+How to Create a Shared Directory for All Users in Linux
+============================================================
+
+As a system administrator, you may have a certain directory that you want to give read/write access to every user on a Linux server. In this guide, we will review how to enable write access to all users on a particular directory (shared directory) in Linux.
+
+This calls for setting the appropriate access permissions, and the most effective as well as reliable method to allocating a common group for all the users who will share or have write access to the specific directory.
+
+So, start by creating the directory and common group in case it doesn’t already exist on the system as follows:
+
+```
+$ sudo mkdir -p /var/www/reports/
+$ sudo groupadd project 
+```
+
+Then add an existing user who will have write access to the directory: /var/www/reports/ to the group project as below.
+
+```
+$ sudo usermod -a -G project tecmint 
+```

+
+Create Common Directory Group
+
+The flags and arguments used in the above command are:
+
+1.  `-a` – which adds the user to the supplementary group.
+2.  `-G` – specifies the group name.
+3.  `project` – group name.
+4.  `tecmint` – existing username.
+
+Afterwards, proceed to configure the appropriate permissions on the directory, where the option `-R` enables recursive operations into subdirectories:
+
+```
+$ sudo chgrp -R project /var/www/reports/
+$ sudo chmod -R 2775 /var/www/reports/
+```
+
+Explaining the permissions 2775 in the chmod command above:
+
+1.  `2` – turns on the setGID bit, implying–newly created subfiles inherit the same group as the directory, and newly created subdirectories inherit the set GID bit of the parent directory.
+2.  `7` – gives rwx permissions for owner.
+3.  `7` – gives rwx permissions for group.
+4.  `5` – gives rx permissions for others.
+
+You can create more system users and add them to the directory group as follows:
+
+```
+$ sudo useradd -m -c "Aaron Kili" -s/bin/bash -G project aaronkilik
+$ sudo useradd -m -c "John Doo" -s/bin/bash -G project john
+$ sudo useradd -m -c "Ravi Saive" -s/bin/bash -G project ravi
+```
+
+Then create subdirectories where the new users above will store their project reports:
+
+```
+$ sudo mkdir -p /var/www/reports/aaronkilik_reports
+$ sudo mkdir -p /var/www/reports/johndoo_reports
+$ sudo mkdir -p /var/www/reports/ravi_reports
+```
+
+Now you can create files/folders and share with other users on the same group.
+
+That’s it! In this tutorial, we reviewed how to enable write access to all users on a particular directory. To understand more about users/groups in Linux, read [How to Manage Users/Groups File Permissions and Attributes][2].
