Attempting to do so: * In numeric representation, the sticky bits are represented by a 4th octal digit (e.g., 2777 vs. 777) (notice the extra octal digit is at the front) * In (the binary representation of) that octal digit, the first bit is for user, the second for group, and the last for world (IIUC) * In the alphabetic representation, a 4th group of three letters is *not* added, but instead the appropriate x is substituted by a t or s to indicate the bit is set, *and* * (IIRC) that t or s is uppercase or lowercase depending on whether the x bit for that group is set or not (and I don't recall whether uppercase or lowercase indicates the x bit is set, but I'd lean towards uppercase). regards, Randy Kramer > > On Tuesday 11 May 2004 9:11 am, Antonio Rodriguez wrote: > > > > > BTW, the "sticky bits" are overlaid on top of these to create the extra > > > digit... > > > 4 2 1 > > > rwx rwx rwx > > > > can you be more explicit? > > Sure, I'll try.... the first rwx is the 4's place, the second rwx is the 2's > place, and the third rwx is the 1's place... it's another 3 digit binary > number overlaid on TOP of the exisiting permissions. > > so, "group" sticky would be. > > 0 1 0 > > which gives us a 2. > > "user" sticky would be a 1 0 0 or, 4, this is mostly used to make stuff run > "setuid" by another user (usually root) > > and "other" sticky (used by the /tmp directory..shows up as a t in the > permissions list) would be 0 0 1 or 1 > > rwsrwsrwt would be what it would look like at 7777 > > I hope that makes more sense. > > > > > > so group sticky would be 2777 in this example... and it prints as > > > > > > rwx rws rwx > > > > Very unclear.
