Every time I try to decipher S_I* combos I cry in pain. Often I just
refer to include/linux/stat.h defines to find out what mode it is
because numbers are actually quickier to understand.
Compare and contrast:
0644 vs S_IRUGO|S_IWUSR vs rw_r__r__
I'd say #2 really sucks.
Damn right.
I'd be very happy to remove (or #ifndef __KERNEL__ as needed) the
dreadful S_FOO macros. I'd be much happier with plain old octal,
as is normally used for both syscalls and the chmod command.
(the non-octal nonsense was probably invented for porting
software to non-UNIX systems)
If you like the ls way though, you might as well add the file
type notation: drwxr_xr_x, _r__r__r__, _rw_r__r__, etc.
That's not too bad. Plain octal is best though.
