Just issue the following in the folder of the source codes and replace ‘FIND ME’ with the string you want to query:
find -O3 . -regex '.*\.\(c\|cpp\|h\)
You can change the contents of the regular expression to search in different file extensions (file types).
-exec grep 'FIND ME!' -sl '{}' \;
You can change the contents of the regular expression to search in different file extensions (file types).
g++ -O3 -Wall skala.cpp; time ./a.out; i=$(($i+1)); cp cy2012b1.in cy2012b1.in.$i; cp cy2012b1.out cy2012b1.out.$i
a.out reads from the input file and produces the expected result in the output file.
First of all you will need a page the will keep record of the registrations.
To do the paste the following code in a *.php file on a php-enabled webserver:
<html>
<body>
<?php
if (isset($_GET["ip"]) && isset($_GET["name"]))
{
echo "Current Time " . gmdate("d/m/Y H:i:s e", $_SERVER['REQUEST_TIME']) . " IP " . $_GET["ip"] . " Hostname " . $_GET["name"] . "!<br/>";
$file=fopen("cookies.txt","a") or $file=fopen("log.txt","x");
fwrite($file,"Time " . gmdate("d/m/Y H:i:s e", $_SERVER['REQUEST_TIME']) . " IP " . $_GET["ip"] . " Hostname " . $_GET["name"] . "\n" );
fclose($file);
}
else
{
echo "Welcome Murloc!<br />";
echo "Following the SSH Login Log File:<br /><br />";
$file=fopen("log.txt","r") or $file=fopen("cookies.txt","x");
while(!feof($file))
{
echo fgets($file). "<br />";
}
fclose($file);
echo "Your IP is ".$_SERVER['REMOTE_ADDR']. "<br />Current Time " . gmdate("d/m/Y H:i:s e", $_SERVER['REQUEST_TIME']) . "<br /><br />";
echo "Bye Bye Bob<br />";
}
?>
</body>
</html>
The above php script will store your IP and Hostname if you provide them on the URL along with the time that the event happened and if you do not then it will list the registered IPs.
NOTE:Not sure how safe this code is
In order to invoke it / send you IP and hostname, issue form bash the following:
IPs=`ifconfig | grep 'inet addr:'| grep -v '127.0.0.1' | cut -d: -f2 | awk '{ print $1}'`
wget "http://www.example.com/ip.php?ip=$IPs&name=$HOSTNAME" -o /dev/null
Just add the command(s) you want in the file
/etc/init.d/rc.local
Make sure that they do not block or cause errors 🙂
