I have a directory with full permissions with root as owner. What I want is to be able to remove it as a normal user. However, i am not allowed to do so:
radu#Workstation:/tmp$ ls -l | grep cucu
drwxrwxrwx 2 root root 4096 oct 20 10:28 cucu
radu#Workstation:/tmp$ ls -la cucu
total 52
drwxrwxrwx 2 root root 4096 oct 20 10:28 .
drwxrwxrwt 66 root root 45056 oct 20 10:28 ..
radu#Workstation:/tmp$ rm -r cucu
rm: cannot remove 'cucu': Operation not permitted
What do I not get right?
Removing a directory (or a file) consists in deleting its entry into its containing directory, so to remove cucu you need permissions on its parent; alas access rights are rwxrwxrwt, and the t means removal authorized for owner only, as the owner is root, only root can remove cucu.
Sticky bit is set , so only owner can remove the directory.
This is because only root has the permission to remove directory, as you can see
drwxrwxrwx 2 root root 4096 oct 20 10:28 cucu
From your root, change the Permission of directory using chown. For example-
chown radu cucu

I am in the group root who owns a file and all the directories above. Why do I have no access to this file? CentOS 7
$ ls /etc/systemd/system | grep parts.service

sudo is used to verify that you are the user with which you are logged. you can access root files with your user, but you have to tell your PC that you want to acces files from the root group
I have folder in /media on ubuntu - shared from windows via fstab and cifs-utils. Can I share this folder to other user: "miki" (not root)
root#localhost:/media#
drwxr-xrwx 4 root root 4096 Nov 15 12:21 .
drwxr-xr-x 23 root root 4096 Nov 14 06:34 ..
drwxr-xr-x 2 padm root 0 Nov 15 09:34 Archive
drwxr-xrwx 2 root root 4096 Feb 25 2019 kekik
I have try with:
root#localhost:~# sudo chmod -R 757 /media/Archive/
but get:
chmod: changing permissions of '/media/Archive/': Permission denied
Find a solution:
need to modify /etc/fstab by changing:
//windowsServer/Archive /media/Archive cifs username=wundowsuser,password=somepass,uid=1000,iocharset=iso8859-1,rw,file_mode=0777,dir_mode=0777,vers=1.0 0 0
and change group of folder (must umont it first!)
sudo umount -l /media/Archive
sudo chown miki:miki /media/Archive/
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$ chown AAA:games ./*.jar

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 am very new to linux and am using putty and pscp to move files to a live hosted directory. I would like to rename my recently uploaded dist folder to its actual project name using mv but get a permission denied error. What is the safest and most reasonable way to arrange these files so I can rename them?

lawton#lawtonb:/var/www/html$ mv dist BTC_Sorter
mv: cannot move 'dist' to 'BTC_Sorter': Permission denied
If this is a one-time rename, your best course of action would be to run mv with sudo, like this:
sudo mv dist BTC_Sorter
If, however, you'd like to have permissions for your user or group, you should do some reading about chown (The link belongs to the Arch Linux wiki, but should be useful regardless of your distro).
In your particular case, the directory dist is owned both by the user and the group root, hence why you'd need to use sudo, chown or simply the root account.
You are not the owner of the file, you need execute the command with sudo
sudo mv src dest
I am currently creating an application that requires separate users running duplicate programs. They cannot run under root because of security reasons, so they are initiated by a Java app that I am working on, and I am starting them with runuser -l. However, I cannot cd into a directory, even though it is owned by the user, and the user has 770 permissions in the folder.
Here's what I'm running:
runuser -l lp1 -c 'java \-jar /root/Desktop/workspace/LitePanel/servers/server1/server.jar \-Xms1024M nogui'
And the output of this is:
runuser: warning: cannot change directory to /root/Desktop/workspace/LitePanel/bin/servers/server1/: Permission denied
Here's an ls -all:
drwxr-xr-x. 3 root root 4096 Jan 30 14:03 .
drwxr-xr-x. 7 root root 4096 Jan 30 14:02 ..
drwxrwx---. 2 lp1 lp1 4096 Jan 31 03:07 server1
Inside the directory:
drwxrwx---. 2 lp1 lp1 4096 Jan 31 03:07 .
drwxr-xr-x. 3 root root 4096 Jan 30 14:03 ..
-rwxrwx---. 1 lp1 lp1 9170551 Jan 31 03:07 server.jar
And here's /etc/passwd:
lp1:x:501:501::/root/Desktop/workspace/LitePanel/bin/servers/server1/:/bin/false
Anyone know why this is happening? It looks like the user has the necessary permissions to do this.
You have said that the directory itself has permissions 770 and is owned by the user, but what about its parents? I believe the cd command will need at least read access (and possibly execute) on the parent directories.
