Many times a script's installation instructions or readme file will tell you that you need to change permissions on or chmod a file/directory so that the script can execute or write to the file/directory. You'll need to make these changes through the file manager or through ftp. Usually programs will display permission in an odd way such as this: _rwxrwxrwx In number form that's 777. You may or may not have the _ at the beginning. If you do, that means it's a file that has those permissions. If it's a directory you'll see a d there (drwxrwxrwx) instead of the underscore. Each group of 3 characters is the permissions for the user, the group and finally others (everyone else). In addition, each group of 3 characters make up one number. The following is what each letter equates to: r (read) = 4 w (write) = 2 x (execute) = 1 To give some examples of some common permission converted from the letters to numbers (with the first character removed to avoid some confusion): rwxrwxrwx -> 777 rwx_r_xr_x -> 755 rw_rw_rw_ -> 666 rw_r__r__ -> 644 As you see above, you just add up what each letter is equal to in each group to form the numbers.
