Shell builtins, commands and lines are also printed. 12 * 13 * FIELDS: 14 * C CPU-id 15 * PID Process ID 16 * DELTA(us) Elapsed time from previous line to this line 17 * FILE Filename of the shell script 18 * LINE Line number of filename 19 * TYPE Type of call (func/builtin/cmd/line/shell) 20 * NAME Shell function, builtin or command name 21 * 22 * The filename for syscalls may be printed as the shell name, if the 23 * script was invoked using the form "shell filename" rather than running 24 * the script with an interpreter line. 25 * 26 * WARNING: Watch the first column carefully, it prints the CPU-id. If it 27 * changes, then it is very likely that the output has been shuffled. 28 * 29 * COPYRIGHT: Copyright (c) 2007 Brendan Gregg. 30 * 31 * CDDL HEADER START 32 * 33 * The contents of this file are subject to the terms of the 34 * Common Development and Distribution License, Version 1.0 only 35 * (the "License").
