Ubuntu :: Super Basic Shell Script - Cannot Get Return Line
Jan 24, 2011I'm trying to create a super simple shell script, but I cant get a return line. The shell script looks like this (only the part that matters)
Code:
yes '' | ssh-keygen
The idea being it will put in a blank char. Then enter until the program finishes. The problem is, it only does the first time, the next 2 times I have to hit enter, it requires me to input it manually (which is exactly what I'm trying to avoid).
The full script (if you care):
Code:
#!/bin/sh
# Created by Omega
# First, program creates RSA key, named id_rsa and id_rsa.pub
# Second, program send the public code to requsted server.
echo 'Removing old id_rsa key (if applicable)'
rm -rf ~/.ssh/id_rsa.pub
rm -rf ~/.ssh/id_rsa
echo "Creating RSA key"
yes '' | ssh-keygen
# Checking if ssh-kkeygen created requested file
if [ -e ~/.ssh/id_rsa.pub ]
then
echo 'Done'
echo 'Username and Server in: me@server format'
read var1
echo 'Port Number? If standard put 22'
read var2
ssh-copy-id -i ~/.ssh/id_rsa.pub "-p $var2 $var"
else
echo ''
echo 'ERROR, ssh-keygen did not execute correctly'
echo 'Retrying...'
echo ''
echo 'Please leave all options default (just press enter)'
ssh-keygen
if [ -e ~/.ssh/id_rsa.pub ]
then
echo 'Done'
echo 'Username and Server in: me@server format'
read var1
echo 'Port Number? If standard put 22'
read var2
ssh-copy-id -i ~/.ssh/id_rsa.pub "-p $var2 $var1"
else
echo 'ERROR, ssh-keygen did not execute correctly'
echo 'Quitting'
exit
fi
fi

Programming :: How To Bind Thread To Specific Thread In Multithread Application?
Dec 25, 2010I am going to use "pthread_setaffinity_np" to bind a thread to a specific core. My application has two threads. I have used mutex to assign a specific id to each thread and then bind that thread to a core different from another core. but it seems that the os assigns both thread to one core.What should I do to bind each thread to a specific core?

Jun 5, 2011how to use the <Super>ButtonX (<Super>Button1 for example for the enabled Compiz Screenshot plugin)? I also notice there is configurable buttons 1 throught 20 under the various options. At first I thought the ButtonX was a mouse button. Maybe it is with some anticipation of there being eventually being a possible 20 buttons on the mouse. I know the Super key is the Key with the Windows logo on it. But I don't know what to do to get the needed Super Key / Button combination. After having enabled Compiz's Screenshot plugin by its default, I don't get an image after hitting any of the Super key and mouse button combinations. I'm running Ubuntu 11.04.

View 2 Replies View RelatedProgramming :: Determine What CPU Thread Is On?
Jul 2, 2010Is there a library/system call that will return to me what CPU core a thread of execution is running on? I've looked for a bit on the net already and also in /usr/include and couldn't find one.
getcpu() and sched_getcpu() are two that I found, but when I include the appropriate header files (linux/getcpu.h, and sys/sched.h respectively), gcc says getcpu.h doesn't exist and the linker complains it cannot find the implementation in sched.h.
I'm sure I'm doing something really stupid or overthinking...
What I am doing is running an OpenMP application and specifying a list of cpu cores to run on with GOMP_CPU_AFFINITY. I want to make sure that each core is getting the same number of threads.
**UPDATE**
It seems that this code works, but only with glibc >= 2.6, and my machine has 2.5:
Code:
#define _GNU_SOURCE
#include <stdio.h>
#include <utmpx.h>
int main( void )

Fedora :: Super / Win Key Is Not Working
Oct 8, 2009I just installed Fedora 11 on my PC and can't seem to get the Win key to work at all I tried putting entries in xmodmap, tried modifying xorg.conf, and also tried setting altwin:super_win in the config settings. But nothing seems to work. Somehow, my Win key seems to be working as Meta instead of Super. From emacs, if I press Win+x, it works like Meta+x.

Ubuntu :: When Does The POSIX Thread Start
Feb 3, 2010i'm trying to understand the POSIX threads and i can't understand when does the thread start: does it start when i do
pthread_create()
or when i do
pthread_join()
or maybe i'm missing something. i do understand that pthread_join() causes the calling thread to wait till the called thread is finished.

Feb 10, 2011i know i should look more through the forum, but i've been stuck on installing ubuntu on my computer for 3 days now, reinstalling, manual grub installing and so on, but no go. but i found a good thread on my still no fully functional ubuntu computer that explained very well for a complete linux noob how to install grub2 on ubuntu via the livecd. but since i was booting from the live cd meant that i couldn't bookmark it, and very little on this forum, as far as i can see, gets sticky, makes it very hard to find.
the basic problem is, i completly reinstalled ubuntu 10.10, and the bootloader (that i now know is named grub2) could not be installed. so i've found several guides, including the wiki, but it haven't really worked. now instead of explaining all of this over again, like all of you have probably done a million times, can you just post the most informative links here, so i can pick and choose,

Programming :: Thread Scheduling And Signalling
Mar 23, 2010I have a program which is uses sigaction to register for a SIGIO signal (for incoming data on a fd) with an appropriate event handler. I also create a new detached thread 'B' that does some work with the received data. Normally the thread B runs properly. But when my event handler is called (because a there is new incoming data), after the event is handled, the thread B is not called immediately. There is a noticeable delay of the order of many seconds before it is scheduled again .During this delay, my program is doing nothing.
What am i doing wrong? Is there someway i can run thread B as soon as the event is handled (and assuming no other work is to be carried out)?

Programming :: Thread Stack Using Pthread_attr_setstackaddr()?
Sep 22, 2010When I set the stack base address of the child thread using the POSIX library function "pthread_attr_setstackaddr()", I am unable to access the memory contents of its parent. The data-structures that are created on the HEAP of its parent using malloc() are either getting destroyed or unaccessible when moving to the context of the child thread. These data-structures are being passed as an argument to the child thread.Even if I make these variables global then also it is not working.pthread_attr_setstacksize(tattr, ...);stackbase = (void *) malloc(...);pthread_attr_setstackaddr(tattr, stackbase);But when I create the child thread without setting its stack base address using that pthread_attr_setstackaddr(), then it is able to access the parent's memory contents.
