I have a script that executed 100000 C Programs, reads the commands from a file and executes them. There is a requirement to measuer the time that each of this 100K C programs running.If it exceeds 120 sec I want to Kill that Process.Any Idea to embed this in my shell script?
View 4 RepliesI've done a lot of googling for this, but always found code that does not work on my compiler.Could anyone please post a small (working) program through which I can store the starting time of the program (milliseconds) and get the ending time of the program in integer variables?Am working on Fedora 8, and with the gcc compiler.

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?
Linux bash inline command to execute a program and limit the resource.As I know, to limit the resource I can use ulimit command.But, the problem is when I set the CPU time limit 1 second, and then I want to execute another program with CPU limit 2s, the ulimit command return an error like this: bash: ulimit: CPU time: cannot modify limit: Operation not permitted and absolutely my program killed in 1 second.So, How can I make the second program running with the CPU time limit 2 seconds?
View 3 Replies View RelatedI am a beginner to C and C++ and so far I have learned two ways to measure the time my program takes to run.
Method 1: Just compile your C file and if the executable is say a.out just type time ./a.out
Method 2: Here the general structure of the code is
Code:
#include<stdio.h>
#include<time.h>
int main(void)
[Code]....
Question 1 Do Method 1 and Method 2 return the same times?
Question 2 Method 1 gives three times real, usr and sys . Is it true that USR+SYS= TIME GIVEN BY METHOD 2
I have performed some experiments with small codes which return the squares of numbers uptill 36000 and I feel the answer to question 2 is yes
I am using a simple plain Debian Lenny base system (No X). I would like to measure how many seconds my system takes to boot - time between hitting enter key on GRUB screen to login console on tty1.One obvious way is to measure it manually by looking at your wrist watch or an external timer but I would to measure it more accurately - something that is built inside the Operating System.

So I open firefox from my bash shell with:
Code:
firefox google.ca
it opens firefox, I can browse, etc.
Now if I alt-tab back into my shell, i can't enter any commands in the shell.
I know that i can do this if I close firefox, but I want to keep working in my shell with firefox still open.
Is this possible?
I want to record an internet radio station starting at 2:00am tomorrow morning. The specific program on the radio station lasts until 6:00am. The command I need to run to record the station is: Code:mplayer http://wjcu.jcu.edu:8001/listen.pls -ao pcm:file=indie_heat_of_the_night.wav -vc dummy -vo nullI'd use cron, but 1. I'm not sure how to and 2. it seems unnecessarily complicated for something that I only want to run once. If cron is the only/easiest solution, I guess I'll just have to resort to that, but I'd rather not.

I am trying to access an aspx page which, when accessed with certain parameters in the URL, downloads a file. I need to do this with a shell script, rather than interactively. I tried using wget, but I get a response of 302 from the server, which redirects me to the default page and then downloads the default page html itself. I quickly tried curl which seemed to be doing the same thing. It works perfectly from browsers on either Linux or Windows. Originally, I had a problem with interpretation of ampersands in the URL, but I put quotation marks around the URL, so that isn't the problem now.
I cannot fix this on the server side, because the aspx page will be accessed on a variety of servers which are probably all set differently and which aren't under our control.
I've been having a bit of trouble running a shell script with cron. A friend of mine does a community radio show and the station has a live stream but no podcasts, so I've set up a script to record the stream and encode it as an mp3 while I'm away using mplayer and lame -that's what I'm trying to do anyway.
Here's the script, but it doesn't seem to run- at least, I don't see any of the files it should be outputing, would they be in the cron.weekly directory (where I have the script) or in my home directory?
#This is a script to record 'The Unnamed Show'
#it will record the show from the live stream, then convert the output #to an MP3
#Finally, it will delete any files no longer required HOME=/home/byron/
I have been playing around with shell scripting, nothing too complex just learning the basics. if i try to run a script as root (by entering "sudo" then the "command") it says command not found. i can only do it ass root if i specify the full path (/home/username/bin/command) im pretty sure the directory that my scripts are in are part of the superusers path.

I am new to bash scripting (not programming in general).
I am writing a bash script that will run a Python script I have written.
I want to be able to do the following:
Pass parameters to the bash script via the cronjob (so I can have two cron jobs) one to be run with parameter 'foobar', and the other 'foo'
switch based on the parameter passed to the bash script (by switching, I mean an if/else based on the paramter passed to the bash script).

How would I go about doing this? I have read many tutorials about scripting but I cannot seem to get it to work.
