Hi,

According to "sticky bit" on wikipedia, sticky bit is obsoleted in UNIX world nowadays. However that item did not mention AIX at all, and I wonder why there's nothing on redbooks or AIX 5L wiki talking about the 'sticky bit' at all. So, would anyone tell where I can get relevant staff to read? Thanks

check the manpages for "ls" and "chmod". The ls manpage still references the "t" as a sticky bit. Under chmod, they don't call it a sticky bit. Instead, the term "save-text" is used.
It says when set on a directory, only file owners can link or unlink.

IBM's infocenter might have more information than the manpages if you need it.

Just to clarify

Sticky bit is the wrong terminology it's actually called setuid, if it is in owner's field then it will run the program with the effective owner's id who own's the program, and if it is set in group field then it will run the effective group id.

sticky bit represents 't' which is usually on directories, this means that only owner can link and unlink the files in that directory, only if it's turned on.

Hope this helps

On a additional note, as WikiPedia explains in the History section, sticky bit "t" represents, a executable will stay in memory even after termination. But in modern computers, with ample memory, this happens for most of the applications even without the sticky bit, so this does not make much of a sense for files. But I do believe still files can be set with a sticky bit.
