-------------------------------------------------------------------------------- /Autonomous/Sem7/Web Lab/README.md: -------------------------------------------------------------------------------- 1 | ## Running Perl programs 2 | 3 | ### On Ubuntu Linux (with Apache installed) 4 | 5 | Place all the perl script files in the folder meant for CGI scripts as mentioned in the configuration file in `/etc/apache2/sites-available/default`. Mostly this will be /usr/lib/cgi-bin by default. Follow this [link](http://prometheansacrifice.wordpress.com/2013/12/07/running-perl-cgi-scripts/) for more details. 6 | 7 | Access them on the browser using `http://localhost/cgi-bin/filename.pl` 8 | 9 | Make sure to give `x` access to the `.pl` files 10 | 11 | sudo chomd a+x filename.pl 12 | 13 | Its convenient to login as root to execute these programs. In such cases, `sudo` i unnecessary. 14 | 15 | ### On Fedora Linux as prescribed by the VTU 16 | 17 | Place the perl files in /var/www/cgi-bin. Access them on the browser using `http://localhost/cgi-bin/filename.pl` 18 | 19 | 20 | ## Running HTML and PHP 21 | 22 | ### On Ubuntu 23 | 24 | HTML and PHP files can be placed in `/var/www` itself and can be accessed from the browser as `http://localhost/filename.php` or `http://localhost/filename.html` 25 | 26 | ### On Fedora 27 | 28 | HTML and PHP files are placed in `/var/www/html`. Access them on the browser like Ubuntu. -------------------------------------------------------------------------------- /Autonomous/Sem7/Web Lab/pg1/mystyles.css: -------------------------------------------------------------------------------- 1 | p,table,li 2 | { 3 | font-family: "lucida calligraphy", "comic sans", "sans serif"; 4 | margin-left: 5pt; 5 | } 6 | p { word-spacing: 5px;} 7 | body { background-color:rgb(200,255,205);} 8 | 9 | p, li, td { font-size: 75%;} 10 | td { padding: 0.5cm ;} 11 | th 12 | { 13 | text-align: center; 14 | font-size: 85%; 15 | } 16 | 17 | h1,h2,h3,hr 18 | { 19 | text-align: center; 20 | color: #483d8b; 21 | } 22 | 23 | table 24 | { 25 | border-style: outset; 26 | background: rgb(100,255,255); 27 | } 28 | 29 | li { list-style-type: lower-roman;} 30 | 31 | span 32 | { 33 | text-align: center; 34 | color: white; 35 | background-color: blue; 36 | font-size:29pt; 37 | font-style: italic; 38 | font-weight: bold; 39 | } -------------------------------------------------------------------------------- /Autonomous/Sem7/Web Lab/pg1/p1.html: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | LAB PROGRAM! 5 | 6 | 7 |

 1 | ### Aim:
 2 | C program that creates a child process to read commands from the standard input and execute them (a minimal implementation of a shell-like program). You can assume that no arguments will be passed to the commands to be executed.
 3 | 
 4 | #### Description:
 5 |  
fork():it is a system call which forks a new child of a processs
 6 | 
system ():it is a system call which takes a command as an argument and invokes the operating system to execute it.

The parent process waits for its child to finish (by executing the wait( )) and prints its own process-id and the id of its child process and then exits.
 3 | 
 4 | ### Description:
 5 | 
pid_t:parent id of the process.
 6 | 
fork():it is a system call which forks a new child of a processs

--------------------------------------------------------------------------------
/VTU/Sem6/USP_CD_Lab/05aEnvironList/5a_environlist.md:
--------------------------------------------------------------------------------
 1 | ## Aim :
 2 | 
 3 | ### Write a C/C++ program thgat output the contents of its Environment list.
 4 | 
 5 | 
 6 | ## Theory :
 7 | 
 8 | >Environment variables are a set of dynamic named values that can affect the way running processes will behave on a computer.
 9 | 
10 | >They are part of the operating environment in which a process runs. For example, a running process can query the value of the TEMP environment variable to discover a suitable location to store temporary files, or the HOME or USERPROFILE variable to find the directory structure owned by the user running the process.
11 | 
12 | 
13 | ## Code :
14 | 
15 | 

16 |  #include<stdio.h>
17 |  #include<unistd.h>
18 |  int main(int argc,char *argv[])
19 |  {
20 |   char **ptr;
21 |   extern char **environ;
22 |   for(ptr=environ; *ptr; ptr++)
23 |    printf("%s\n",*ptr);
24 |   return 0;
25 |  }
26 | 

27 | 
28 | 
29 | 
30 | ## Output:
31 | 
    
32 | 
  • Open a terminal.
    • 
33 | 
  • Change directory to the file location in both the terminals.
    • 
34 |  
  • Open a file using command followed by program_name 
    vi 5a_environlist.c 
     and then enter the source code and save it.
    • 
35 |  
  • Then compile the program using 
    gcc 5a_environlist.c
    • 
36 |  
  • If there are no errors after compilation execute the program using 
    ./a.out 
    •

 2 | ***
 3 | 
 4 | ### Tags used:
 5 |      'Refresh:1' - used to dislay the refreshed time every second
 6 |      localtime() - uses the current time.

30 | ### Output:
31 | *Steps for checking output-*
32 | 
33 | * Save the .html file in the folder `/var/www/html`
34 | * Save the .pl files in the folder `/var/www/cgi-bin`
35 | * Change the file permission of the perl file by running the command `sudo chmod 777 7.pl`
36 | * Open a browser and in the address bar type `localhost/html/7.html`
37 | * Click the button `Click_to_display_time` to view the current time of the server.
