  • What environment variables available while starting the script using init.d boot process

    - by raj_arni
    My problem is like this (OS is Sun Solaris): 1) At the boot time I want to start a process using a specific script. I am doing this by putting this script in /etc/init.d (and following other K and S rules) 2) The program which will be called by the script is located at $HOME/xxx/yyy location. 4) I am using 'su - {myuser} -c "{full path of the program}"' in order to execute the script as {myuser} 3) I dont want to hardcode the value of $HOME in the script but want to use the $HOME env variable only. How can I get this $HOME env variable in the shell script? Also what other variables will be available to me?

  • Create File Speedily From Individual Column

    - by neversaint
    I have a data that looks like this: -1 1:-0.394668 2:-0.794872 3:-1 4:-0.871341 5:0.9365 6:0.75597 1 1:-0.463641 2:-0.897436 3:-1 4:-0.871341 5:0.44378 6:0.121824 1 1:-0.469432 2:-0.897436 3:-1 4:-0.871341 5:0.32668 6:0.302529 -1 1:-0.241547 2:-0.538462 3:-1 4:-0.871341 5:0.9994 6:0.987166 1 1:-0.757233 2:-0.948718 3:-1 4:-0.871341 5:-0.33904 6:0.915401 1 1:-0.167147 2:-0.589744 3:-1 4:-0.871341 5:0.95078 6:0.991566 The first column is class, and next 6 columns are features. I want to create 6 files for individual features. For example feat1_file.txt will contain -1 1:-0.394668 1 1:-0.463641 ... 1 1:-0.757233 1 1:-0.167147 feat2_file.txt will contain -1 2:-0.794872 ... 1 2:-0.589744 and so on. I have a Perl code that does this but it is horribly slow. Is there a way to do it faster? Typically the input files will contain 100K lines. use strict; use Data::Dumper; use Carp; my $input = $ARGV[0] || "myinput.txt"; my $INFILE_file_name = $input; # input file name open ( INFILE, '<', $INFILE_file_name ) or croak "$0 : failed to open input file $INFILE_file_name : $!\n"; my $out1 = $input."_feat_1.txt"; my $out2 = $input."_feat_2.txt"; my $out3 = $input."_feat_3.txt"; my $out4 = $input."_feat_4.txt"; my $out5 = $input."_feat_5.txt"; my $out6 = $input."_feat_6.txt"; unlink($out1); unlink($out2); unlink($out3); unlink($out4); unlink($out5); unlink($out6); print "$out1\n"; while ( <INFILE> ) { chomp; my @els = split(/\s+/,$_); my $lbl = $els[0]; my $OUTFILE1_file_name = $out1; # output file name open ( OUTFILE1, '>>', $OUTFILE1_file_name ) or croak "$0 : failed to open output file $OUTFILE1_file_name : $!\n"; print OUTFILE1 "$lbl $els[1]\n"; close ( OUTFILE1 ); # close output file my $OUTFILE2_file_name = $out2; # output file name open ( OUTFILE2, '>>', $OUTFILE2_file_name ) or croak "$0 : failed to open output file $OUTFILE2_file_name : $!\n"; print OUTFILE2 "$lbl $els[2]\n"; close ( OUTFILE2 ); # close output file # Etc.. until OUTFILE 6 } close (INFILE);

  • Basic HTML Internal Link not working in IE8

    - by Eamonn
    This one has me scratching my head. I have a page with several internal links bringing the user down the page to further content. Beneath various sections there are further internal links bringing the user back to the top. This works fine in all browsers apart from IE8 (actual IE8 - not IE9 in IE8 mode) where they work go down, but not coming back up! Examples: <a href="page.php?v=35&amp;u=admin-videos#a">A &ndash; General</a> .... //travelling DOWN the page <h3><strong>A &ndash; General<a name="a"></a></strong></h3> <a name="top"></a> .... //travelling back up <a href="page.php?v=35&amp;u=admin-videos#top">Back to top.</a> I've tried filling the 'top' anchor with &nbsp; but that hasn't changed it. Any ideas? Actual use case: http://databizsolutions.ie/contents/page.php?v=35&u=admin-videos

  • Need help with basic optimization problem

    - by ??iu
    I know little of optimization problems, so hopefully this will be didactic for me: rotors = [1, 2, 3, 4...] widgets = ['a', 'b', 'c', 'd' ...] assert len(rotors) == len(widgets) part_values = [ (1, 'a', 34), (1, 'b', 26), (1, 'c', 11), (1, 'd', 8), (2, 'a', 5), (2, 'b', 17), .... ] Given a fixed number of widgets and a fixed number of rotors, how can you get a series of widget-rotor pairs that maximizes the total value where each widget and rotor can only be used once?

