NAME
     extrace – trace exec() calls system-wide

SYNOPSIS
     extrace [-deflqtu] [-o file] [-p pid | cmd ...]

DESCRIPTION
     extrace traces all program executions occurring on a system.

     The options are as follows:

     -d      Print the current working directory of the new process.

     -e      Print environment of process, or ‘-’ if unreadable.

     -f      Generate flat output without indentation.  By default, the line
             indentation reflects the process hierarchy.

     -l      Resolve full path of the executable.  By default, argv[0] is
             shown.

     -q      Suppress printing of exec(3) arguments.

     -t      Also display process exit status and duration.

     -u      Also display the user running the process.

     -o file
             Redirect trace output to file.

     -p pid  Only trace exec(3) calls descendant of pid.

     cmd ...
             Run cmd ... and only trace descendants of this command.

             By default, all exec(3) calls are traced globally.

EXIT STATUS
     The extrace utility exits 0 on success, and >0 if an error occurs.

ERRORS
     Check these prerequisites if you see this error:

           binding sk_nl error: Operation not permitted

     extrace requires special permissions to run, either root or the Linux
     CAP_NET_ADMIN capability.

     extrace only works on Linux kernels with the kernel options

           CONFIG_CONNECTOR=y
           CONFIG_PROC_EVENTS=y

BUGS
     While process tracing is exact, looking up all information is inherently
     sensitive to race conditions.  In doubt, you can only trust the PID was
     written correctly.

PWAIT(1)                    General Commands Manual                   PWAIT(1)

NAME
     pwait – wait for processes to terminate

SYNOPSIS
     pwait [-v] [-c] pid ...

DESCRIPTION
     pwait waits until each of the given processes has terminated.

     The options are as follows:

     -v      Print the exit status when each process terminates.

     -c      Return 111 if any process exited non-successfully.

EXIT STATUS
     The pwait utility exits 0 on success, and >0 if an error occurs.

     Invalid pids elicit a warning message but are otherwise ignored.

ERRORS
     Check these prerequisites if you see this error:

           binding sk_nl error: Operation not permitted

     pwait requires special permissions to run, either root or the Linux
     CAP_NET_ADMIN capability.
