3 * sh_syscalls.d - count Bourne calls and syscalls using DTrace.
4 *                 Written for the sh DTrace provider.

7 *
8 * USAGE: sh_syscalls.d { -p PID | -c cmd }	# hit Ctrl-C to end
9 *
10 * FIELDS:
11 *		FILE		Filename of the shell or shellscript
12 *		TYPE		Type of call (func/builtin/cmd/syscall)
13 *		NAME		Name of call
14 *		COUNT		Number of calls during sample
15 *
16 * Filename and function names are printed if available.
17 * The filename for syscalls may be printed as the shell name, if the
18 * script was invoked using the form "shell filename" rather than running
19 * the script with an interpreter line.
