I'll also explain some the popular terms like chmod 777 or chmod 755 or chmod -r The chown and chgrp commands may also be used with an asterisk (*) to change the permissions or group of all files in a directory. For example, type cd /www to change to the /www directory. Then,.. Change Permission With the find Command To assign separate permissions to directories and files, you can use the find command. The basic syntax includes using the find command to locate files/directories and then passing it on to chmod to set the permission: sudo find [directory] -type [d/f] -exec chmod [privilege] {}

The chmod command allows you to change the permissions on a file using either a symbolic or numeric mode or a reference file. We will explain the modes in more detail later in this article. The command can accept one or more files and/or directories separated by space as arguments Set read,write,execute permission as required, (ugo) u=user, g=group, o=others. sudo chmod 750 html Set the GID of html, now, newly created files in html will inherit ownership permissions: sudo chmod g+s html This creates the default rules for newly created files/dirs within the html directory and sub directories

How to Change Permissions and Owners via Linux Command Lin

  1. To assign reasonably secure permissions to files and folders/directories, it's common to give files a permission of 644, and directories a 755 permission, using the find command and a pipe we can target just files or just folders as in the following examples. $ sudo find /path/to/Dir -type f -print0 | xargs -0 sudo chmod 64
  2. Permissions Problems . In Linux, both directories and files incur permissions. Generally speaking, any file or directory may be readable, writable, or executable to you, depending on whether you're the owner of the object, a part of a group given access to it, or a globally authorized user
  3. Use chown to change ownership and chmod to change rights. As Paweł Karpiński said, use the -R option to apply the rights for all files inside of a directory too. 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
  4. To change file and directory permissions, use the command chmod (change mode). The owner of a file can change the permissions for user (u), group (g), or others (o) by adding (+) or subtracting (-) the read, write, and execute permissions

In Linux, who can do what to a file or directory is controlled through sets of permissions. There are three sets of permissions.

Each file in Linux has 3 types of owners, it's user, group, and others. A user is the owner of the file, and group is the one to which the user belongs to. Each file and directory has three permissions for all three owners, such as read, write, and execute Every file is owned by a specific user (or UID) and a specific group (or GID). The chown command can be used to change just the user or the user and group of a file. Here is an example of changing the owner of file file1 to user and its user to users The chmod command allows you to change the permissions of files using symbolic or numeric mode. To recursively operate on all files and directories under a given directory, use the chmod command with the -R, (--recursive) option.

The Group contains a group of users who share the same permissions and user privilege. Others means the general public
  4. First try to find the permission that you have for this folder and its subsequent files using this command: ls -lrt Try to see if there is a sticky bit associated with it. Then change to root using: sudo su And then give permission as: chmod +rwx filename That should do it

In this lesson we will focus on one of these, called the octal notation method Giving groups permissions to directories. Let's say you have the directory /READERS and you need to allow all members of the readers group access to that directory. First, change the group of the folder with the command: sudo chown -R :readers /READERS . Next, remove write permission from the group with the command: sudo chmod -R g-w /READER

You really shouldn't set 777, it would probably be better to just change the ownership of that directory to the www account.. Anyway your changes in the Dockerfile really don't matter, because you have a volume (appdata:/var/www) meaning that the permissions you have in the image are masked by your volume.Your docker exec -it myapp /bin/sh would be failing because that image is running as www.
