/usr/bin/sotruss [-f] [-F bindfromlist] [-T bindtolist] [-o outputfile] executable [executable arguments...]
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 Table will be traced. See Linker and Libraries Guide
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.
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.
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.
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.
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)
