Hi all ! Can someone please explain what the following command does:- sudo sed -i s,scotchbox.local,$DOMAIN,g /etc/apache2/sites-available/$DOMAIN.conf sudo sed -i s,/var/www/public,/var/www/$DOMAIN/public,g /etc/apache2/sites-available/$DOMAIN.conf I can across these commands in here. I have tried them out in the terminal as a modified example :- sudo sed -i, s,www,the,g test.txt. where test.txt has 2 lines of some text containing the word 'the' a couple of times. The command seems to do nothing. There is no change in test.txt. I cannot get any example of sed -i, s on google. In fact i cannot get a similar example of sed anywhere on google. But then i believe sed is extremely versatile and has tons of usages. Grateful for any help. Thanks all.

hello dear community I’m trying to capture the output of the top command into a file. When I execute top > output.txt, the output.txt file contains lot of junk characters. What is the best method to capture the output of the top command into a readable text file? i tried to use the top command batch mode operation option ( -b ) to capture the top command output into a file. top -n 1 -b > top-output.txt or this one less top-output.txt but - unfotunatly they do not work for me... : linux-a9sq:/home/martin # -n 1 > top-output.txt -n: command not found linux-a9sq:/home/martin # top-output.txt If 'top-output.txt' is not a typo you can use command-not-found to lookup the package that contains it, like this: cnf top-output.txt linux-a9sq:/home/martin # top -n 1 -b > top-output.txt linux-a9sq:/home/martin # top -n1 -b | head5 If 'head5' is not a typo you can use command-not-found to lookup the package that contains it, like this: cnf head5 linux-a9sq:/home/martin # what can i do!? love to hear from you greetings

In the following pages I'm trying to validate if a user is signed in or not. If the user is signed in I would like to see 'Log Out' printed to the screen(I'll do more with that later). If the user is not signed in I would like to see a login form at the top right of the screen. As it stands I'm only seeing 'Log Out' on the screen, I can't get the form to show up anymore. I thought it might be because the session variable was still hanging around but I restarted my computer to make absolutely sure but I'm still just getting 'Log Out'. At the moment I need this program to work as is as much as possible. If you see an entirely different approach that you would use that's fine but I don't currently have the time to go changing a lot, I need to get this going kinda quick. Thanks. records-board.php <?php require_once('includes/init.php'); if(!isset($_SESSION)) { init_session(); } ?> <html> <head> <Title>Pop Report</title> <link rel="stylesheet" type="text/css" href="styles/popreport2.css"> <h1>Pop Report</h1> </head> <body> <?php if(isset($_POST['nameinput']) && isset($_POST['passinput'])) { $nameinput = $_POST['nameinput']; $passinput = $_POST['passinput']; User::sign_in($nameinput, $passinput); } if(!isset($_SESSION['user'])) { print_form(); } else { echo "Log Out "; echo $_SESSION['user']->name; // this line was just trouble shooting, it told me nothing! } ?> user.php <?php if(!isset($_SESSION)) { init_session(); } class User { public $name; public function __construct($username, $password) { $connection = get_db_connection(); $query = $connection->query("SELECT * FROM users WHERE username='$username' AND password='$password'"); if(!$query) { echo "Invalid username or password"; } else { $result = $query->fetch(PDO::FETCH_ASSOC); if(!$result['username'] == $username || !$result['password'] == $password) { echo "Invalid username or password"; } else { $this->name = $result['username']; } } } public static function sign_in($username, $password) { $_SESSION['user'] = new User($username, $password); } } ?> <?php function print_form() { echo "<form id='loginform' name='loginform' action='records-board.php' method='post'>"; echo "Username: <input type='text' name='nameinput'>"; echo "Password: <input type='text' name='passinput'><br />"; echo "<input type='submit' value='Sign In'>"; echo "</form>"; } ?>

I'm getting the following errors when I run `cat /var/log/apache/error.log` -> PHP Notice: Undefined variable: db_connection in /var/www/html/popreport/includes/inmate.php on line 18 -> PHP Fatal error: Call to a member function query() on a non-object in /var/www/html/popreport/includes/inmate.php on line 18 When I try this in my browser I start with test.php test.php <?php require_once("./database.php"); require_once("./inmate.php"); // foreach($query as $row) // { // print_r($row) .

Any ideas?

