sh_calltime.d - measure Bourne shell elapsed times for types of operation. sh_calltime.d This traces shell activity from all Bourne shells on the system that are running with sh provider support. Filename and call names are printed if available. Any Evolving - uses the DTrace Shell provider, which may change as additional features are introduced. Check Shell/Readme to see what version these scripts are based on.

Default output, # sh_calltime.d

FILE Filename of the shell or shellscript

TYPE Type of call (func/builtin/cmd/total)

NAME Name of call

TOTAL Total elapsed time for calls (us)

See the DTraceToolkit for further documentation under the Examples, Notes and Docs directories. The example files may be especially useful as they aim to demonstrate how to interpret the output. sh_calltime.d will run until Ctrl-C is hit. Brendan Gregg [CA, USA] dtrace(1M)
