PHP - How Do I Get Php To Invoke A Bash Command When Someone Browses The Page In A Web Browser?

hello everybody!

This is just basic script, where i try to modify for the needs. I try to play with it. i want to parse some data. The whole script has  three parts:

1. Fetching
2. parsing
3. storing

i want to put all into one script: Two are allready put together - there all seems to be clear...
So  this thread is one that asks for  the combining two parts of a script - how to invoke a variable between them


What has happened untill now:
1st i need to have a connection to database lets say MySQL. I will suggest to use mysqli instead of mysql.
Well - okay i safe this db.php




$host="localhost"; //database hostname
$username="******"; //database username
$password="******"; //database password
$database="******"; //database name
?>

Now i am going to take a new script and  save this config.php
<?php
require_once('db.php'); //call db.php
$connect=mysqli_connect($host,$username,$password); //connect to mysql through mysqli
if(!$connect){
die("Cannot connect to host, please try later."); //throw error if any problem
}
else
{
$select_db=mysqli_select_db($database); //select database
if(!$select_db){
die("Site Database is down at the moment, Please check later. We will be back shortly."); // error if cannot connect to database or db does not exist
}
}
?>


Now i have to take care for the script, that takes the files (note this is very basic - it is only a proof of concept.
In the real situation i will take cURL since cURL is much much nicer and more elegant and faster etc.


<?php
require_once('config.php'); // call config.php for db connection
$content = file_get_contents("<-here the path to the file goes in-> Position XY! an URL is here ");

var_dump($content);

$pattern = '/<td>(.*?)<\/td>/si';
preg_match_all($pattern,$content,$matches);

foreach ($matches[1] as $match) {
    $match = strip_tags($match);
    $match = trim($match);
    var_dump($match);
$sql = mysqli_query("insert into tablename(contents) values ('$match')");
}

?> 


Note: This is just basic script, where you can modify it for your taste and can play with it.

Question:  If i have stored the URLs that i want to parse in a local file - how do i "call" them in the script.
How do i do the call to file where the URLs (there are more than 2500 URLs that have to be parsed) at the
following position: $content = file_get_contents("<-here the path to the file goes in-> Position XY! an URL is here ");


The folder with the URLs is stored in the same folder as the scripts reside!

Many thanks for all hints and for a starting point!

if i have to write more - or if you need more infos - or if i have to be more concrete, just let me know!


i love to hear from you!

This is a simple permutation function that i was converting from php:

string_gen(){
    declare -a chars=('a' 'b')
    max=4
    let length=${#chars[@]}-1
    n=0
    combination=" "
    for i in `seq 0 $max`;
    do
        let n=($n*($length))+($length)
    done 
    remainder=0
    for i in `seq 0 $n`;
    do
        current=$i
        combination=" "
        while [[ $current > 0 ]]
        do
           remainder=($current%$length)
           echo remainder
           if [ $remainder -eq 0 ]; then
                combination="$combination"${chars[$length]}
            else
                combination="$combination"${chars[$remainder]}
                current = $current/$length
           fi
        done
    done 
    echo $combination
}

What is wrong with the syntax?   Link to PHP version: http://stackoverflow...o-certain-lengt

I would like PHP to kick off the following command:
Code: [Select]
arp -a|sed 's/ /,/g'>arp.csv
I also have an executable makeArpFile.sh:
Code: [Select]
#!/bin/bash
arp -a|sed 's/ /,/g'>arp.csv
And I have tried executing it in php with the following:
$arp = exec("bash makeArpFile.sh", $output, $exit_code);
echo("Last line: " . $arp . "\n");
echo("Output: " . $output . "\n");
echo("Exit Code: " . $exit_code . "\n");
/*returns:
Last line: 
Output: 
Exit Code: 127
*/

I also tried just plain old:
$arp = exec("makeArpFile.sh", $output, $exit_code);
echo("Last line: " . $arp . "\n");
echo("Output: " . $output . "\n");
echo("Exit Code: " . $exit_code . "\n");
/*returns:
Last line: 
Output: 
Exit Code: 127
*/


I can run plain old arp>arp.txt but I really need it formatted in BSD style (arp -a>arp.txt) in order to be able to parse it properly later.

