Make sure there is no user with the same name as the numeric UID. If there is, the chown command gives priority to the username, not the UID. List the target file names after the new user to change the ownership for multiple files. Use single spaces between the file names. In the following example, root will be the new owner of files sample2 and sample3.
With chown, you can change a group for a file or directory without changing the owning user. The result is the same as using the chgrp command. To assign a new owner of a file and change its group at the same time, run the chown command in this format:. Therefore, to set linuxuser as the new owner and group2 as the new group of the file sample2 :.
Rather than changing the ownership to a specific user, you can use the owner and a group of a reference file. Add the --reference option to the chown command to copy the settings from one file to another:. Remember to type in the names of the files correctly to avoid the error message:. The chown command --from option lets you verify the current owner and group and then apply changes. The example below shows we first verified the ownership and the group of the file sample3 :.
In this post, all of these statements are justified by providing practical examples. Talha is a contributor at Linux Hint with a vision to bring value and do useful things for the world.

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.
In this post, we will demonstrate the usage of the chown command for changing ownership through practical examples. I had an issue where someone else had run make in my directory, and now owned some files that I could not modify. Here is my workaround which handles files and directories, although it leaves the directories lying around with suffix.

Improve this question. Andrew Andrew Shi I think it's a fair question. Reading that man page wouldn't help. Globbing is not part of chmod. Use chown to change ownership and chmod to change rights. 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. In Linux, all files are associated with an owner and a group and assigned with permission access rights for the file owner, the group members, and others.
Unprivileged regular users who wish to change the group membership of a file that they own may use chgrp. Skip to content Close Menu Home. Popular lifehacks.
