General :: What Is Great Book To Start Learning Scripting In Bash?
Apr 23, 2010I've been switched to a new department at work and am totally clueless when it comes to scripting in bash. When I told them I was a fast learner, I didn't think they'd throw me into the deep end of the pool so fast. So to make a long story short. What is a great book to start learning scripting in bash? My supervisor already gave me a simple task to do. Conceptually it sounds quite easy in my head, but actually writing out a script is a bit more daunting and complexed than I first thought.

I am in the data storage industry and have a good basic understanding of unix and linux. For my own learning I want to start learning some basic scripting where I can create simple things that make life easier like to become a beginer UNIX or linux admin..what should i start with...I just seem to be so overwhelmed cause there are some many things you dive into..I see so many types of scripting shells I don't know where I should start to learn the basics
View 4 Replies View RelatedUbuntu :: Pointers To Learning Scripting?
Apr 25, 2011I have a project for my computer class, and I was a bit ambitious with my ideas and am wondering if I made a smart choice. I need to learn sooner or later anyway! I'm a beginner when it comes to scripting but I'd like to learn more advanced stuff. When I say basic I really mean basic among all basic. To give you an idea I only know some simple HTML and Python. The idea I proposed for my project goes as follows:
The challenge we were given is to create a spreadsheet of data from a website given to us. Points are given for creativity and simplicity in how we go about doing this.After taking a look at the site (or rather, html files given to us), and with having dabbled with Python before, I came up with what I thought was a pretty good idea.The pages of the "site" are just numbers. They go from 001-117 .html in terms of filenames. Their source code has some sort of table set up, and the information we are pulling off are easily found by the tags that precede them (the info, btw are the periodic elements).
The tags are pretty obvious, and state pretty much what they are labeling. My python knowledge is almost nonexistent but I figured that would be something Python would be capable of. Why do I post this here? I'm relatively new to Ubuntu too but keep hearing about bash scripts and such. Would this be even better? (Perhaps it's silly but I'd like to use Ubuntu to accomplish this)
Or is there an even better scripting method/language I should be using? Could anyone give me some pointers in how I could accomplish this? I'm really hoping to learn a lot from my first "real" scripting experience!

Mar 19, 2011I'm looking for the most pure linux terminal distro. I am trying to learn linux and I have Ubunutu 10.10 installed but I feel like it's not as pure as other distros, like Ubuntu 10.10 is different from the average terminal experience.
Maybe I am wrong about this, but certain things like the grub .lst file is now a .cfg file in Ubuntu, is this replicated across all linux, or is this unique to Ubuntu? Little things like this that make it difficult to learn. Are all the distros unique in this way?

Oct 28, 2010I'm cross-posting in order to get as a wider audience to get as much feedback as possible. I am currently studying to learn the ) Gidhlig (Scottish Gaelic language and finding studying by rote out of a book a bit 'limiting'. Because of this, I am thinking about creating a software project which could act as an interactive way to helping me learn the language. I've got a few ideas floating in my head but the direction I want to take is that the software is not an alternative but an aid to be used in conjunction with traditional studying materials. I was thinking possibly small interactive games or exercises that both are fun as well as to test and use the parts of language I have learned. There might also be a bit of reporting to show strengths and weaknesses.
Firstly, the technical specifications, that offhand, I can think of that the project will need to meet:
1. Cross-platform (while I would like it to be just Linux, I have to be realistic that people would rather use Windows)
2. The language data is separate from main program so that the software can be used with other languages.
3. Not too complex so that it is quick and easy to program as I will be doing it myself.........
General :: Distro Better For LEARNING Security Skills?
Jun 27, 2010I currently run Ubuntu 10.04 alongside Vista. I have been looking for a few linux projects to help me learn, the two that I have thought of have been:
1. LFS
2. Something security related
As for no.2, I am interested in learning about network security, intrusion detection, system logging, firewall logging etc. And as a project I would like to work on creating a desktop box as secure as possible, then maybe testing my own box on my home network.
1. Is there a good linux distro that is designed for security?I know people often say "the distro doesn't matter, it only matters how you configure it.
2. Does everyone agree with this? As far as security, learning, etc, are all distros created equally?