  • Basic SWIG C++ use for Java

    - by duckworthd
    I've programmed a couple years in both C++ and Java, but I've finally come to a point where I need to bring a little unification between the two -- ideally, using SWIG. I've written a tiny and fairly pointless little class called Example: #include <stdio.h> class Example { public: Example(); ~Example(); int test(); }; #include "example.h" Example::Example() { printf("Example constructor called\n"); } Example::~Example() { printf("Example destructor called\n"); } int Example::test() { printf("Holy sh*t, I work!\n"); return 42; } And a corresponding interface file: /* File: example.i */ %module test %{ #include "example.h" %} %include "example.h" Now I have questions. Firstly, when I want to actually run SWIG initially, am I supposed to use the example_wrap.c (from swig -java example.i) or example_wrap.cxx (from swig -c++ example.i) file when recompiling with my original example.cpp? Or perhaps both? I tried both and the latter seemed most likely, but when I recompile as so: g++ example.cpp example_wrap.cxx -I/usr/lib/jvm/java-6-sun-.../include/ I get a host of errors regarding TcL of all things, asking me for the tcl.h header. I can't even wrap my mind around why it wants that much less needs it, and as such have found myself where I don't even know how to begin using SWIG.

  • How do I use Perl to parse the output of the sqlplus command?

    - by benjamin button
    I have an SQL file which will give me an output like below: 10|1 10|2 10|3 11|2 11|4 . . . I am using this in a Perl script like below: my @tmp_cycledef = `sqlplus -s $connstr \@DLCycleState.sql`; after this above statement, since @tmp_cycledef has all the output of the SQL query, I want to show the output as: 10 1,2,3 11 2,4 How could I do this using Perl?

  • Drupal Multisite - Subdirectory, Shared Hosting

    - by derekerdmann
    I'm trying to set up Drupal multisite in a shared hosting environment. The main site's location looks like http://www.mysite.com/foo/bar/ and my goal is to create another site using the same database at http://www.mysite.com/foo/bar/drupal2. I've created a new folder in the sites directory called www.mysite.com.foo.bar.drupal2 and added the default.settings.php and settings.php files, configured correctly for the environment, and I've set up a symlink from the main site's root to the subdirectory, with this command: ln -s . drupal2 The problem is that when I go to http://www.mysite.com/foo/bar/drupal2, I just get the main site at http://www.mysite.com without triggering the installer. What do I need to change to get the multisite working?

  • Help with basic php and xml needed

    - by Matt
    Hi, I'm really new to xml, with this being my first dip into it. I'm trying to add some text to an image using php and xml. I keep getting the following error: Parse error: syntax error, unexpected '}' in /home/a8744502/public_html/userbar.php on line 18 Below is my code. <?php header ("Content-type: image/jpeg"); $doc = new DOMDocument(); $doc->load( "http://phogue.net/feed/". LIBXML_DTDLOAD ); $procon = $doc->getElementsByTagName( "procon" ); $packages = $procon->getElementsByTagName( "package" ); $value = 0; foreach($packages as $package) { $downloadsA = $package->getElementsByTagName( "downloads" ); $downloads = $downloadsA->item(0)->nodeValue; $value = $downloads + $value } $font = "visitor1.tff"; $font = 4; $im = ImageCreateFromjpeg("procon_plugindeveloper.jpg"); $x = 360; $y = 0; $background_color = imagecolorallocate ($im, 255, 255, 255); $text_color = imagecolorallocate ($im, 255, 255, 255); imagestring ($im, $font, $x, $y, $value, $text_color); imagejpeg ($im); ?> The xml file is of the form <procon> -<packages> --<package> ---<downloads> ---</doanloads> --</package> --<package> ---<downloads> ---</doanloads> --</package> --<package> ---<downloads> ---</doanloads> --</package> -</packages> </procon> The idea is that it should print out the sum of all the downloads tags that are contained in . Any help is appreciated :-)

  • A basic animation not showing up

    - by Rilakkuma
    I still try different basics with android, and now I'm stuck with animation. I'm trying to implement a simple animation. I've defined animation in xml file like this: alpha android:interpolator="@android:anim/accelerate_interpolator" android:fromAlpha="0.0" android:toAlpha="1.0" duration="3000" repeatCount="infinite" In my main view group I have an ImageView defined like this: <ImageView android:id="@+id/someb" android:src="@drawable/earth_normal" android:layout_width="wrap_content" android:layout_height="wrap_content" android:padding="5dip"/> And this is from my starting activity class: public class Ohayou extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); ImageView earth = (ImageView)findViewById(R.id.someb); Animation earthFadeInAnimation = AnimationUtils.loadAnimation(this, R.anim.fade_in); earth.startAnimation(earthFadeInAnimation); } It finds ImageView successfuly and creates animation. but when I start emulator ImageView just shows the original src image, not an animation. What am I doing wrong? Thanks

