1N/A * sh_syscalls.d - count Bourne calls and syscalls using DTrace.
1N/A * Written for the sh DTrace provider.

1N/A * $Id: sh_syscalls.d 25 2007-09-12 09:51:58Z brendan $
1N/A *
1N/A * USAGE: sh_syscalls.d { -p PID | -c cmd } # 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/syscall)
1N/A * NAME Name of call
1N/A * COUNT Number of calls during sample
1N/A *
1N/A * Filename and function names are printed if available.
1N/A * The filename for syscalls may be printed as the shell name, if the
1N/A * script was invoked using the form "shell filename" rather than running
1N/A * the script with an interpreter line.
