file's group if you're in more than one group.
You should login to root account to be granted to change ownership to any user
You can type sudo before the command and then login to your root user
I have an application. The processes for the application have cacheusr as user. When I create files in the application I get the following ownership and permission:
aless80> ls -FGlAhpa test.xml
-rwxrw-r-- 1 cacheusr 1.6K Oct 19 16:41 test.xml
My question is: how to make sure the created files have permission 777 by default? I just added aless80 to the cacheusr group, but that does not help.
aless80> groups aless80
aless80 : aless80 adm cdrom sudo dip plugdev staff lpadmin sambashare cacheusr vboxusers
aless80> id aless80
uid=1000(aless80) gid=1000(aless80) groups=1000(aless80),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),50(staff),108(lpadmin),110(sambashare),1001(cacheusr),999(vboxusers)
aless80> groups cacheusr
cacheusr : cacheusr root
aless80> id cacheusr
uid=1001(cacheusr) gid=1001(cacheusr) groups=1001(cacheusr),0(root)
you can control the permissions of newly created files with the umask command:
$ umask u+rwx,g+rwx,o+rwx
$ touch foo; mkdir bar
$ ls -ld foo bar
-rw-rw-rw- 1 user user 0 Oct 20 00:00 foo
drwxrwxrwx 2 user user 1024 Oct 20 00:00 bar

I have a VPS and use it for hosting my sites. The server is nginx with php-fdm.
my site is in the /var/www/sitename/html/ and all the files and folders under the html directory owned by www-data www-data. All files permision is 664 and directories (html folder and sub-directories) has 775 permission. And also my user is member of the www-data group.
I can change every files in this folder, but I can't make new file or new folder here. This need sudo privileges. I can create new file in the sub-directories like /var/www/sitename/html/uploads but not in the /var/www/sitename/html/ while they have the same owner and permission.
The user you are logging in as is not the www-data user or a member of the www-data group.
I set things up on my servers so that the user I log in as owns the files/directories, and a webuser group is the owning group, perms are set to 750/640. You can automagically keep the owning group the same across all files/directories uploaded to/created on the server by making the top level web directory setgid.
drwxr-s--- 4 debbie www-data 4096 Oct 6 2015 /var/www-debbie.example.com
If the webserver needs to write files, create the directory and change the permissions on it
sudo mkdir /var/www-debbie.example.com/writeable
sudo chmod 770 /var/www-debbie.example.com/writeable
If you haven't done the setgid thing, then fix the ownership
sudo chown debbie.www-data /var/www-debbie.example.com/writeable
And there ya go, the web server user can write to it.
drwxrws--- 4 debbie www-data 4096 Oct 6 2015 /var/www-debbie.example.com/writeable
I am a linux newbie and I have a very basic question. I have one machine which is machineA and I have a root access to that machine.
Now I need to create these below two directories and give permissions to app user.
Create ZooKeeper Data directory and give permissions to app : /opt/zookeeper/data
Create ZooKeeper Log directory and give permissions to app : /opt/zookeeper/log
I have already created those directories in /opt folder by logging as root -
root#machineA:/opt# ls -lt
drwxr-xr-x 4 root root 4096 Dec 17 13:46 zookeeper
root#machineA:/opt/zookeeper# ls -lt
drwxr-xr-x 2 root root 4096 Dec 17 13:46 log
drwxr-xr-x 2 root root 4096 Dec 17 13:45 data
Now I am not sure how to give permissions to app user as mentioned above? I believe this is pretty easy question but I am not sure how to do that?
Any thoughts?
Here you go:
chown -R app /opt/zookeeper
This will change owner of the /opt/zookeeper directory and all its subdirectories to app.
Use chown to change the owner of a file (or directory):
chown app log data