Any thoughts?

EDIT:
for fun I made a useBash.sh script that executed "bash makeArpFile.sh" still no luck.

    

First off I want to thank everyone that is involved here in passing on the knowledge. After all that is what its all about. Okay so I want to do a campaign on password awareness and try to capitalize a little off of it. I came across the Breached_Compilation which is 1.4 billion email and plain text passwords. It has bash scripting in it to search and parse out the info from plain text documents which are in folders then prints the results in terminal. The other thing is that it posts the passwords in clear text. How would I obfuscate a portion of the clear text passwords? What would be the best way to integrate this to PHP? I am new to coding in PHP so any help is very much appreciated. Thanks an advance.

Here is the Bash script.

#!/bin/bash
dir=$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )

if [ "$1" != "" ]; then
	letter1=$(echo ${1,,}|cut -b1)
	if [[ $letter1 == [a-zA-Z0-9] ]]; then
		if [ -f "$dir/data/$letter1" ]; then
			grep -ai "^$1" "$dir/data/$letter1"
		else
			letter2=$(echo ${1,,}|cut -b2)
			if [[ $letter2 == [a-zA-Z0-9] ]]; then
				if [ -f "$dir/data/$letter1/$letter2" ]; then
					grep -ai "^$1" "$dir/data/$letter1/$letter2"
				else
					letter3=$(echo ${1,,}|cut -b3)
					if [[ $letter3 == [a-zA-Z0-9] ]]; then
						if [ -f "$dir/data/$letter1/$letter2/$letter3" ]; then
							grep -ai "^$1" "$dir/data/$letter1/$letter2/$letter3"
						fi
					else
						if [ -f "$dir/data/$letter1/$letter2/symbols" ]; then
							grep -ai "^$1" "$dir/data/$letter1/$letter2/symbols"
						fi
					fi
				fi
			else
				if [ -f "$dir/data/$letter1/symbols" ]; then
					grep -ai "^$1" "$dir/data/$letter1/symbols"
				fi
			fi
		fi
	else
		if [ -f "$dir/data/symbols" ]; then
			grep -ai "^$1" "$dir/data/symbols"
		fi
	fi
else
	echo "[*] Example: ./query name@domain.com"
fi

 

I'm trying to make colourized output of bash script in php. So far I have this:

<?php
$cmd = '/home/thebalk/FiveM/manage.sh restart';
while (@ ob_end_flush()); // end all output buffers if any

$proc = popen($cmd, 'r');
echo '<pre>';
while (!feof($proc))
{
    echo fread($proc, 4096);
    @ flush();
}
echo '</pre>';

//
// Converts Bashoutput to colored HTML
//
function convertBash($cmd) {
    $dictionary = array(
        '[1;30m' => '<span style="color:black">',
        '[1;31m' => '<span style="color:red">', 
        '[1;32m' => '<span style="color:green">',   
        '[1;33m' => '<span style="color:yellow">',
        '[1;34m' => '<span style="color:blue">',
        '[1;35m' => '<span style="color:purple">',
        '[1;36m' => '<span style="color:cyan">',
        '[1;37m' => '<span style="color:white">',
        '[m'   => '</span>'
    );
    $htmlString = str_replace(array_keys($dictionary), $dictionary, $cmd);
    return $htmlString;
}
?>

and my output looks like this:

[1;36m BOT:[0;39m THE [1;32m TheBalkanRP-SRV01-test SERVER [0;39m WAS RUNNING [1;36m BOT:[0;39m STOPPING THE [1;32m TheBalkanRP-SRV01-test SERVER [1;36m BOT:[0;39m GTA V SERVER HAS STOPPED [1;36m BOT:[0;39m REMOVING CACHE FOLDER [1;36m BOT:[1;31m CACHE FOLDER HAS BEEN REMOVED [0;39m [1;36m BOT:[0;39m STARTING THE [1;32m TheBalkanRP-SRV01-test [0;39m SERVER [1;36m BOT:[1;32m SERVER HAS STARTED [0;39m

I know my function is not connected with the code above but what is the right way to do it? Thank you!

