Different users in the operating system have ownership and permission to ensure that the files are secure and put restrictions on who can modify the contents of the files. In Linux there are different users who use the system: Show
Ownership and Permissions: To protect and secure files and directory in Linux we use permissions to control what a user can do with a file or directory. Linux uses three types of permissions:
Types of file Permissions:
Note: To view the permissions we use: ls -l chown command is used to change the file Owner or group. Whenever you want to change ownership you can use chown command. Syntax: chown [OPTION]… [OWNER][:[GROUP]] FILE… chown [OPTION]… –reference=RFILE FILE… Example: To change owner of the file: chown owner_name file_name In our case we have files as follows: Now if I use file1.txt in my case, to change ownership I will use the following syntax: chown master file1.txt where the master is another user in the system. Assume that if you are user named user1 and you want to change ownership to root (where your current directory is user1). use “sudo” before syntax. sudo chown root file1.txt Options:
chown -c master file1.txt
chown -v master file1.txt
Examples:
chown :group1 file1.txt You can see that the group permissions changed to group1 from root, if you use -v option it will report that. We just need to add a “:” to change group.
chown master:group1 greek1 Here, greek1 is a file.
chown --from=master root greek1
chown --from=:group1 root greek1 Here, the group of greek1 is changed to root.
chown --reference=greek1 greek2
chown master:group greek2 greek3 Which Linux command enables you to change the owner and the group with which a file or folder that it is associated with?The chown command allows you to change the user and/or group ownership of a given file, directory, or symbolic link.
