Programming :: Alter A Running Process Without Killing It?

Sep 7, 2010

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.

Ubuntu :: Killing All The Process On Restart/halt/shutdown Instead Waiting For Scripts?

May 9, 2010

I 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..).

Programming :: Process P4 To Terminates Processes P1, P2, P3 If They Are Running?

Aug 18, 2009

I have p1,p2,p3,p4 some processes created by me in C. p1, p2, p3 are started individually from several consoles. And I want process p4 to terminates processes p1, p2, p3 if they are running. Which is the easiest way to accomplish that? put all processes in the same process group and send from p4 a kill signal to the group. But I couldn't do that because I cannot call successfully setpgid(getpid(), 15000) from p1-p4. It's there some way to put them in the same group? the processes don't have a child-parent relationship, they are launched manually from consoles.

Programming :: Exit My Script W/o Leaving An Orphan Process Running

Dec 4, 2010

It's called TextRipper and it creates indexable and editable text files from any image. Feel free to copy TextRipper; it's licenced under GPL. My troubles are with cracking passworded pdf's. (As you can see, I meant any when I said any image.)

I can't find a way for the user to cancel the decryption process by exiting the script without pdfcrack orphaning. Line 349 works the rest of the time; the concerned process is line 228. I believe it's a piping/subshell problem. At least that's how I've been going at it in vain.

I've made portability a priority and that the comments still require updating.

Code:

If the result is one output file, TextRipper will open it for you in OpenOffice Writer.

Otherwise all txt output files (editable and indexable) will be in the original file's directory." 0 0

General :: Continue Running A Program Inspite Of Killing The Shell Which Invoked It?

May 31, 2011

Possible Duplicate: Leave bash script running on remote terminal while not logged in? I run a program, say ./a.out 10 from the shell prompt. 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?

Programming :: Panic - Killing Interrupt Handler - Not Syncing

May 10, 2010

I have written a Linux kernel module (in Linux 2.4, Red Hat 9) which does the followings: It takes srcIP, sourceport, destIP, destport and loadvalue as command line arguments. If configured load value is greater than 1, it creates different channels (i.e. No of UDP channels created equals to configured load value), assign different source port and destination port to different channels and send UDP datagram in different channels. Say for example the configured parameters are as follows srcIP=10.17.17.43 destIP= 10.17.17.44 sourceport=10000 destport= 20000 loadvalue=2.

Then it creates two UDP different channels and transmits UDP packets (in every 20 milliseconds) to destination IP address (i.e., 10.17.17.44) with source port 10000, destination port 20000 in one channel and source port 10002, destination port 20000 in another channel. When I configure to pass ?loadvalue=500? and run the module, I get the below kernel panic message in system log file (i.e., var/log/messages) 0>Kernel panic: Aiee, killing interrupt handler! In interrupt handler - not syncing. Running the same linux kernel module ,in 1000 loadvalue, I get this message, eth0: Out-of-sync dirty pointer, 49937 vs. 49954 in text console. I am unable to catch the root cause of these problems and how will I solve these?

Debian :: Running Same Process Multiple Times(from Another Account) / An Instance Of Newsbeuter Is Already Running Error?

Aug 6, 2010

Sometimes I connect to my Debian box from another computer (using SSH on Cygwin or Linux), and once ina while I want to run some console apps. And sometimes some of these apps might complain about "another intance, Error: an instance of newsbeuter is already running (PID: 2496)". Is there a work around for this issue at all(without killing the original instance") ? The reason I do not want to kill the app because there might be 2 users connected to the same machine that might be using the same app.

Programming :: Under Which Circumstances A Child Process Creates Another Child Process Using Fork

Dec 7, 2009

Consider the following code:

Code:

int main()
{
int i=0;
pid_t pid;
for(i=0;i<2;i++)

[code]....

I get the following output:

Parent: chid_pid=4356 i=0 parent's pid=4355
This is child 4356 i=0
This is child 4357 i=1

[code]....

I can observe instead of two children(as I expect) processes there are three. This is because child process 4356 creates its own child. Why all the messages of the type "This is child X i=Y" are concentrated one under another? How exactly fork works? Is affected by the fact that I have a dual-core processor?

Ubuntu :: Keep A Process Running From Ssh

May 21, 2010

I recenlty set up a headless linux home server by my router will my spare computer parts. I have NFS and even a COD4 server running on it for my friends and me. Because the box is headless, I take controll over it with ssh and start the COD4 server from there, but the problem is, if I close the terminal I have the ssh running from, it closes my server, meaning my desktop needs to be up and running the entire time. That kinda ruins the point of my server

So my question is, is there a way for me to run the command so that it will not close with the terminal AND that I can still send commands to the server.
