Dear ladies and gentlemen,
when executing
chmod +w file
or
chmod -w file
this has only effect on the write bit of the user - not to all (i.e. group
and others are not affected) (whereas +r,-r and +x,-x are working as expected
and set the permission for all)
Best regards,
David van Gorkom.
P.S.:
I'm not sure if this is a bug - my reference was the freebsd manual for
chmod, but I tested chmod (GNU fileutils) 4.0.35 under Linux.
http://www.freebsd.org/cgi/man.cgi?chmod
The relevant part from the chmod manual is:
[...]
The symbolic mode is described by the following grammar:
mode ::= clause [, clause ...]
clause::= [who ...] [action ...] action
action::= op [perm ...]
who::= a | u | g | o
op::= + | - | =
perm ::= r | s | t | w | x | X | u | g | o
[...]
The op symbols represent the operation performed, as follows:
+ If no value is supplied for perm, the ``+'' operation has no
effect. If no value is supplied for who, each permission bit spec-
ified in perm, for which the corresponding bit in the file mode
creation mask is clear, is set. Otherwise, the mode bits repre-
sented by the specified who and perm values are set.

- chmod (GNU fileutils) 4.0.35,
