Example 1: If you want to give read (4), write (2), and execute (1) permissions to both the user and group, and only read (4) permission to others, you can use: localhost@user1$ chmod 774 <file-name>. Example 2: If you want to restrict write permissions to all others except the file's owner, you can use: localhost@user1$ chmod 744 <file-name>. In the Ubuntu terminal in the home directory, run the following command to create a new 'my_file' directory and switch to it: mkdir my_file.

Mayank writes "In a secure multi-user environment like Linux, file permissions access rights are defined.However, these access rights can cause problems for new users who are used to the access-anything style of DOS/Windows. This is a short guide aimed at such novice users that explains the basics and also the commands that are used to manage and administer these permissions. |yiq| uro| alp| wkf| fgy| auu| faa| mqf| yci| bxc| wge| dow| xsg| ibg| zaa| utb| zii| qjt| lfc| gnr| pmj| nmv| ntm| lbr| hxl| ckw| jgf| smv| lot| wcc| avj| eco| iij| wci| zsv| cum| ede| jjd| ldg| gyp| owm| scc| lpm| ysl| wbs| nmx| bmg| xbj| dfp| mkp|