Mar 13, 2010I am starting a project of my own (and learning C++ at the same time. I got my program to successfully scan a custom netmask, but it is REALLY slow. I want my program to do something similar to nmap -sP xxx.xxx.xxx.xxx-xxx. How to speed it up? Such as pinging more than one IP at a time...
Code:
#include <iostream>
#include <cstdio>
#include <cstdlib>
#include <sstream>
using namespace std;
int ip42;
string ip1, ip2, ip3, ip4, ipaddr;
int main() {
cout << endl << "Enter part 1: ";
cin >> ip1;
cout << endl << "Enter part 2: ";
cin >> ip2;
cout << endl << "Enter part 3: ";
cin >> ip3;
cout << endl << "Enter part 4: ";
cin >> ip4;
while(ip42 < 255){
ipaddr = string("ping -c 1 ").append(ip1);
ipaddr = string(ipaddr).append(ip2);
ipaddr = string(ipaddr).append(ip3);

Programming :: Experience To Make A Script More Efficient?
Mar 30, 2010I wrote this script to attach url's to specified 6 digit numbers in a configuration text file. My original goal was to be able to be able to pull the url's and the 6 digit numbers from .csv files. that would allow me to make the script more versatile, not only for this particular project, but also for other projects in regards to the configuration file. This script works, and has served it's purpose, but it is not very pretty, and it's probably not very efficient. What can I do to improve it and possibly make it more versatile. I've thought about functions and arrays, but my skill set is still pretty limited. I'm not looking for someone to write it for me, just to point me in the right direction.

Ubuntu Networking :: Setup The Most Efficient Way To Remotely Administer A System?
Aug 7, 2010I am trying to setup the most efficient way to remotely administer an ubuntu system. So far I was successful in setting up ssh. I have the server running and made sure it only uses keys to authenticate and changed the default port. I can connect to the ssh-server. This system is behind nat and bots trying to break-in when I forwarded the port. I used the AllowUsers option, which helped in knocking back these rouge connections. I was not comfortable leaving a port open all the time, so I set up logmein Hamachi VPN and closed the ports that were open on NAT.
Now I use Hamachi and am very impressed. I use VNC in VPN. But Vino is slow, I tested x11vnc and it was slightly faster. I also tried to set up freenx but nxsetup file was missing. some one posted that file in the forums and suggested copying to the system but I was not sure if I want to download a script from the forum and use it. So for the time being, I thought I will just concentrate on X11vnc until freenx is fixed.
I would like to create a separate desktop on the server and use it to access remotely. This way we will not have to fight over the cursor (sounds funny but very frustrating). From what I understand x11vnc has this function inbuilt (uses vncserver). I cannot get it to work! when using ssh, at the remote machine's command prompt, if I type "evince xyz.pdf", it does not launch the "xyz.pdf". what am I doing wrong? When using VNC, how can I change between different users on the remote machines? Right now I can only use VNC in one account that I first setup. When I try to change to another user, vnc client goes blank. How can I get as much control of the remote system as possible? Right now I need someone to switch on the remote system and login to their account before I can VNC. Can I use ekiga inside VPN, I use skype right now and it's sometimes terrible with dropouts. I looked around and someone suggested using ekiga as it works very well over lan. How do set up ekiga so that I have a direct connection with the remote system? Is there any client that just takes the IP address and creates a connection? Mumble seems to be the popular choice, it's most suited to LANparties, I just need a connection between two systems. I am trying to set this up to help users with hardly any computer knowledge to use the system without any issues.
Programming :: Efficient Access Of Huge Files Or Defrag Ext4?
Sep 30, 2010I need to figure out how to arrange for the fastest-possible read-access of a large or huge memory-mapped file. I'm writing high-speed real-time object-chasing software for a NASA telescope (on earth). This software must detect images of fast moving objects (across arbitrary fields of fixed stars), estimate what direction and speed the object image is traveling (based on the length and direction of a streak on the detection image), then chase after the object while capturing new 4Kx4K pixel images every 2~5 seconds, quickly matching its speed and trajectory, then continue to track and capture images until the object vanishes (below horizon, into earth shadow, etc).
I have created two star "catalogs". Both contain the same 1+ billion stars (and other objects), but one is a "master catalog" that contains all known information about each object (128 bytes per object == 143GB) while the other is a "nightly build" that only contains the information necessary to perform the real-time process (32 bytes per object == 36GB) with object positions precisely updated for precession and proper-motion each night. Almost always the information in the "nightly build" catalog will be sufficient for the high-speed (real-time) processes.
