  • Options for Linux OS executable archive files - self installers

    - by Matt1776
    I am looking to create a web-project that is able to install with a program. The user should be able to download an archive file or tar file, run it (executable), and the setup script would ask for paths and configurable values and then unpack its 'payload' and sorting out the contents for deployment. This would be a Linux version of the MSI installer. Is there such a thing for Linux operating systems? This does not involve kernel level manipulations. All it needs to do is copy directories and files on the filesystem, which should cover about 80% if not more of all the *nix distributions.

  • "Correct" way to playback user movement with xlib?

    - by Dasuraga
    I'm trying to figure out a way to make demos for a program I've written with xlib, and I came across this, but, according to the author page: This extension is not intended to support general journaling and playback of user actions. Does anyone know of any functions in xlib that are intended to support playback of user actions? Does it even exist? Or could I just use this without any real problems?

  • How to Sort ip addresses and merge two files in efficent manner using perl or *nix commands?

    - by berkay
    (*) This problem should be done in perl or any *nix commands. i'm working on a program and efficiency matters.The file1 consists ip addresses and some other data: index ipsrc portsrc ip dest port src 8 128.3.45.10 2122 169.182.111.161 80 (same ip src and dst) 9 128.3.45.10 2123 169.182.111.161 22 (same ip src and dst) 10 128.3.45.10 2124 169.182.111.161 80 (same ip src and dst) 19 128.3.45.128 62256 207.245.43.126 80 and other file2 looks like (file1 and file2 are in different order) 128.3.45.10 ioc-sea-lm 169.182.111.161 microsoft-ds 0 0 3 186 3 186 128.3.45.10 hypercube-lm 169.182.111.161 https 0 0 3 186 3 186 128.3.44.112 pay-per-view 148.184.171.6 netbios-ssn 0 0 3 186 3 186 128.3.45.12 cadabra-lm 148.184.171.6 microsoft-ds 0 0 3 186 3 186 1- SORT file1 using IP address in second column and SORT file2 using IP address in first column 2- Merge the 1st, 3rd and 5th columns of File1 with File 2 i need to create a new file which will look: 128.3.45.10 ioc-sea-lm 169.182.111.161 microsoft-ds 0 0 3 186 3 186 --> 2122 80 8 128.3.45.10 hypercube-lm 169.182.111.161 https 0 0 3 186 3 186 --> 2123 22 9 128.3.44.112 pay-per-view 148.184.171.6 netbios-ssn 0 0 3 186 3 186 --> * * * 128.3.45.12 cadabra-lm 148.184.171.6 microsoft-ds 0 0 3 186 3 186 --> * * * basically port numbers and index number will be added.

  • Is there a POSIX syscall to resolve file system paths?

    - by Mike
    Is there a POSIX syscall to resolve filesystem paths? I have the CWD for a path, as well as the path to a file from that CWD. I can't use chdir to switch to the directory because I need to resolve paths from multiple threads simultaneously. I considered appending a / in between the CWD and the path, but for some reason it feels like that's hacky. Is that the proper way to resolve relative paths?

  • Gems install fine but don't show as installed under rake gems

    - by Josh Pinter
    I'll show you my output here: rake gems (in /Users/jp/Sites/central/trunk) - [F] authlogic - [R] activesupport - [F] builder - [F] formtastic - [R] activesupport >= 2.3.0 - [R] actionpack >= 2.3.0 - [ ] fastercsv I = Installed F = Frozen R = Framework (loaded before rails starts) Making sure fastercsv is installed: gem which fastercsv /usr/local/lib/ruby/gems/1.8/gems/fastercsv-1.5.3/lib/fastercsv.rb After installing through a variety of methods but only one is shown here: sudo rake gems:install (in /Users/jp/central/trunk) gem install fastercsv Successfully installed fastercsv-1.5.3 1 gem installed Installing ri documentation for fastercsv-1.5.3... Installing RDoc documentation for fastercsv-1.5.3... And try it again. rake gems (in /Users/jp/Sites/central/trunk) - [F] authlogic - [R] activesupport - [F] builder - [F] formtastic - [R] activesupport >= 2.3.0 - [R] actionpack >= 2.3.0 - [ ] fastercsv I = Installed F = Frozen R = Framework (loaded before rails starts) One thing to know is that I tried unpacking the gems but if it doesn't think it's installed it can't unpack it. Another thing is that I really tried to figure this out. There's a bunch of people saying clean up local gems in your user account, always install with sudo, etc. But I've tried all that. What would you guys do to fix this? Thanks many times over, Josh

  • elegant way to make directory recursively in Python?

