problem with chmod command

I don't know what is happening

experimentx@workmateX:/var/www$ sudo chmod 0777 -r /var/www/ chmod: cannot access `0777': No such file or directory experimentx@workmateX:/var/www$

Use this:

sudo chmod 0777 -R /var/www/ 

-R instead of -r.

Use "-R" instead of "-r".

From the chmod help:

-R, --recursive change files and directories recursively

Also note that the 0 will no longer clear suid/sgid/sticky in recent versions of chmod and you'll soon have to use a symbolic mode (if that's what you're intending to do).

• coreutils bug#8391: chmod setuid & setguid bits
• Red Hat Bug 691466 - [RFE] Enable octal-digit mode for removal of UID/GID/sticky bits

Perhaps going or directing the file in terminal and once you locate file by:

ls 

then run the command:

chmod +x filename 

from that location I'm sure it will work.
