#Linux get file details how to#

Learning how to check and change permissions of Linux files and directories are basic commands all users should master. Instead of type in the name of the group that will be the new owner of the file. To change the group ownership type in the following command: chgrp Instead of type in the name of the user who will be the new owner of the file. To change the file ownership use the chown command: chown Use one of the options outlined in the previous passage. Performing either of these tasks requires you first need to switch to superuser privileges. Changing User File and Group OwnershipĪside from changing file permissions, you may come across a situation that requires changing the user file ownership or even group ownership. Note: If you need a more in-depth guide on how to use Chmod In Linux to change file permissions recursively, read our Chmod Recursive guide. The same permission settings can be defined using the octal format with the command: chmod 644 test.txt 7 – for read, write, and execute permissionĪs you have to define permission for each category (user, group, owner), the command will include three (3) numbers (each representing the summation of privileges).įor instance, let’s look at the test.txt file that we symbolically configured with the chmod u=rw,g=r,o=r test.txtcommand.The privileges are summed up and depicted by one number. Instead of letters, the octal format represents privileges with numbers: This option is faster, as it requires less typing, although it is not as straightforward as the previous method. Note: There is no space between the categories we only use commas to separate them.Īnother way to specify permission is by using the octal/numeric format. Use the following command: chmod u=rw,g=r,o=r test.txt To set permission as in the previously mentioned test.txt to be: To set a file, so it is public for reading, writing, and executing, the command is: chmod u=rwx,g=rwx,o=rwx Type the initial letter for each class, followed by the equal sign (=) and the first letter of the read (r), write (w) and/or execute (x) privileges. To specify permission settings using alphanumerical characters, you’ll need to define accessibility for the user/owner (u), group (g), and others (o).

The command that executes such tasks is the chmod command.

You can also use this command to display details of a file, such as the owner of the file and the permissions assigned to the file. The Linux ls command allows you to view a list of the files and folders in a given directory. “Library” is the biggest folder whose size is 3136, so it appears at the top of our list. As you can see, our files and folders are ordered in descending order of their size. The output of this command has been edited for brevity.
