sh_syscalls.d - count Bourne calls and syscalls using DTrace. sh_syscalls.d { -p PID | -c cmd } Filename and function names are printed if available. The filename for syscalls may be printed as the shell name, if the script was invoked using the form "shell filename" rather than running the script with an interpreter line. 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_syscalls.d

FILE Filename of the shell or shellscript

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

NAME Name of call

COUNT Number of calls during sample

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_syscalls.d will run until Ctrl-C is hit. Brendan Gregg [CA, USA] dtrace(1M)
