1N/A * This traces shell activity from all Bourne shells on the system that are
1N/A * running with sh provider support.
1N/A *
1N/A * USAGE: sh_calltime.d # hit Ctrl-C to end
1N/A *
1N/A * FIELDS:
1N/A * FILE Filename of the shell or shellscript
1N/A * TYPE Type of call (func/builtin/cmd/total)
1N/A * NAME Name of call
1N/A * TOTAL Total elapsed time for calls (us)
1N/A *
1N/A * Filename and call names are printed if available.
