If a process is killed with SIGKILL, will the changes it has made to a memory-mapped file be flushed to disk? I assume that if the OS ensures a memory-mapped file is flushed to disk when the process is killed via SIGKILL, then it will also do so with other terminating signals (SIGABRT, SIGSEGV, etc...). ...
I have two commands I execute frequently. Let's say the first is 'abcd' and the second is 'abc'. So my history contains 1000 abc arg1 arg2 arg3 1001 abcd arg1 arg2 arg3 Now if I type '!abcd' in bash, it executes the abcd command. which is fine. But if I type '!abc' in bash, it also executes the last abcd command (since it matches the...
Hi, I am doing a find and then getting a list of files. how do I pipe it to another utility like cat (so that cat displays the contents of all those files) and basically need to grep something from these files. ...
I've got three files on AIX that I need to import into a SQL Server 2005 database. The files are created by an AIX script that I have control over. There are several options that I know will work, but I'd like to find out what others have done before and what works best. Here are the options I'm looking at. Have the AIX script sftp th...
I am deploying a large set of perl/shell/sql code on AIX. these could be (and are) different applications with their own dev teams, source control repos, etc. I am lazy and want to make deployments/roll-backs easier - and I am digging towards rpm packaging with all it's +/- benefits. AIX native system of packaging is installp (with bf...
The responses to my previous question suggested SSIS as the most efficient and reliable way to get files from AIX into SQL Server. I agree that it's probably a good idea. But for the sake of understanding the other options better, I'd like to narrow the scope a little bit. Irrespective of what I plan to do with the files, how can I dete...
I have a server that listens for socket connections and perform different kind of actions, depending on the request. One of them is long lived database queries, for which the server forks. The server keeps a log of all the active children and whenever asked to shutdown, it will kill all it's children before exiting. A couple of times I ...
Interested in something similar to JavaScript setTimeout in C on both UNIX and Windows. Basically, I want: start_timer(&function_pointer, int time_in_secs) or as close to that as I can get. Also, something similar to setInterval would be nice (where it calls the callback every n seconds), but that can be implemented using setTimeout...

For example on windows there is MsgWaitForMultipleObjects that lets you asynchronously wait for windows messages, socket events, asynchronous io (IOCompletionRoutine), AND mutex handles. On Unix you have select/poll that gives you everything except possibility to break out when some pthread_mutex is unlocked. The story: I have applica...
I'm reading/writing data off of a named pipe. On the writing side it says that it's writing a constant 110 bytes. On the Reading side for the majority of time it says that it's reading 110 bytes which is correct, but other times it says its reading 220 bytes or 330 bytes. Which is right in the fact that when I print it out it's printing ...

A colleague of mine asked me to write a homework for him. Although this wasn’t too ethical I did it, I plead guilty. This is how the problem goes: Write a program in C where the sequence 12 + 22 + ... + n2 is calculated. Assume that n is multiple of p and p is the number of threads. This is what I wrote: #include <pthread.h> #include <...
