Programming :: Get Variable Values From Keyboard?

Jul 11, 2010

I have been reading the Wikibook on C Programming for quite some time and am up to the variable part. I did learn several new things, like that too many variables hog memory.

What I want to know is how to assign a variable to the keyboard (in the C/C++ family) as such that the user has to type it in.

Programming :: Fork() - Variable Values Between Child And Parent Process?

Feb 24, 2010

Code:

int main()
{
int pi;
int i=10;
pid=fork();

[code]....

Q 1. The value of the variable pid returned by the fork() function will be greater than 0 in the parent process and equal to zero in the child process? but during forking, there values are exactly copied so what's went wrong here?

Q 2. "changes to the variable in one process is not reflected in the other process" why it is so? >> Even if we have variable i declared as a pointer or a global it wont make a difference.

Code:

int main()
{
int i, pid;
i=10;
printf("before fork i is %d

[code]....

Q. Through this program it is clear that both process is using the data from the same location, so where's the original value is residing when the child process is in execution.?

Programming :: Invoke Methods Via Ssh On Servers From CSV?

Jan 14, 2011

I have to execute certain commands (like shutdown Tomcat) on several servers so I'm using a loop and ssh. I put the server's IP on a CSV file which I parse, execute the commands for each line and send the output to a file. The problem is that after processing one line the program stops execution. I wonder if someone could lend me a hand with this, I'm new in bash scripting and I ran out of ideas.

The CSV (servers.csv) file looks like this:

Code:

192.168.254.5:Server 1
192.168.254.6:Server 2
...

And the script looks like this:

Code:

#!/bin/bash
while IFS=: read ip name
do
sshpass -p "pass" ssh -o "StrictHostKeyChecking no" root@"$ip" 'sh <CATALINA_BASE>/bin/shutdown.sh' >> output.log
done < servers.csv

Programming :: Invoke Cairo Functions From Glade?

Feb 12, 2011

I have created a glade file which so far have two regions in it:

1) On the right division is a toggle button which calls a C script when enabled.

2) I have a drawing area, in which I would like to plot a point (X-Y scatter plot). The plot should be generated dynamically using a C script. I am not sure how the integration between the two is possible for a drawing area.

In glade what properties of drawing area should I set? eg.expose event, realize etc. I was thinking of using cairo for generating the plot.

Programming :: Bash - Read Content Of File To Variable And Use This Variable In For Loop ?

Aug 21, 2009

I'm trying to read content of file to variable and use this variable in for loop. The problem is, when I have c++ comment style in file - /*. Spaces in line are also interpreted as separated lines.

For example:

Code:

Changing $files to "$files" eliminate these problems but causes that whole content of variable is treated as one string (one execution of loop).

i need to make a new variable with the string from the old variable btut without any plus sign. I have tried a lot of different ways with no success, each thing I tried either left the + or removed the entire string. I think this should work but doesn't

Programming :: SORT Command Versus Unix SORT

May 4, 2010

We switched from unix to linux and we have an old report that extracted data from a database, output to an ascii file and then sorted the results in the file based on different arguments. The report now blows up when it runs,and I can only guess it is because the options for sort on linux differ slightly from unix.For example, here is one of the commands issued from within the report app that ran on the old unix box:

if sort-sequence = "descending" then
'sort -t~" -f +3.0f -4.0 +5.0r -6.0 -f '
else
'sort -t~" +3.0f -4.0 +1.0f -2.0 -f'

I will eventually rewrite the report to store the data in a local table, but I can simply adjust the options to suit the requirments of linux. Basically, I need to know if this can be a quick fix for the short term.

Programming :: Extract Values From Array PHP

Jul 2, 2009

The idea is to make a website to check the availability of domains and it works but its not pretty yet. Below is what i have till so far:

## this is the API from my domain registrar.
<?php $client = new SoapClient('http://api.sync.com/?wsdl');
## I have a search box that sends the request to this page
$var = $_GET ["s"];

## remove the most common subdomains from the request.
$var=eregi_replace("www.", "", $var);
$var=eregi_replace("mail.", "", $var);
$var=eregi_replace("ftp.", "", $var);
$var=eregi_replace("pop.", "", $var);
$var=eregi_replace("smtp.", "", $var);

## remove any TLD extension from the request.
$split = explode(".", $var);
$main = $split[0];
$arraysize = sizeof($split);
for ($x=1; $x<$arraysize; $x++) {
$tld .= "." . $split[$x];
}
## login to the API
$paramLogin = array('handle' => 'randall', 'password' => 'password');

