-
- It should be included with any SVR4. It is a 'user' command, check
- the man page truss(1). It's in the SVR4 User's reference manual
- (c)1990, so it could have been there from the start. Since that
- manual is not processor specific, I assume it should be available on
- any architecture.
-
- However, I have noticed its absence on DataGeneral's DG/UX (running
- on AViiONs 88k). It seems that truss(1) is not available if the proc
- filesystem has not been implemented. Is /proc available on the Harris?
-
- I know that truss is available on most i386 PC based SVR4s and on
- Solaris 2.1 (Sparc and i386 version).
-
- Guess truss hasn't made it to SVID 3...
