No.

Not exactly.  More precisely, it will remove the write permissions for
all.

I'm assuming that you're not using the exact syntax that you have
above.  This works for me:


$ ls -l
total 23302
-rwxr-xr-x  1 lhall None    72393 Jun 17 12:46 a.exe*
-rw-r--r--  1 lhall None       84 Jun 17 12:45 helloworld.c
-rw-r--r--  1 lhall None      587 Jun 17 12:45 helloworld.o

$ attrib
A            C:\tmp\junk\a.exe
A            C:\tmp\junk\helloworld.c
A            C:\tmp\junk\helloworld.o

$ chmod -w *

$ ls -l
total 23302
-r-xr-xr-x  1 lhall None    72393 Jun 17 12:46 a.exe*
-r--r--r--  1 lhall None       84 Jun 17 12:45 helloworld.c
-r--r--r--  1 lhall None      587 Jun 17 12:45 helloworld.o

$ attrib
A            C:\tmp\junk\a.exe
A            C:\tmp\junk\helloworld.c
A            C:\tmp\junk\helloworld.o

Of course, whatever your umask setting is comes into play as well.
