trace

trace(1)						      General Commands Manual							  trace(1)

Name
       trace - trace system calls of programs

Syntax
       trace [options] cmd args...

Description
       The  command  with  no flag arguments traces for the given cmd and args all system calls made and prints a time stamp, the PID, call and/or
       return values and arguments and puts its output in the file trace.dump.

Options
       -f filename
	       Puts dump in file filename.

       -z      Echos arguments only.

       Only one of the following option arguments can be specified at one time.

       -c#     Traces given PIDs and their children.  Up to sixteen PIDs can be specified.

       -g#     Traces given groups only.  Up to sixteen Group IDs can be specified.

       -p#     Traces given PIDs only.	Up to sixteen PIDs can be specified.

       -s#     Traces given system calls only.	Up to sixteen PIDs can be specified.

       -u#     Traces given UIDs only.	Up to sixteen PIDs can be specified.

Examples
       trace -f ls.dump ls -l /dev >ls.out
       runs the cmd ls -l /dev and puts the trace in ls.dump and output in ls.out.
       trace -f csh.trace -p $$ &
       will trace your login shell in the background. To stop the trace just send it a termination signal (that is, kill -TERM trace_pid).

Restrictions
       Due to security, no one, not even the super-user can trace anyone else's programs. This sort of negates some of the usefulness  of  the	-g
       and -u flags.

       The program cannot be traced.

       Only 16 numbers can be given to the -c, -p, -g, -u, and -s flags.

       The kernel configuration file must contain the following:
       options	       SYS_TRACE
       pseudo-device   sys_trace

       In addition, the superuser must use the following command sequence to create the device:
       cd /dev
       MAKEDEV trace
       If both lines are not in the configuration file or if the device is not made, the message "Cannot open /dev/trace" appears.

Files
       /dev/trace     read only character special device for reading syscall data.

       trace.dump     default file for the system call trace data.
