Programming :: Use Awk And Sed To Extract Height And Width Of File

Aug 3, 2010

I am trying to write commands that extracts the height and width of a video file via ffmpeg. I have the following working so far:

This gives the following answer in widthxheight format with an extra , 720x480,

How can I instead run 2 separate commands that give me height and width separately? I want some command to give me 720 and another command to give me 480 and I dont need the x or the ,

If you need to know this is what ffmpeg -i videofile.mov 2>&1 gives as output

Seems stream 0 codec frame rate differs from container frame rate:

At least one output file must be specified

Software :: Imagemagick - Height-and-width Not Deterministic When Crop An Png File

Sep 8, 2009

After spending a few hours and having some little sleep, I am very puzzled and disturbed by the fact that new-new-02-5-1.png does not have the intended 818x788. It must have to do with cropping with nonzero offsets.

Programming :: Adjust Table Width So That It Fits To Page Width

Mar 22, 2010

A couple of days I started using latex and have still one question about the table width. My table is too wide for a page. How can I adjust it so that it fits on the full width of a page? Can I use a command or do I have to specify each column widths by hand?

My table looks like this;

I did try several commands likeextwidth, esizebox, setlength but didn't found the solution yet.

Programming :: Get Console Window Width - Why Ioctl Always Return 0 Width

Jul 1, 2010

I use ioctl to get the cosole window size (the SSH window).

I use the following code:

When I debug on linux pc, it gives me the correct window width. But after I try it on router (this is my enventual place where my code shall run), ioctl always give me 0 width, that is, numberOfColumnsOfTerminalWindow == 0. but the returnValue is 0 which means that the function call succeeds.

Programming :: Extract 2 Numbers From A Same File?

Dec 22, 2010

I am trying to extract 2 numbers from a same file and my goal is to print them both in another file, on the same line, separated with a space. I have to do that for 20 files and I would like to have therefore 20 lines like this in the output file. It would look like this :

Quote:

number1_file1 number2_file1
number1_file2 number2_file2
...
...
number_1_file20 number2_file20

So far, I did only extract one number and got an output file like this :

Quote:

number1_file1
number1_file2
...
...
number1_file20

And I did this by running a bash script with the following content :

Code:

#!/bin/bash
ls execution$1$2*.* | while read filename
do
cat $filename | grep -e "Total aborts:" | cut -d " " -f3 >> abort$1$2.dat
done

$1 and $2 are just strings to identify the different files I want to consider in this loop. This script works well to extract a number which is the 3rd field of a line starting with "Total aborts:".Now, how could I change this script to do what I mentioned above (i.e. extracting two numbers from two different lines) ? The second number is the 3rd field of a line starting with "Total throughput:"

Programming :: Extract Extra Packages In A Separate File?

Mar 6, 2009

I have two files containing list of packages using

Code:

dpkg --get-selections > file-name
command.
package-a.txt

[code]......

Now I would like to create a third file which contains only those packages which are present in package-a.txt but NOT in package-b.txt. The file should look like this:

Code:

package2
package4

Note: The world "install" is also to be removed for all packages. Using diff command I could get something like this:

Code:

temp# diff -yb package-a.txt package-b.txt | grep "<"
package2 install <
package4 install <
<
temp#

But not sure how to remove instances of "install" and "<".

Programming :: How To Find Out Width Of Terminal

Ubuntu :: File System - Whenever Extract A File From A .tar Or Whatever - It Isn't Detected

Sep 1, 2011

When ever I extract a file from a .tar or whatever, it isn't detected. I notice this mainly when i'm using xampp. I copy zip up all my files on one computer, load ubuntu on another, extract the files to the web folder (htdocs) and then I get nothing. However, when I manually create the files directly on my computer as opposed to extracting them, they appear.

Is there something I need to do in order to have these files appear? Is there some sort of file system refresh? Or am I being a complete idiot?

Programming :: Extract The Text From Files?

Aug 28, 2010

I have many files in a folder from which I need to extract some contents, these are basically text files wich have individual lines with (i.e)

name: john
address: whatever
phone: 123456

Some caveats

1. Sometimes a line might be missing.

name: johnn
phone: 123456

2. Lines are not in the same line-numbers across the files I did try some things with awk based on google searches but I couldn't extract the data of each file into a single line (this is the ultimate goal):

john,whatever,123456

I don't have knowledge other than having put some bash scripts together for backup jobs, so I am open to install anything that could to pull this off.

Programming :: Extract URL From Firefox Address Bar ?

Nov 27, 2010

I'm trying to create an application that monitors, among other things, what site the user is currently viewing. I would like to know if there is any way to get the current URL from the Firefox's address bar on a Linux machine. I know that under Windows I can use the DDE server approach, but under Linux this task is proving very tricky. I've considered an approach involving an extension to Firefox, but this would require the user to install the said extension himself. Which is not something I want. If an extension can be installed by a different program's installer than that could work, but I don't know if that's possible or not.

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 :: Extract Metadata From Image

Mar 13, 2009

I am trying to get the metadata out from an image file in python. I have tried using PIL but it does not give me the data I am looking for (mostly just got a bunch of hex code) and I have no idea how to use ImageMagick, the python module is poorly documented and I can't find any examples on the net.The info I need is stuff like camera model, if flash was used, focal length, exposure time, date, etc.. pretty much the same info I get when I look at the "Image" tab on properties in Nautilus on Ubuntu.

What I am doing is writing a script that will iterate through a lot of pictures and put all this metadata into MySQL. I chose python since it is simple and I am familiar with it. But I can't find a good way to get that metadata from within python.

Programming :: Extract A Substring Using Regular Expression With SED

May 7, 2011

I've spent most of the evening browsing the web, trying many things I've found on various forums, but nothing seems to work.

I have a test.txt file containing many lines like the following ones :

...
<insert_random_text>228.00 €<insert_more_random_text>
<insert_random_text>17.50 €<insert_more_random_text>
<insert_random_text>1238.13 €<insert_more_random_text>
...

And I want to extract :

...
228.00
17.50
1238.13
...

There is always one occurrence of € in each line. I want the numeric value that precedes this € occurrence. The random text (before and after) may contain numbers too, so the € may be important to parse, in order to correctly identify the number to return. The last character that precedes the number to extract is always a ">" (coming from an HTML tag).

Now, I want to extract a subset from this file. In this subset, column 1 is x10, column 2 is from 600000 to 30000000. I wrote the following perl script but it doesn't work:

#!/usr/bin/perl
$file1 = $ARGV[0]; # Input file
$file2 = $ARGV[1]; # Output file

I guess the input file and output file are both too big that my script can't handle it.
