To review or change the permissions set for files and directories on Linux systems:
1.Go to Files.
The permissions set for files and directories are shown in the Permissions column. They are represented as three sets of symbols, for example, ‘rwx rwx r–’. The first set tells what the owner of the file or directory can do with it; the second tells what the user group, the file or directory belongs to, can do with the file or directory; the third set indicates what other users (the rest of the world, that is, Internet users, visiting a site) can do with the file or directory. R means the permission to read the file or directory, W means the permission to write to the file or directory, and X means the permission to execute the file or look inside the directory.
2.Locate the file or directory for which you want to modify permissions and click a hyperlink in the Permissions column.
3.Modify the permissions as desired and click OK.
To set access permissions for a file or directory on Windows systems:
1.Go to Files, locate the file or directory for which you want to set access permissions, and click the arrow in the corresponding row.
2.Click Change Permissions in the drop-down menu.
Do the following:
To make the file or folder inherit permissions from a parent folder (if it does not), select the checkbox Allow inheritable permissions from the parent to propagate to this object and all child objects. Include these with entries explicitly defined here.
To make the files and folders, which are contained in this folder, inherit the folder permissions you define, select the checkbox Replace permission entries on all child objects with entries shown here that apply to child objects.
To change or remove permissions from a group or a user, click the required name in the Group or user names list. If the group or user is not listed in the Group or user names list, select the required user or group name from the menu located above the list and click : the user/group appears in the list. Select it.
To deny the permissions, which are inherited from a parent object as allowed, select the required checkboxes under Deny. This will override inherited permissions for this file/folder.
To allow the permissions, which are inherited from a parent object as denied, clear the Allow inheritable permissions from the parent to propagate to this object and all child objects. Include these with entries explicitly defined here checkbox: this removes the inherited permissions. Then select the required checkboxes under Allow and Deny.
