About this tool

chmod 777 (rwxrwxrwx) gives everyone full control: anyone on the system can read, change and run the file. Avoid it on servers. 755 for folders and 644 for files is almost always what you need.

How to use it

  1. 1 Tick the permissions you want, or type a number such as 755.
  2. 2 Copy the chmod command.