    - by user248237
    I would like to make a directory in a "recursive" way, i.e. have a function make_directory() that behaves as follows: make_directory("a/b/c/d/") should create directory a, then child b, then c, then d. If any of the parent directories exist it should not make them. E.g. if "a" exists, then b should be a subdir of that, and then c should be made inside b, etc. how can I do this in python? os.mkdir does not have this behavior.

  • Inserting text to a file with Sed within Bash Script

    - by neversaint
    I tried to insert a text to the first line of a file using sed. I do this inside a bash script. But why it hangs at the line of sed execution? #! /bin/bash # Command to execute # ./mybashcode.sh test.nbq nbqfile=$1 nbqbase=$(basename $nbqfile nbq) taglistfiletemp="${nbqbase}taglist_temp" taglistfile="${nbqbase}taglist" ./myccode $nbqfile | sort | uniq -c | awk '{print $2}' > $taglistfiletemp noftags=$(wc -l $taglistfiletemp | awk '{print $1}') echo $noftags # We want to append output of noftags # to the first line of taglistfile sed '1i\ $noftags' > $taglistfile # why it hangs here # the content of taglistfile is NIL

  • Renaming and Moving Files in Bash

    - by KT
    HI, I'm completely new to Bash and StackOverflow. I need to move a set of files (all contained in the same folder) to a target folder where files with the same name could already exist. In case a specific file exists, I need to rename the file before moving it, by appending for example an incremental integer to the file name. The extensions should be preserved. The file names could contain dots in the middle. Originally, I was thinking about comparing the two folders to have a list of the existing files (I did this with "comm"), but then I got a bit stuck. I think I'm just trying to do things in the most complicated possible way. Any hint to do this in the "bash way"?

  • AWK If/ElseConditional Problem

    - by neversaint
    I have a data that looks like this: foo foo scaffold_7 1 4845 6422 4845 bar bar scaffold_7 -1 14689 16310 16310 What I want to do is to process the above lines where I just want to print column 1,2,3, 7 and one more column after 7th. But with condition when printing column 7 onwards. Below is my awk script: awk '{ if ($4=="+") { {end=$6-$5}{print $1 "\t" $2 "\t" $3 "\t" $4 "\t" $7 "\t" end+$7} } else {end=$6-$5}{print $1 "\t" $2 "\t" $3 "\t" $4 "\t" $7-end "\t" $7} }' But why it doesn't achieve the desired result like this? foo foo scaffold_7 1 4845 6422 bar bar scaffold_7 -1 14689 16310 Note that the arithmetic (e.g. $7-end or end+$7) is a must. So we can't just swap column from input file. Furthermore this AWK will be inside a bash script.

  • Detect number of IDLE processors ruby

    - by Yannick Wurm
    Hello, I work on shared linux machines with between 4 and 24 cores. To make best use of them, I use the following code to detect the number of processors from my ruby scripts: return `cat /proc/cpuinfo | grep processor | wc -l`.to_i (perhaps there is a pure-ruby way of doing this?) But sometimes a colleague is using six or eight of the 24 cores. (as seen via top). How can I get an estimate of the number of currently unused processors that I can use without making anyone upset? Thanks!

  • Erlang programming exercises

    - by valya
    I'm learning Erlang. I've moved from Haskell so I don't want to and have to learn functional programming. But Erlang is quite specific because of the microprocesses. So, can you give me some examples which will be simple to test and measure and use all the power of Erlang?

  • Signal processing or algorithmic programming for a PLC

    - by james singen smythe
    I have an application that takes voltages and temperatures as analog inputs and does some processing using an algorithm which involves signal processing such as low-pass filtering, exponential smoothing, and other steps which might typically be done in a high-level programming language such as C or C++. I'm curious how I could perform these same steps using a PLC, and in particular, the Allen-Bradley Control-Logix system? It seems to me that the instruction set with ladder logic is too limited for this. Could I perform this using structured text?

  • Is it possible to view the "source" for a ksh function?

    - by stevec
    Our ksh environment defines several functions, which can be listed using then "functions" ksh function. Is it possible to see the definition (ie source code) for these functions? This seems like an obvious question, but I've tried all manner of parameters to the "functions" and "function" functions with no luck. Thanks, Steve

  • Apache is running but there is no page displayed

    - by Michael Ozeryansky
    I am on a Mac OSX and I am using the built in PHP and Apache2. I have been setting up MySQL and finally when I got MySQL working my local site won't display. Do note that I did have the web server running and delivering PHP enabled pages, just no database connection. But my question is not about MySQL. I have changed various settings in the 'http.conf' file, and I have the line: '127.0.0.1 localhost' in my hosts file. I also have other alias' pointing to 127.0.0.1. I have checked everything I could about Apache and I have made sure that any message in the error_log is ok. I currently have my errorLevel set to debug, so I get all the messages. At this point (HOURS of self fixing) I think I need help. What can I provide for someone to figure this out with me. Thanks.
