I have a folder of 2 many files that the old ls just hangs.
I am trying to write some log files such as;
I don't mind doing one at a time, but I am just playing and even getting the listing I am not getting the date stamp, I have the following;
That does create the file, but all the files look like this;
So basically it's just sticking that ls inside the log file and not actually running the ls, so how can I use the above type to get files just created per year?
I am trying to write a simple client that opens a secure connection. My intent is to use the OpenSSL library.
I am following this tutorial: [URL]... The tutorial mentions that I need a trust certificate store called TrustStore.pem. However, I can't find that on my machine. Is there a way to generate it? I separately downloaded the source from the OpenSSL website. The source distribution doesn't have it either. There is a whole bunch of .pem files. Can I use any one of them?
wants to do miniproject as part of the academic curriculum using Computer graphics on Linux using C or C++. Can any one direct me to a direction how i can proceed. I know basics of C and C++
View 9 Replies View RelatedWell I have been interested in programming for a while, and just found out about Linux and Unix. I started out with Java, but now I know I bunch: Flash, C++, C and others. I was working on a mac so I made a few flash games then started to work on iPhone games. I was board one day and I found out about Unix and I thought that would be something else to try.So in an attempt to learn about Unix I have been reading different articles about it, and have heard of using different languages in one program. The article I was reading didn't give any examples, and it assumed the reader has programmed Unix before.
So how do you write programs in multiple languages, which languages would you use, and why would you want to do that?
I printed Bruce Eckel's book "Thinking in Java" and Bjarne Stroustrup's book "Programming Principles and Practice Using C++". They are just great.I installed Fedora 14 with java development features including Eclipse IDE.Now I want to be able to recreate the examples from the books and experiment over them in Eclipse.I have been working for a while with python and django merely in the terminal and gedit without Eclipse.Please, help me to get started. How can I write my Java or C++ programs as projects in Eclipse?

2) Open the Hexter softsynth and make the Jack connections between it and my speakers;
3) Make the Jack MIDI connection between my MIDI keyboard and Hexter.
Do you know how to write programs that use electronic signatures in JAVA (although I am not pretentious about the language in any way).
When I say e-signatures I mean those USB smart cards(security tokens) that are capable of doing encryption by themselves and store securely the private key. I am particularly interested in how authentication works with a digital signature, how to sign data, and most importantly how to check that a digital certificate is valid. What do I need to store in the Database for authentication for example -- is it the serial or the Hash?

View 8 Replies View RelatedAssistance in choosing a no frills rolling Linux Distro. Over the past few months have gotten my feet wet with Mepis, Linux Mint, Ubuntu and other distros. I really like these Linux distros. However, I dislike the need to frequently "reinstall" a distro as often as every 6 months just to keep it updated.
My computer:
PC with 1.4 GHz Athlon
512 RAM
320 Gig hard drive partitioned equally between Windows XP and a Linux Distro.
My computer is used primarily as a jukebox connected to my stereo system, and for email, browsing, etc. I am not a gamer.I'm tired of Windows and its problems; malware, viruses, and currently if I upgrade to Windows 7, I'll need a new computer just to meet the hardware requirements when what I have works for my needs, but the XP operating system is becoming obsolete.
I am looking for a distro with an extremely simple desktop interface. I am looking for something as simple as the iPad where you can only run 1 application and it gets maximized. You click an icon and... you get that. Also the hardware is well described as "Aging," it is not dual-core, and may be as low as 64mb of RAM.
This is because the computer will basically be used as a simple game machine, and by game I mean Minesweeper and Solitaire. For Multiplayer games maybe virtual board games on a single screen, no LAN type stuff. Also I do not want the primary users of this computer to be able to access anything besides exactly what I determine they are supposed to. Basically what we want is something that is Child-Safe and Child-Simple. There will be no internet browsing or document creation or anything complicated.
Now I am not saying however that there won't be a possible user login that does have access to a full complement of software programs, just that I need to be able to setup at least one login that meets the criteria I specified. I have used Ubuntu in a few iterations, I can use a terminal with some internet help, and consider myself "Technical." Primarily I will be managing the software.
how (or what to use) to build a simple GUI on an embedded Linux system? I am using the Linux distribution Angstrom with a gcc compiler, and need to draw graphics on the screen. Preferably NOT in X11, but in a console only image. Are there simple graphics commands in C that will draw circles, boxes, and lines?
View 1 Replies View RelatedI'm a low-demand home desktop user concerned mainly with OS stability and simplicity. Current setup is dual-boot PC with Ubuntu10.04+Mint9. I use my PC mainly to write, using Word on Wine. Even more boring: I connect to net via external dialup modem. Both Ubuntu10.04+Mint9 seem excellent but have tons of features I don't need.
Is there a distro that will trade off advanced features in exchange for stability and reliability? I've read that Mepis is among the most rock-stable distros, with no attempts to be cutting-edge. Is this the case? Is there another distro emphasizing stability and simplicity? Must be a simple install, like Ubuntu+Mint. Must work well with Wine and dialup.
I have written this simple script to delete files and keep a log i have put this script in crond job
The script check the test directory in /home/francis if it encounters a file which is a 30 days old it must delete that file and place the file deleted in mylogs as a log report the script works fine i manually i have two problems:
First when the script ram the first time it generated the log of the files it deleted but the next day when i came it deleted the file but no log was generated
Secondly i run the script every day at 9 am this is the entry made in crond file * 9 * * * ~path to file but it seems to run every minute i even triedseperating the fields by tabs still the same

View 2 Replies View RelatedI've mounted a share using standard nomenclature for the NFS mount command with the following command line:
mount -t nfs -o rw {IP address1}:/ /mnt_for_70 / {IP address2}(rw)
mnt_for_70 is a mount point I created on {IP address2}
I'm confuse and want to be sure I use the correct command on the correct host to correctly umount the nfs share.
Would I execute umount /mnt_for_70 on {IP address2}
Not sure if such a simple command will work. As this is a semi-production host pair, I hesitate to just umount so simply & I have no test systems to try this on...
I need to download a particular NNTP group. I do not need to setup any crons, put group contents in /opt and other stuff. Just run <fetch-nntp> <server> <group-name> <output-dir> and be done with it without putting a lot of garbage in the system.
If that <fetch-nntp> would not fetch the same messages on the second run fine. But I can live without it. All NNTP clients that I've looked at are trying to be a NNTP server as well. Is there something simpler that is suitable for my needs?
