I have a folder in my subdomain which is created through WHM so the owner of that subdomain is not the owner of main domain. I want to change the owner of one of the folders of subdomain to domain owner. I tried this, but when I check with winscp it shows owner as 500.

 chown users:user /home/xyz/somnething/photo/ 

I’ve tried to change from winscp also, but there is no option for winscp, so I’ve logged in as root using putty and ran the command from above, but it doesn’t help and I am unable to upload any file to subdomain from the main domain, as it returns error «permission denied».

$ ls -l /home/xyz/somnething/photo/ total 8 drwxr-xr-x 2 sujit sujit 4096 Feb 21 23:39 ./ drwxr-x--- 5 rohan nobody 4096 Feb 22 02:28 ../ 

I want to give the ownership of rohan to sujit to have rights to upload file from sujit domain to subdomain rohan Update: Now it is changing owner to 500

Use chown to change ownership and chmod to change rights.

use the -R option to apply the rights for all files inside of a directory too.

Note that both these commands just work for directories too. The -R option makes them also change the permissions for all files and directories inside of the directory.

sudo chown -R username:group directory 

will change ownership (both user and group) of all files and directories inside of directory and directory itself.

sudo chown username:group directory 

will only change the permission of the folder directory but will leave the files and folders inside the directory alone.

you need to use sudo to change the ownership from root to yourself.

Note that if you use chown user: file (Note the left-out group), it will use the default group for that user.

Also You can change the group ownership of a file or directory with the command:

chgrp group_name file/directory_name 

You must be a member of the group to which you are changing ownership to.

You can find group of file as follows

# ls -l file -rw-r--r-- 1 root family 0 2012-05-22 20:03 file # chown sujit:friends file 

User 500 is just a normal user. Typically user 500 was the first user on the system, recent changes (to /etc/login.defs) has altered the minimum user id to 1000 in many distributions, so typically 1000 is now the first (non root) user.

What you may be seeing is a system which has been upgraded from the old state to the new state and still has some processes knocking about on uid 500. You can likely change it by first checking if your distro should indeed now use 1000, and if so alter the login.defs file yourself, the renumber the user account in /etc/passwd and chown/chgrp all their files, usually in /home/, then reboot.

But in answer to your question, no, you should not really be worried about this in all likelihood. It’ll be showing as «500» instead of a username because o user in /etc/passwd has a uid set of 500, that’s all.

Also you can show your current numbers using id i’m willing to bet it comes back as 1000 for you.

How to Change the Owner of Directory in Linux

Under a Linux file system, we have files, folders, and directories. A folder only contains files and a directory contains both folders and files. Each of these files, folders, and directories are associated with an owner, a group, and permission access rights.

This article guide will walk us through determining and changing the ownership of a directory on a Linux system.

Why Change Directory Ownership in Linux?

• You might need an already created directory to only be accessible by a specific user.
• In an organizational setting, when a user quits, changing the directory ownership to folders and data prevents/revokes the initial access privileges the user had.
• When working with scripts like Python or Bash scripts, their execution might need access to directory data and therefore a directory owner must be identified for these scripts to execute successfully.
• During file transfers between different Linux systems on a network, directory ownership needs to be changed with respect to the users involved.

Problem Statement

For this article, we need a preexisting directory with already set directory ownership. Consider the following directory whose ownership is revealed via the following commands.

$ ls -l LinuxShellTips_Files $ ls -l -d LinuxShellTips_Files

The first column reveals the associated permission access rights, the second column reveals the associated owner, and the third column shows the associated group.

In the above case, we have owner dnyce and group dnyce for LinuxShellTips_Files directory, its sub-directories and files.

Changing Directory Ownership in Linux

To meet this objective, we are going to borrow the effectiveness of the Linux chown command-line utility, which is part of the GNU Coreutils package and is primarily used to change the owner and group name of a targeted file.

The chown command reference syntax is as follows:

$ chown [OPTION]. [OWNER][:[GROUP]] FILE.

As per the above chown command syntax, we first need to identify the new owner and group name that will inherit the to-be vacated directory ownership.

To list all the active owners in your Linux system run the command:

To list all the active groups in your Linux system, run the command:

Alternatively, you could create a new user you wish to have the new ownership of the vacated directory.

$ sudo adduser tutor $ sudo adduser tutor sudo

Changing Directory Ownership

To change the ownership of our sample directory from owner dnyce to owner tutor, we will implement the following chown command.

$ sudo chown tutor LinuxShellTips_Files

Confirm that the directory ownership has changed:

$ ls -l -d LinuxShellTips_Files

To change both the user and group ownership of the directory to tutor, execute the command:

$ sudo chown tutor:tutor LinuxShellTips_Files

Changing Directory and Sub-directories Ownership

The sub-directories in the above parent directory have different ownership and to change their ownership to be the same as the parent directory, run:

$ sudo chown -R tutor:tutor LinuxShellTips_Files

Confirm if the ownership changes took place:

$ ls -l -d LinuxShellTips_Files $ ls -l LinuxShellTips_Files

We can now change the ownership of any directory on a Linux as a sudoer/root user.

How do I change the owner of a directory in Linux?

All files and directories that exist on your Linux system have an owner, a group, and permission access rights that are granted to the file owners, its group members, or others. The chown command permits a Linux user to change any directory or file’s ownership. In this post, we will demonstrate the usage of the chown command for changing ownership through practical examples. But firstly, you should understand why you would want to change the ownership of any directory or file?

Here is the list of few scenarios in which you want to do this:

• For example, you want an already created directory or file to be accessible to a particular user.
• When a user leaves an organization, all of his data comes under the responsibility of another employee. Therefore, you want to change the ownership of the new team member.
• Changing directory or file ownership is also necessary when you are writing a script that has to be used by only a specific person.
• Transferring files between different Linux systems also requires changes in files and directories ownership.

Now let’s check out the syntax of the chown command.

chown command syntax

Utilize the “User” for the username or replace it using the user ID, also known as UID. Add the group name in the “Group” part of the GID (group ID). At the end of the chown command, add files or directories for which you want to change the ownership.

Changing the owner of a directory

We have created a separate user named “utest” and a group “ugroup” for demonstrating the examples. To change the ownership of any directory, utilize the chown command with the username and path of the directory.

Now, write out the “ls” command and check if your directory ownership is updated or not.

Changing the ownership of all sub-directories

Utilize the “-R” option of the chown command for changing the owners of all the files or folders present in a directory.

List out the directory content to view the results.

Changing the owner of a file

First of all, list out the file content to know about its ownership.

After that, specify the name of the user who you want to be the new owner of this file. In our case, we have chosen “utest” to avail the ownership of “samplefile.txt.”

Again, verify the updated ownership changes.

You can also use the “User ID” or “UID” of any user for this purpose. For that, retrieve the user ID of the new user by utilizing the “id” command with the “-u” option.

Add the User ID instead of the username to make the ownership changes.

Changing the owners of multiple files

Specify the file names at the end of the chown command to change the ownership of multiple files at once.

Write out the below-given command to confirm the changes.

Changing the owner of directory and file at once

Follow the below-given method for changing the owners of the file and directory instantly.

This command will make “utest” the new owner of the “test directory” and the “samplefile.txt.”

Changing the owner using wildcards

Wildcards are used to select a specific file group according to the given pattern. The chown command will then change the owner of the files after retrieving them from the wildcard execution.

Conclusion

For data security concerns, you may want to specify the ownership of files and directories. In Linux, we use the chown command-line utility for changing the ownership of directories or files. You can also utilize this command for changing directories and multiple file ownership at once. In this post, all of these statements are justified by providing practical examples.
