To do this, you need to copy the file and transfer it to a different location that is intended for the new owner of the data. Once transferred, the new user can now own the files. The step is relatively easy to follow. As mentioned above, every file in the Unix system has its own assigned group which acts as an owner of the said file.
Moreover, the groups can also give access to the data towards a few users. It is worth noting that you can make a Unix group for the files using the panel found on the Unix Groups page.
Also, you can apply these changes only if you are a member of the group. With this, take note of the following command:. Some people might be confused why Unix does not permit changing the owner of a file when you individually own the actual record yourself. This is because changing the ownership of a data means that some other user will be involved with the file and thus, needs his or her permission.
With this, changing ownership of the file entails the permission of both parties. You can only change ownership of a file if you are the superuser. In other words, the above command gives out a key to your closet, but not to your room or apartment.
This will let others move cd to the scripts directory. Because the parent directories don't have r permissions, users will only be able to look ls within the scripts directory, keeping the rest of your file system private.

Manage file permissions on Unix-like systems On this page: Overview View file permissions Change file permissions Symbolic method Absolute form Common issues when sharing data with other users Get help Overview Unix -like operating systems, such as Linux, running on shared high-performance computers use settings called permissions to determine who can access and modify the files and directories stored in their file systems.
View file permissions To view the permissions for all files in a directory, use the ls command with the -la options. For example, if you enter: ls -lah You should see output similar to the following: -rw-r--r-- 1 user1 group1 62 Jan 15 myfile. The letters rwx represent different permission levels: Permission Files Directories r can read the file can ls the directory w can write the file can modify the directory's contents.
This assumes that everyone already has access to the directory where myfile is located and its parent directories; that is, you must set the directory permissions separately.
Permission Number Read r 4 Write w 2 Execute x 1.

To change the ownership, we will execute command as shown below. After changing the ownership of the file, we will again check again the ownership of files to ensure that ownership is changed or not.
