Open main menu


The chmod command (abbreviated from change mode) is a Unix command that lets a programmer tell the system how much (or little) access it should permit to a mediawiki file.[1]

Accessing filesEdit

With the WinSCP program, you can change permissions

If you are using FTP software, there is usually a menu option or button that says "Change Permissions," click this option. You have choices of R(read), W(write), and X(execute)[2].

If you are using a program such as PuTTy, you need to use the "chmod" command.[3]


Permission Command
Read permissions chmod 744 yourfile
Execute permissions[2] chmod 755 yourfile
Read/write permissions chmod 766 yourfile
All permissions chmod 777 yourfile


If you want to make everything under the ./www subfolder be 755: sudo chmod -R 755 ./www
