It's very rarely needed to use 'chmod 777' - especially if you are
not very familiar with these octal permission modes, then please
forget using 777: it makes the file readable, writable and executable
by the owner, the group and everyone else; you'll see this as "rwxrwxrwx"
in an "ls -l" listing.

So in your case, I'd probably at least do a "chmod go-w" on that
file for security reasons.

Did you mean "chmod +x" instead? This would make the file executable.

root can change the permissions on any file, any normal user can
only change the permissions if she is the owner.
