Changing file/folder permissions  

All files on UNIX (and UNIX variants) machines have access permissions. These tell the 

operating system how to deal with requests to access these files. There are three types of 

access:  

   Read   Denoted as r, files with read access can be displayed to the user.  

   Write   Denoted as w, files with write access can be modified by the user.  

   Execute   Denoted as x, files with execute access can be executed as programmes by 

the user.  

Access types are set for three types of user group: 

   User   the owner of the file.  

   Group   other files which are in the same folder or group.  

   World   everyone else.  

The web server needs to be able to read your web pages in order to be able to display them in 

a browser. The following permissions need to be set in order for your web site to function 

properly.  

   All HTML files and images need to be readable by others. The setting for this is 644 

(readable by User, Group, and World, and writable by User), and is set automatically 

when you upload files.  

   All folders need to be executable by others. The setting for this is 755 (readable by User, 

Group, and World, writable by User, executable by User, Group, and World), and is set 

automatically when you create a folder.  

   All CGI files (all files in the cgi bin folder) need to be executable by other. The setting for 

this is 755 (readable by User, Group, and World, writable by User, executable by User, 

Group, and World), and is not set automatically when you upload files. You need to 

change file permissions manually. Refer to the 

Introduction to CGI

 topic for more 

information.  

Warning: It is important that none of your files or folders are writable by anyone else. Any file or 

folder which is writable by others can be erased by them. Generally there is no problem, just be 

careful in how you set your permissions.  

To change file or folder permissions: 

1.  Navigate to the file or folder that you need to change.
