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.