For those not knowing about this, is a new security hole found in all linux/unix based operating systems that should be patched. http://arstechnica.c...with-nix-in-it/

Does anyone already fix the bug. I found something interesting in the error_log file this morning       x.x.x.x - - [25/Sep/2014:01:12:34 -0500]  "GET /cgi-bin/defaul_p.cgi HTTP/1.0" 404 312 "-" "() { :;}; /bin/ping -c 5 "209.126.230.74"        

Hey y'all.

Probably a dumb question here but I'm at a loss. I've got a PHP service script that has an include, written as so:

$config = new Config('config/config.json');

The config directory is next to the PHP script and does contain the config.json file, so when I run this from the CLI everything works great. However, I've got about 17 PHP services I need to start and really don't feel like typing them all out, so I've written a shell script that does this:

#!bin/bash


cd /path/to/my/script

/usr/local/bin/php ./my-script.php

This does start the service, but it bombs out because it can't find the config.json file.

If I change the PHP to 

$config = new Config('./config/config.json');

it works as expected from the shell script. Updating the files is technically possible, but fraught right now for reasons I can't really get into (sorry). Anybody know what the difference is, or have any ideas on how to get around this?

Hello!
I am executing an external command from a PHP script, using the exec function. Since this program can take more than 1-2 minutes to run, I thought I should use a "Loading page...please wait". What I need is to be able to get the process id from the external program that is being run and, when this finishes, I'll start outputting the results.

Is there a way to do this?

Hi, I'm new. I have been searching for this, but couldn't find my answer ...

I've got a form on page A, with its 'action' attribute set to page B.php.
Page B does nothing but process the form data & put it in a database.
At the bottom of B.php there's a header redirect to page C. 

My problem is that page B shows up briefly in the browser, looking all blank and weird. Is there a sensible way around this? I just want it to do its stuff in the background.

I realise I should be Ajaxing it all but, apart from the fact that I struggle with Ajax operations longer than a couple of lines, it's important that the site should work without javascript.

I HOPE this is a really easy one! Thanks

Hi, suppose the user requests a page www.foo2.php. Now if it is a link embedded in another page, say www.foo1.php, then Javascript can send the server browser info before furnishing the page. But is it possible to let the server know which browser is being used when the user requests the page by just typing the url http://www.foo2.php and hitting enter?

i am facing issue with DB connection with Oracle DB

i am getting err 500 when trying to open php page from front end. 

 

pls help...!!!! 

I have created a tar file with my site backup and I assume it is the full backup.  Not sure becasue I can't "un"-tar the file.

I have tried several ways to "unzip" or untar the file but can not come up with anything.


here is how I had created the tar file:
Code: [Select]
$date = date("m-d-Y");

// repeat this command for multiple backups, changing the path - e.g. you can have a backup for email, another for files, etc.
shell_exec("tar cvfz file_backup_$date.tar.gz mydir/ ");

now how do extract it?

I have a shoutbox my friend made, and I'm just adding onto it.

I have command that are like @prune, @prunelogs, @logout, etc.. I am tying to make it so you can type @ban username, @unban username, etc..

Here is my command that my friend came up with.
if($_POST['text'] == '@ban'.$username.'') {
$unn=$idk['username'];
mysql_query("UPDATE users SET banned = '1' WHERE usernane='$unn'") or die(mysql_error());
mysql_query("INSERT INTO chat (`log`, `date` ,`username` ,`text`) VALUES (1, NOW( ) , '".stripslashes($_SESSION['user'])."', 'has banned '$unn'.');") or die(mysql_error());
