6 * $Id: sh_syscalls.d 25 2007-09-12 09:51:58Z brendan $
8 * USAGE: sh_syscalls.d { -p PID | -c cmd } # hit Ctrl-C to end
11 * FILE Filename of the shell or shellscript
12 * TYPE Type of call (func/builtin/cmd/syscall)
14 * COUNT Number of calls during sample
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.
