I want to perform the following:grep -qsRw -m1 "parameter" /varBut before running the grep command I want to limit how long the grep process is to live, say no longer than 30 seconds.How do I do this?And if it can, how do I return or reset to have no time limit afterwards.

View 1 Replies View RelatedPossibly related to this previous question, I would like to be able to run a task for a specified amount of time, then stop/kill it, then start it again. Specifically, I run the Folding@Home application on my Linux workstation. Periodically, it will have trouble logging-in to the home server, and will sit idle for a long time, but not release memory/resources it has claimed (yes, I realize this is likely a bug in the tool, but I can't fix that currently). Typically just the act of killing and starting the tool will allow it to check-in again. So, I would like to be able to run something like:
run_for <time> ./fah6
Does such a tool exist, or should I write a wrapper than nukes the fah6 client after, say, a week and restart it?
I'm rather new to linux, and I have a dedi server. I know how to browse, install, remove etc, all the basics needed to use it. I've installed flvtool2, memcoder and ffmpeg, and at the moment im converting avi files in to flv. Im then passing metadata using yamdi.
However, this process is very timely as im converting loads of avi files at a time.Im looking for a script, or a way where I can execute one command/script and which will convert all files in the directory I specify, then run those converted files through yamdi.Im guessing it would be some sort of loop, and then changing for each file?
I am currently struggling with one of my tasks.I was asked to find a way how to determine how much time an _already running_ process is spending in user and kernel space.E.G. <some tool> <pid>[Control] + [c]<pid> spent 12.1 seconds in user and 1.52 seconds in kernel space.Does something like this exist? Basically I guess I am looking for something similar to time, except that the process is already running.So..a) Is there a tool which fulfills this task?b) Is there a way to write your own software which does the job? Is it even possible to code something I am looking for?I recently found strace -c -p <pid>, but well, this is not exactly what I was looking for.

The VM software in use is Xen, as supplied with the OS.The host machine's time and date is fine, however both Virtual Servers are running ahead of real time consitantly.Running /etc/init.d/ntpd restart will resolve the issue however one of these is running MailScanner and when the time suddenly goes backwards, sometimes by as much as an hour, it stops working properly.
View 1 Replies View RelatedScenario: ( in C++ code)
I need a process A to be able to get the start time of process B. I have the PID of the process B.
I would have thought there would be a simple system call to make by passing in the pid of Process B, but I don't thing there is??!!
So my other thought is to create a script that will be passed the pid and either I can read the file creation of /proc/<PID>/stat or I could also parse the start time of ps on the <PID>. This script can be ran from the C++ code. My difficulty is capturing this information in the C++ code. If I run exec ( or system if not a script) I need the results in a program variable....not stdout.
My only solution is write it to a tmp file and read it back into the program variable. Seems rather arguious but a least it would work.

Im looking for an app pr line of code that could let me observe a process, save the info in a number of variable and then put the gathered info on a file.
Ive been trying with variations of top but no luck. I am running several CentOS virtual servers, VM is 2gb ram 2 processor.
Maybe a script that works over a specified amount of time while writing lines with the info on a text file so at the end i can have a sort of table with the data.
The thing is Im going to stress test the server and I would like to have the data to make some statistics.
I've just installed CentOS 5.3 on my laptop and trying to connect to wireless internet connection at my home but I've found no success so far. I have a key on my laptop that turns blue when wifi is activated, but it is always red in linux so I guess I need to install some drivers, but I dont know what they are. When I use Windows, it automatically turns blue without doing anything. Also, yum doesnt work as well as its not connected to internet...
View 4 Replies View RelatedEver since the kernel update to 2.6.34.6-47.fc13.x86_64, my boot process hangs at about startx time. I boot cleanly at runlevel 3 in either this or the previous 2.6.33.8 kernel. If I execute startx from here (in either kernel), the system hangs at the same place. During the early troubleshooting, I read in another thread (250929) about installing xorg-x11-drv-catalyst, which I did using yum. This led to the failure of the 2.6.33 kernel; yum remove did not fix this. I have carefully followed the instructions in the fglrx HOWTO (updated a week ago by Hlingler) as they relate to a PAE kernel (including reinstalling mesa-libGL), and that fixed earlier difficulties. Hence, I felt I needed a new thread.
dmesg tells me

microcode: Microcode Update Driver: v2.00 .....
But the program itself reports
Code:
# microcode_ctl -h
This program is for updating the microcode on Intel processors belonging to the IA32 family - PentiumPro upwards (x86-64 included). It depends on the Linux kernel driver. The website urbanmyth.org/microcode (mentioned by yum info microcode_ctl) clearly indicates that Intel has taken over this microcodecode distribution, and suggests that it is no longer valid for AMD processors.
I found a reference to a kernel configuration flag CONFIG_MICROCODE_AMD (as a plausible subsititute for CONFIG_MICROCODE_INTEL) that possibly belongs in a script in /etc/init.d - but the above context leads me to suspect this is not true any more. In any event, those flags are not mentioned anywhere in my init.d scripts - in fact nowhere in the entire /etc tree. My microcode file exists, and is dated March 23. How do I get it installed? Or is this completely unrelated to my hanging boot problem, as suggested by the "platform microcode" line in the dmesg output? If so, where should I be looking?
eCouldnyone help me out to put the right configuration parameters in the grub.conf file so I can enable or disable the Fedora Logo on boot time ?

How can I do this?
I have an Acer Aspire netbook with 1GB RAM and 1.6 GHz dual-core 32-bit x86 chips. The KPackageKit / yum / rpm chain is running too slow for me. In addition to the time required to download any new packages or updates, it seems to require at least one full minute of processing time to install each package, update, or bug fix, no matter how small. Another full minute is consumed for each package in "cleaning up."Running yum from the command line takes nearly the same amount of time.During this time, I cannot run any other applications without severe thrashing. It seems that a full gigabyte of memory is in use with some 100M swapped out to disk.
Is there any way to reduce the running time and memory requirement of the update process?While not updating or installing software, I do not normally run out of memory (i.e. begin thrashing) until I have about a dozen browser tabs open, or the like.
I am trying to install CentOS 5.2 on an HP rp5700 desktop unit. These units were originally sold as a Point of Sales unit I believe, but HP also markets it as a high life cycle server for SMB market.I tried to load CentOS on this unit via CD (created from downloaded ISO of course). It presents the initial CentOS banner page and waits for the obligatory "enter" to continue. It begins the boot process up to discovering the PCI stuff and just locks up, no response. I have to power down to restart.Since this does not even get to the point of installing. I am at a loss what to do next. Has anyone had a similar issue with other PCs.The boot stops at the lineACPI: PCI Root Bridge [PCI0] (0000:00)

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.

View 2 Replies View Relatedas 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.