[Linux] PHP Notice: Undefined variable: connection in /var/www/html/popreport/functions.php on line 23 PHP Fatal error: Call to a member function query() on a non-object in /var/www/html/popreport/functions.php on line 23 The fuction output in the following program is called from another file called records records-board.php If you look at the program below you'll see that I did define $connection above line 23 in the file functions.php And for the second error I'm really not getting it because that same foreach loop was working fine with the exact same argument list when it was in the file records-board.php, but now that I've copied most of the code from records-board.php and placed it in functions.php all the sudden my program can't see the variable $connection and has a problem with my foreach loop on line 23. Again, both of those lines worked fine when they were in another file. functions.php <?php //session_start(); // open a DB connectiong $dbn = 'mysql:dbname=popcount;host=127.0.0.1'; $user = 'user'; $password = 'password'; try { $connection = new PDO($dbn, $user, $password); } catch (PDOException $e) { echo "Connection failed: " . $e->getMessage(); } $sql = "SELECT full_name, tdoc_number, race, facility FROM inmate_board WHERE type = 'COURT'"; function output() { foreach($connection->query($sql) as $row) { echo "<tr><td>$row[full_name]</td></tr>"; } } ?> records-board.php <? include 'functions.php'; php output(); ?> Any ideas?

Hello All, Have a GoDaddy MySQL PHP:PDO hosting questions. Using a database class to make script queries. Unfortunately, I'm required to use GoDaddy Windows hosting. However, I'm a Linux kind of guy. Here's the issue. The viewer script includes database credentials defined as constants, in a file outside the root directory. Typically, these constants are available to all sub processes including class objects. Everything works as expected on development server. The error message I get with version using constants: L226: projectGallery_class datapull Caught Exception --- invalid data source name with host string userDBName.db.6482519.hostedresource.com;dbname=userDBName However when I deploy to GoDaddy's production server, the constants are defined - but empty. Here is the example code. /* works on Linux */ class datapull { var $host; // not assigned here var $userName; // not assigned here var $userPass; // not assigned here protected function conn() { try { $DB = new PDO(DB_HOST,DB_UNAME,DB_PASS); $DB->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); return $DB; } catch( Exception $e ) { $mes = "L226: datapull::conn() Caught Exception --- "; $mes .= $e->getMessage(); error_log($mes); } } public function dbquery($qqueue) { $DB = (!isset($DB)) ? $this->conn() : $DB; /* some query stuff here */ return $result } The modified class for GoDaddy Windows class datapull { var $host = “mysql:host=userDBName.db.1234567.hostedresource.com;dbname=userDBName”; var $userName = “userDBName”; //godaddy user and database naming convention var $userPass = “userPWDString”; //user password protected function conn() { try { $DB = new PDO($this->host,$this->userName,$this->userPass); $DB->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); return $DB; } catch( Exception $e ) { $mes = "L226: datapull::conn() Caught Exception --- "; $mes .= $e->getMessage(); error_log($mes); } } public function dbquery($qqueue) { $DB = (!isset($DB)) ? $this->conn() : $DB; /* some query stuff here */ return $result }

I've spent the last year building a web application on my local machines using the typical LAMP stack. I've been a developer for 10+ years and am fairly good when it comes to scripting but the server/hosting/system admin thing scares me. I've taken tons of sites live but they always exist on shared hosting and require minimal maintenence...simply ftp changes...no big deal. With my latest personal projects I've used revision control (git or mercurial) simply as a way to let me work from different machines. It's awesome. I push code from home, work, and my laptop and everything is in sync with one another. It really has changed the game for me. ( I use bitbucket) My latest project will involve paying customers and has a huge code base. FTPing files is not going to cut it. I've heard of having a "staging" environment so that you can push code to the staging environment, test it, and then push to production. That sound perfect! Every time I google git/staging I get pages and pages of command line stuff. I'm used to using version control GUI's like tower and sourcetree. Are there server environments that would allow me to use a GUI to manage version control? Or are linux server environments command line only? Are there any hosting companies you know of that would be a good fit for these needs? I'm looking to keep the hosting <= $20/month Thanks

hello - dear phpfreaks, i portet over a wordpress site to localhost. (an opensuse linux-box) all went nice and was very smooth to do so. after porting over the files and the db; i added the db-name and user-name etc. but nothing more. then i looked at the site http://localhost/mysite i saw the site - but only once - that is very very interesting. i read that i have to do more. Probably these changes - mentioned below are mandantory in order to avoid a blank page cf: https://managewp.com/how-to-create-a-local-copy-of-a-live-wordpress-site#comment-148613 question: is this true? Do i need to make these changes to avoid a blank page!?

I am using apache web server on linux. I am using php for coding. My php code is not able to read the files from /var/tmp folder. If apache itself creates some files in /var/tmp folder then php code is able to read it. Why this permission denied issues are there though full access permissions are given to each file? -
I am using apache web server on linux. I am using PHP for web designing. On web server, i want to show the configuration data by reading the ini file. I am creating this ini file from one php code itself. If this php code i run through linux terminal, the file is created with file and group owner as root.(i am having sudo rights on machine) Then if i try to read the ini file from my apache web server, it gives warning as failed to open stream: permission denied. I have tried changing the owner, and permissions to 777 of the file. Still it is not readable. On the other hand, if i run the php code of ini file creation through web server, ini file is created with file and group owner as apche. and web server is able to read/ write the file. But i want to create that file from root or some other user and later read/written by apache. How to give this access permission?
