I’m not sure how you dump all the memory to a file without doing this repeatedly (if anyone knows an automated way to get gdb to do this please let me know), but the following works for any one batch of memory assuming you know the pid: $ cat /proc/[pid]/maps This will be in the … Read more
This should work on Linux and SysV5 ps -ef –sort=start_time
I know this is an old thread, but in case anyone else is having the same issue, I had… What may be happening is that your process had a TCP port open when it crashed or otherwise exited without explicitly closing it. Normally the OS cleans up these sorts of things, but only when the … Read more
What can be simpler than echo $!? As one line: myCommand & echo $!
While top is running, you can press c to toggle between showing the process name and the command line. To remember the toggle state for next time, press W to save the current configuration to ~/.toprc.
The best method is to start the process in a terminal multiplexer. Alternatively you can make the process not receive the HUP signal. A terminal multiplexer provides “virtual” terminals which run independent from the “real” terminal (actually all terminals today are “virtual” but that is another topic for another day). The virtual terminal will keep … Read more
cat /proc/<pid>/environ If you want to have pid(s) of a given running executable you can, among a number of other possibilities, use pidof: AlberT$ pidof sshd 30690 6512 EDIT: I totally quote Dennis Williamson and Teddy comments to achieve a more readable output. My solution is the following: tr ‘\0’ ‘\n’ < /proc/<pid>/environ
Edit: The question was a little confusing, so I’m answering it two different ways. OS-level threads vs Green Threads For clarity, I usually say “OS-level threads” or “native threads” instead of “Kernel-level threads” (which I confused with “kernel threads” in my original answer below.) OS-level threads are created and managed by the OS. Most languages … Read more
Summary: In your case I would recommend to use execvp. To find out the differences between the exec* functions you should read the documentation:https://linux.die.net/man/3/exechttps://linux.die.net/man/2/execve The difference between execl* and execv* is the argument passing. execl* require a list of arguments while execv* require a vector of arguments.A list of arguments is useful if you know … Read more
In order: pid: The is the process ID (PID) of the process you call the Process.pid method in. ppid: The PID of the parent process (the process that spawned the current one). For example, if you run ruby test.rb in a bash shell, PPID in that process would be the PID of Bash. uid: The UNIX ID of the … Read more
