I have 3 scripts that need to be run from the cd, I can run them separately but thought it would be easier to just call them from a single script.When I run the script it just goes straight to reboot, which is the last command. Can you see what I am doing wrong? I am logged in as root when I execute it.
View 3 RepliesIn practice I have a script that call a java program that call a linux system command. The script if I run it, from a shell functions well,so it is not a java problem. The problem come out when i put this script in a crontab schedulation. The result in this case is that java do not execute the system command. I think it depends on crontab

View 1 Replies View RelatedI am writing a shell script lets say run.sh and i want to call another script lets say test.sh having permissions " root:sys" whereas the permissions for run.sh are "rootther".Problem is that i cannot change the permissions of either of them. run.sh is performing some other important functions as well and test.sh is a system script and i am not supposed to change that.If i do not change the permissions, run.sh simply skips the part where it is suppose to call test.sh.Can anyone tell me how do i call test.sh in run.sh without changing permissions of any of them.

Back in the day (maybe as recently as kernel 2.4?) this used to work. Memory-hungry processes would be killed by the oom killer and I would restart them. But now (Linux 2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:24 UTC 2011 x86_64) google-chrome (13.0.782.24 beta) regularly sends my machine into a death-spiral of swapping. Or at least something that feels like swapping: X windows take forever to update, disk drive whirs, gnome panel memory chart hits the ceiling, and I see this message in the syslog:
[Code]...
But, according to syslog, the kernel does not run the oom killer. For good measure, I set swappiness to 0:

My workaround is to use ctrl-alt-sysrq-f when this starts to happen. Anyone have a recipe for configuring Linux to run oom_kill on its own, in this situation?
I can find all kinds of information on calling a script from a makefile but not the other way around.I'm writing a VERY basic shell script, and I need to call a makefile located in a directory lower than the shell script but can't seem to figure it out../dir/make and ./dir/makefile don't work.
View 2 Replies View RelatedHere is a test code for memory alloc and free. It is to detect whether the allocs and frees match. From the result, after backtrace call, there is some memory alloc, but it does not free these memories after calling or the process exit. Why? Nomorlly, the memory alloced need to be freed after use, or the memory will leak. But I run this program for about some times, and find that though the system memory does not real leak,the free memory decreases, and the cache increases(Use free command).

I am searching for any system call similar to "ls" command we use in shell. My requirement is knowing the files and directories in curent working directory and process them based on there type. Here as of now I spawn another procees with system command like system
("sh ls -l | grep ^d | awk '{print $9}'").
Instead of this I want to use any system command where I can capture this information directly into my local character buffer. My opinion is that system calls will not spawn another process as a result less time it takes, another reason is once I use the system command again I need to capture the information to a local file then again read it into local buffer. I want to avoid the file manipulation here.

I have code in several places that calls

successfully. I need to put it into a new place in a application running on the system. When I do, it seems to just lock up the system and does not return from the call nor leave me able to Telnet in or Ping or anything. I've tried puttingtrace code in to write info out to a file, but that too is not working (as it never returns from the reboot() call.I don't get any error from reboot(), it just does not return and does not appear to restart the system.
