I have a program that receives something like this from a settings file: "C:\Files\App 1\App.exe" "-param1:true -blah" It receives this all as 1 string, but the Process object in C# needs the program and the arguments passed separately. Is there an easy way in C# to parse this, or a way to just pass the statement as it is without pars...
I have a script (KSH script to be precise) that downloads 3 files from a FTP server, using the curl command. When I run manually my script, i.e. by executing the command ./ftp_download.sh XXX (XXX are the parameters for the script), the download finishes correctly. As I want to run the script from a Java program, I have made a short Ja...

I read that this portion of code can cause deadlock: Process p = new Process(); p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.FileName = "Write500Lines.exe"; p.Start(); p.WaitForExit(); string output = p.StandardOutput.ReadToEnd(); Because A deadlock condition can result if ...

Hi, I am wondering what happens in a program that just has a while(1); in the main() function when compiled with g++ on unix. When I run the program, I am seeing 0% cpu usage. Why is this? Shouldn't it hog up the cpu? Is the compiler optimizing this somehow? By putting a yield_processor like system call that context switches out? The ...

Sometimes after calling a function (which takes some 30 odd minutes to finish), you realize that you did something wrong and want to stop the program. How do you do that in MATLAB? What I do is shutdown MATLAB completely and restart. I think there would be a way to abort the execution of the function instead. Anybody know what that is...

System.Diagnostics.Process p = new Process(); p.StartInfo.UseShellExecute = false; p.StartInfo.RedirectStandardError = true; p.StartInfo.RedirectStandardOutput = true; p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden; p.StartInfo.Worki...
Please tell me the difference between a process group ID and a jobid. Is jobid a builtin of a shell program or is it related to the kernel? What are the uses of each of them? When a process is run in background, is only jobid set or is the pgid set as well? What are the uses of the setpgid() function? When a process is run in background...
I asked a related question 'Difference between process group id and job id in Unix', but I have a doubt that was not answered. In that answer, it was written that job id is built in data related to shell (kernel has nothing to do with it), so foreground / background is understanding of shell, but when we do "ps x" then it display in st...

I have a child process which has received a SIGTSTP signal. When I call waitpid(-1,NULL,0); the parent blocks, but in documentation, its written that waitpid returns with pid for stopped jobs. #include<unistd.h> #include<stdio.h> #include<signal.h> #include<sys/wait.h> main() { int pid; if( (pid=fork()) > 0) { sleep(5); if(ki...
