NAME

       sotruss - trace shared library procedure calls

SYNOPSIS

       /usr/bin/sotruss [-f] [-F bindfromlist] [-T bindtolist] [-o outputfile] executable [ executable arguments...]

DESCRIPTION

       sotruss	executes  the  specified command and produces a trace of the library calls that it performs. Each line of the trace output reports
       what bindings are occurring between dynamic objects as each procedure call is executed. sotruss traces all  of  the  procedure  calls  that
       occur  between dynamic objects via the Procedure Linkage Table, so only those procedure calls which are bound via the Procedure Linkage Ta-
       ble will be traced. See Linker and Libraries Guide

OPTIONS

       -F bindfromlist	       A colon-separated list of libraries that are to be traced.
				Only calls from these libraries will be traced.  The default is to trace calls from the main executable only.

       -T bindtolist	       A colon-separated list of libraries that are to be traced. Only calls to these libraries will be traced.
				The default is to trace all calls.

       -o outputfile	       sotruss output will be directed to the outputfile. If this option is combined with the  -f option then the  pid	of
			       the executing program will be placed at the end of the filename. By default sotruss output is placed on	stderr.

       -f		       Follow  all children created by	fork() and print  truss output on each child process.  This option will also cause
			       a  pid to be output on each truss output line.

EXAMPLES

       Example 1: An example of sotruss.

       A simple example shows the tracing of a simple ls command:

       % sotruss ls | more
       ls	     ->       libc.so.1:*atexit(0xef7d7d1c, 0x23c00, 0x0)
       ls	     ->       libc.so.1:*atexit(0x1392c, 0xef7d7d1c, 0xef621bb0)
       ls	     ->       libc.so.1:*setlocale(0x6, 0x1396c, 0xef621ba8)
       ls	     ->       libc.so.1:*textdomain(0x13970, 0x1396c, 0xef621ba8)
       ls	     ->       libc.so.1:*time(0x0, 0xef61f6fc, 0xef621ba8)
       ls	     ->       libc.so.1:*isatty(0x1, 0xef61f6fc, 0x0)
       ls	     ->       libc.so.1:*getopt(0x1, 0xeffff8fc, 0x13980)
       ls	     ->       libc.so.1:*malloc(0x100, 0x0, 0x0)
       ls	     ->       libc.so.1:*malloc(0x9000, 0x0, 0x0)
       ls	     ->       libc.so.1:*lstat64(0x23ee8, 0xeffff7a0, 0x0)
       ...
       ls	     ->       libc.so.1:*printf(0x13a64, 0x26208, 0x23ef0)
       ls	     ->       libc.so.1:*printf(0x13a64, 0x26448, 0x23ef0)
       ls	     ->       libc.so.1:*exit(0x0, 0x24220, 0x2421c)

NAME

     truss -- trace system calls

SYNOPSIS

     truss [-facedDS] [-o file] [-s strsize] -p pid
     truss [-facedDS] [-o file] [-s strsize] command [args]

DESCRIPTION

     The truss utility traces the system calls called by the specified process or program.  Output is to the specified output file, or standard
     error by default.	It does this by stopping and restarting the process being monitored via ptrace(2).

     The options are as follows:

     -f      Trace descendants of the original traced process created by fork(2), vfork(2), etc.

     -a      Show the argument strings that are passed in each execve(2) system call.

     -c      Do not display individual system calls.  Instead, before exiting, print a summary containing for each system call: the total system
	     time used, the number of times the call was invoked, and the number of times the call returned with an error.

     -e      Show the environment strings that are passed in each execve(2) system call.

     -d      Include timestamps in the output showing the time elapsed since the trace was started.

     -D      Include timestamps in the output showing the time elapsed since the last recorded event.

     -S      Do not display information about signals received by the process.	(Normally, truss displays signal as well as system call events.)

     -o file
	     Print the output to the specified file instead of standard error.

     -s strsize
	     Display strings using at most strsize characters.	If the buffer is larger, ``...'' will be displayed at the end of the string.  The
	     default strsize is 32.

     -p pid  Follow the process specified by pid instead of a new command.

     command [args]
	     Execute command and trace the system calls of it.	(The -p and command options are mutually exclusive.)

EXAMPLES

     # Follow the system calls used in echoing "hello"
	   $ truss /bin/echo hello
     # Do the same, but put the output into a file
	   $ truss -o /tmp/truss.out /bin/echo hello
     # Follow an already-running process
	   $ truss -p 34

HISTORY

     The truss command was written by Sean Eric Fagan for FreeBSD.  It was modeled after similar commands available for System V Release 4 and
     SunOS.
