Trace control in subcommand mode

If the trace routine is configured without the -a option, it runs in subcommand mode.

When running the trace routine in subcommand mode, instead of the normal shell prompt, a prompt of "->" displays. In this mode, the following subcommands are recognized:

trcon

Starts or resumes collection of event data

trcoff

Suspends collection of event data

q or quit

Stops collection of event data and terminates the trace routine

!command

Runs the specified shell command

?

Displays the available commands

# trace -f -m "Trace of events during mycmd"
-> !mycmd
-> q
#
