Re: permission command

From 'chmod' man page:

t [Tru64 UNIX] Save text permission.

[Tru64 UNIX] In earlier versions of the UNIX system, setting this per-
mission bit caused the text segment of a program to remain in virtual
memory after its first use. The system thus avoided having to transfer
the program code of frequently accessed programs into the paging area.
A t appears in the execute position of the all others option to indi-
cate that the file has this bit (the sticky bit) set.

[Tru64 UNIX] If a directory has this bit set, then deletion in it is
restricted. An entry in a sticky directory can be removed or renamed
by a user only if the user has write permission for the directory and
the user is the owner of the file, the owner of the directory, or the
superuser.
