The truss command is available in AIX starting in at version 5.1. The following shell script emulates the truss functionality in AIX 4.3.
--------------------------------------------------------------------------------
#!/bin/ksh
# Name: truss.sh
# Purpose: to make AIX trace look like the truss command
# Caveat: Unsupported tool. Use at your own risk.
