The following code can be used to create a daemon that will watch for processes that show up in the "ps -ef" output with certain characteristics. When it identifies such processes, it will attach to them with a trace utility (i.e. strace, truss, tusc... you must change the code to reflect this on whatever platform this is run on). The tool does not follow these processes with a fork since it will trace any children that contain the same "ps -ef" characteristics. This makes it useful for tracing DS PX programs that contain rsh since truss's fork flag (i.e. "-f") blocks the rsh from executing.
The script below should be saved to a file such as /tmp/tracer.sh and given rwx permissions. The trace utility name that is appropriate for your platform should be altered in the "ps -ef" command and in the "for" loop. The script would then be run using this syntax:
/tmp/tracer.sh <search string>
As mentioned above, the search string can be any value that would appear in the "ps -ef" output. Such values might be a user id, particular time, a command, or arguments to a command. The fifth and eight lines of this script gather lists of all commands to be traced and then attempts to remove commands that should be ignored. If you find too many processes getting traced, identify why it was selected and then alter these two lines by adding a "grep -v" to the list of items bieng ignored.
