I have a bash script as below :
#!/bin/bash
for i in `cat domains` ; do
tag=$(echo -n $i" - "; whois $i | grep -o "Expir.*")
reg=$(echo -n -" "; whois $i | grep "Registrar:")
echo $tag $reg
sleep .5s
done;
I wish to have a php page where a user can paste in a list of domains and when they hit send it calls the bash script processes the domains and returns the output. Is this possible?
It is possible, but you will need to take care when executing a command with user input. You can use exec() or backticks to execute a command on the server from PHP.
Just take care to make sure that what the user entered is actually a URL and not something meant to execute a malicious command on your server.
Your code might look something like this:
$output = array();
$urls = $_POST["urls"];
// perform necessary sanitation checks if needed
exec('/path/to/your/script '. implode(' ', $urls), $output);
echo $output;
"$i" to prevent wildcards from being expanded.
addslashes in my PHP version of his script.yep you can use exec() or shell_exec() command
proc_open, it allows you to provide pipes for input and output of the process.Do you really need to run the bash script? Here's the equivalent PHP code:
foreach ($domains as $domain) {
$domain = addslashes($domain);
exec("whois '$domain'", $results);
foreach ($results as $line) {
if (preg_match('/Expir.*/', $line, $matches)) $tag = $matches[0];
if (preg_match('/Registrar:/', $line)) $reg = $line;
}
echo $domain.' - '.$tag.' - '$reg."\n";
usleep(500000);
}
while read -r i; do ...; done < domains. See Bash FAQ 001.
