sotruss(1) User Commands sotruss(1)NAMEsotruss - trace shared library procedure calls
SYNOPSIS
/usr/bin/sotruss [-f] [-F bindfromlist] [-T bindtolist] [-o outputfile]
executable [ executable arguments...]
DESCRIPTIONsotruss 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 Table 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 output‐
file. 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)