  • Basic Python While loop compound conditional evaluation

    - by dbjohn
    In Python IDLE Shell it seems I cannot use a compound conditional expression and a while loop. I tried it within brackets too. k=0 m=0 while k<10 & m<10: print k k +=1 m+=1 If I write while k<10: print k k+=1 This does work. Is there a way I could achieve the first block of code with the "and" operator. I have done it in Java. Do I just need to put together "if" statements to achieve the same functionality in Python?

  • [jQuery] What would be the best way to perform a basic CRUD using AJAX

    - by rasouza
    I'm having trouble to make a simple CRUD in my site. I have a table of registries <table> <tbody> <?php foreach ($row as $reg) { ?> <tr <?php if ($reg['value'] < 0) { echo "class='error'"; } ?>> <td><?php echo $reg['creditor'] ?></td> <td><?php echo $reg['debtor'] ?></td> <td><?php echo $reg['reason'] ?></td> <td>R$ <?php echo number_format(abs($reg['value']), 2, ',', ' ')?></td> <td><a **href="<?php echo $this->baseUrl(); ?>/history/delete/id/<?php echo $reg['id']; ?>"** class="delete"><img src="http://192.168.0.102/libraries/css/blueprint/plugins/buttons/icons/cross.png" alt=""/></a></td> </tr> <?php } ?> </tbody> </table> which I would like to perform a simple delete in these rows using AJAX (preferenciably with jQuery). The question is: do I have to create a function in JS and add onmouseclick event in the HTML? is there a more consistent way for doing this, like adding $('.delete').click() directly in the js file? If so, how do I pass the row ID for the ajax function? What I really want is to know how to pass the row ID to $.ajax() jQuery function through a clean! way

  • appending text to all files that starts with a string

    - by learner135
    How do I append a string to all the files in a directory that starts with a particular string? I tried, cat mysig >> F* But instead of appending contents of mysig to all files starting with F, it creates a file named "F*". Obviously wildcard doesn't seem to work. Any alternatives? Thanks in advance. Edit: Also how do I delete this newly created file "F*" safely?. Using rm F* would delete all the files starting with F which I wouldn't want.

  • basic file input using C

    - by user1781966
    So im working on learning how to do file I/O, but the book I'm using is terrible at teaching how to receive input from a file. Below is is their example of how to receive input from a file, but it doesn't work. I have copied it word for word, and it should loop through a list of names until it reaches the end of the file( or so they say in the book), but it doesn't. In fact if I leave the while loop in there, it doesn't print anything. #include <stdio.h> #include <conio.h> int main() { char name[10]; FILE*pRead; pRead=fopen("test.txt", "r"); if (pRead==NULL) { printf("file cannot be opened"); }else printf("contents of test.txt"); fscanf(pRead,"%s",name); while(!feof(pRead)) { printf("%s\n",name); fscanf(pRead, "%s", name); } getch(); } Even online, every beginners tutorial I see does some variation of this, but I can't seem to get it to work even a little bit.

  • Django template tag basic question

    - by ninja123
    It looks like this template tag works like a charm for most people: http://blog.localkinegrinds.com/2007/09/06/digg-style-pagination-in-django/ For some reason I get this error: Caught an exception while rendering: 'is_paginated' I use this template tag in my template like so: {% load digg_paginator %} {% digg_paginator %} Where digg_paginator.py is in my app/templatetags folder and the included template context digg_paginator.html is in my app/templates folder. The queryset that needs pagination is called 'destinations'. If i just specify {% digg_paginator %}, how does it know what variable to paginate?? I feel I am missing something important here or just plain stupid :P Someone please help, or explain to me how this should be done. Thanks

  • Why do I get strange output from Perl using SQL?

I expected the pipes to be between the variables. Why are the pipes getting printed after all the three variables?

  • Shell script exiting the loop after calling another script

    - by Johnyy
    Hi Guys, I have a shell script s1 calling another script s2 in a loop. However s1 can not seem to continue the loop after s2 returns. Commenting out the line that calls s2 will enable the loop to continue. s2 does copy of one file, s1 checks conditions and copy several files using s2. Can anyone give a pointer what is going on here? ... while read line s2 param1 param2 param3 echo "copy done" done < $tempfile echo "out of loop" ... "copy done" is printed, so is "out of loop"