## match the domain with any possible TLD
$varcom = $paramAvailDomain = array('sld' => $main, 'tld' => 'com');
$varnet = $paramAvailDomain = array('sld' => $main, 'tld' => 'net');
$varorg = $paramAvailDomain = array('sld' => $main, 'tld' => 'org');
$varbiz = $paramAvailDomain = array('sld' => $main, 'tld' => 'biz');
$varinfo = $paramAvailDomain = array('sld' => $main, 'tld' => 'info');
$vareu = $paramAvailDomain = array('sld' => $main, 'tld' => 'eu');
$varnl = $paramAvailDomain = array('sld' => $main, 'tld' => 'nl');
$varbe = $paramAvailDomain = array('sld' => $main, 'tld' => 'be');
$varde = $paramAvailDomain = array('sld' => $main, 'tld' => 'de');
$varcouk = $paramAvailDomain = array('sld' => $main, 'tld' => 'co.uk');
$varorguk = $paramAvailDomain = array('sld' => $main, 'tld' => 'org.uk');
$varname = $paramAvailDomain = array('sld' => $main, 'tld' => 'name');
$varmobi = $paramAvailDomain = array('sld' => $main, 'tld' => 'mobi');
$varin = $paramAvailDomain = array('sld' => $main, 'tld' => 'in');
$vartv = $paramAvailDomain = array('sld' => $main, 'tld' => 'tv');
$varcn = $paramAvailDomain = array('sld' => $main, 'tld' => 'cn');
$varws = $paramAvailDomain = array('sld' => $main, 'tld' => 'ws');
$varnu = $paramAvailDomain = array('sld' => $main, 'tld' => 'nu');
$varbz = $paramAvailDomain = array('sld' => $main, 'tld' => 'bz');
$varcc = $paramAvailDomain = array('sld' => $main, 'tld' => 'cc');

## this requests the domain.COM and domain.NET
$varcom;
$varnet;
?>
<div id="content">

## below prints the result
<?php
print "<html><body><pre>";
$result1 = $client->__soapCall('Login', $paramLogin);
echo "<b>Result Login:</b>
" . print_r($result1, true);

$result15 = $client->__soapCall('AvailabilityDomain', $varcom);
$resvarcom = var_dump($result15, true);
$result15 = $client->__soapCall('AvailabilityDomain', $varnet);
$resvarnet = var_dump($result15, true);

print "</pre></html>";
?>
<?php

## the returned array looks like this

Result Login:
Array
(
[code] => 200
[message] => Login succesful
)
array(3) {
["code"]=>
string(3) "200"
["message"]=>
string(20) "Domain not available"
["result"]=>
object(stdClass)#236 (1) {
["status"]=>
string(5) "TAKEN"
}
}
bool(true)
array(3) {
["code"]=>
string(3) "200"
["message"]=>
string(16) "Domain available"
["result"]=>
object(stdClass)#232 (1) {
["status"]=>
string(4) "FREE"
}
}
bool(true)
?>
## till so far it works

What I need to do is to make this ugly looking reply in to something more readable, basically if TAKEN print occupied and if free print its yours to grab. I have been struggling with the in_array function but i'm not getting anywhere close in getting it to work.

Programming :: PHP Array - Possible To Get More Than Two Values Per Entry?

Jun 13, 2009

I created a class which has to return an array. My problem is I need to return 3 entries per record for example:

Code:
array(
"2009-06-13", "John", "Doe";
"2009-06-13", "Paul", "Simon";
"2009-06-12", "Frank", "Herbert";
);

Can this be done? What is the syntax? Where is the documentation? If this can't be done, How would you return this to a class without using a DB?

Debian Programming :: Returning Different Values For Same Code?

I am developing a script to automate some database setup, but I have an issue I cannot figure out. I prompt for some input with whiptail and select a default if nothing is entered. However, if you do not enter anything, it normally returns 0, but this time it is returning an empty value.

Code: Select all  # This one does work!

  # Set the source path
  TMPPATH=$(whiptail --backtitle "Linux Build Configuration"
    --title "Source-Code Path"
    --inputbox "Default: $SRCPATH" 0 60

Programming :: Parsing And Storing Multiple Values Using 'awk'?

Jan 24, 2011

I have a variable in which the data is stored as below:

variable_test=0m0.001s 0m0.001s 0m0.001s 0m0.001s 0m0.001s 0m0.001s .....an so on.

There are lots of values in format like "3m1.057s" are stored in variable_test separated with an space between two such values. For exapmple, value is "3m1.057s" I need to save different parts of a value in three separate array variables such as the

var_hour=3
var_min=1
var_sec= 057

tell if this can be done using "awk". A "WHILE" loop might be used to separate and store theses values I guess?
