I want to capture PID of a program and kill it using the PID if the program is been executing beyond 5 seconds.The problem I'm facing is I have another copy of the same program running under different shell script, and the above code is killing both the process. How do I specifically kill the program which has started under the current running shell script.

I want to kill parent process after "fork()" method. but if I kill parent process with "exit(0)" method, main() thread is terminated as well so child prosess doesn't work anymore. Is there any way to kill only parent process without affecting to child process?

In the comments section of this blog, the commenter "Pratik" claims that you can edit a running bash script, without killing it, and have the changes picked up by the running script. He claims you can do this by editing files in /proc. Now, I know how to find the /proc folder that contains the data on the running process, Code: cd /proc/`pgrep process_name` But I can't figure out what I should do if I want to edit a running bash script.

View 1 Replies View RelatedI haveing a big problem atm (just after to upgrade to 10.04). I have a simply and easy script that sent a halt command to every KVM virtual machine actually running into the server. this script is/and was) palced as a init-rc script in rc0/rc1 and rc6 lvls. Just after to upgrade, I have noticed that this script is executed but the system ignore the time that it require to finish (giving time to correctly stop a single virtual machine). Aftert 5 second it start sending SIG-TERM and SIGN-KILL to any currect process and then reboot/halt.
I have just done a new script using upstart and I got just the same result. What is happending? why is the waiting the init secuence for a valid/or_not termination of any init script. I am so sorry for this crap english I have never study this language so I try to do my best anytime I speak it (or try ti..).
I have some heavy, long processes running on remote Linux machines. I use my laptop to SSH to these machine and run the processes from my couch.
BUT, when I want to shutdown my laptop, I am in trouble since the remote processes are killed.
I did my research and found out that "screen" is a great solution for me, it is! (As long as I don't SHUTDOWN my laptop). Isn't there a way to "persist" the "screen" sessions so I can shut it down and then re-attach to a session?

Now i am finding the case where url is not responding and that output is not available to me in the file and on console i am getting "Could not connect to host".
Now I want to modify my urls.txt to have two fields:
Name and URL

URL3 : NOT CONNECTED
user@host$ killall -9 -u user Will it definitely kill all processes owned by user (including forkbombs)?
No new processes is spawned to user from other users. No user's processes are in D-sleep and unkillable.No processes are trying to detect and ptrace or terminate this started killall (but they can ptrace or do other things with each other) There is ulimit that prevents too much processes (but killall is already started and allocated it's memory)
E.g. if killall will finish untampered and successfully is it 100% that no processes are left with this uid? If no, how to do it properly (with standard commands and no root access). Will SysRq+I definitely kill all things (even replicating)?
I have a file which contains a table
row1 ✔ no ✔ no

I want local programmatic access to ssh output in Mac Terminal. First, I tried redirecting the output of each command to a file. The file was perfect, but of course it was on the remote server, and an sftp for each command output seemed a little.. Next, I tried to Applescript Terminal, but it only gives access to the currently visible text in a tab (i.e. if half the output has already scrolled out of sight, it doesn't get returned - useless).
Last, I tried piping ssh to tee (e.g. ssh user@host | tee output.txt). This almost worked. I have the output in a local file, but there are a lot of unwanted characters mixed in. For example, every time I hit backspace, there's a ^H in the file. There's also text like "[0m[K" which is harder to get rid of.
I'd like to make an indirect control for Emacs (in Ubuntu Linux) so that I can swipe some text in an xterm with the cursor, cutting it into the X cut buffer, then run a macro in Emacs to parse the cut buffer text to look for text saying "line XXXX" where X is all digits, then go to that line in the current Emacs buffer. I think this is possible by using emacsclient to get emacs to run a macro, then the macro parsing the cut buffer, then issuing a goto-line command to the number that's been parsed. My problem is I don't know how to write the emacs script to read the X cut buffer and parse it.. I've been going through cookbook examples but none seem to fit.
My goal is to ease development. When I have an error/information/status message printed in an xterm, I want to swipe the error message which says something like "syntax error on line 2776" then press a keyboard shortcut which Ubuntu will interpret to launch emacsclient, which causes my already-open Emacs to grab that text, parse it, and go to the line number I just swiped. Only this last step of parsing is the hard part. (Yes, I know you can run a shell INSIDE of emacs, but this is doesn't fit my workflow). How would I make emacs look at that X cut buffer and parse out the line number and issue the "goto-line" command to the current buffer?
I'm just wondering if there is a video capturing program that can, at the least record what is on my computer screen (including what is on Wine) and at the most capture what is on my webcam as well.

Assume that there's a while(1) inside the program being run. Now if I try to close the shell, it warns me that it'll kill my running program too! So, how to kill the shell and still let my program continue running in the background?
I tried exec ./a.out 10 but the shell is still there. Another alternative is to simply double click my executable but then how will I pass command line parameters?
one tell me the internal working of kill command. that is how it kills a process internally or from where it picks file to continue its process.

Description of what the code does or what i intended to do:
1. Created a child process from parent process using 'fork()'
2. Sent a signal 'SIGALRM' from child process to parent process using 'sigqueue' function.
(The Third parameter of 'siqueue' function contains the message (message msg) which the child process wants to send to the parent process.'msg' is a stucture instance containing a) pid of child and b) string) 5. Print the 'msg' sent by child process inside the signal handler function 'sig_action_function' of the parent process I am getting some junk value when this line is executed
Code:
printf("%d
",msg->cpid);
I expected to get the pid of child process, which the child process sent to parent process through the signal.
as we all know Process Scheduler does Process scheduling and its a process as well. I was just wondering that if this happens then the Process "Process Scheduler" should be a part of Process queue as well.
So if there are 5 process are there in Process queue & process scheduler is administrating them then since its also a process, once it puts a process under RUN state it should itself go inside queue because at one instant only one process can get executed on a processor. This is quite confusing for me. Please help me out. I tried to search on this but could not find any relevant topics.
