I'm trying to execute the following command from PHP, the problem is that I tried "PING", "netstat -a" and "ls", all of them worked fine and I got the output.
Wpscan is a Wordpress bug scanner, it's written in ruby, I installed it in the server and used this command to make it executable from anywhere
sudo ln -s /home/ubuntu/wpscan/wpscan.rb /usr/local/bin/wpscan
As you can see I tried the same command on the shell and it is working fine. I don't know what's the problem with the PHP code.
wpscan command
$cmd = 'wpscan -u www.google.com';
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>';
?>
Update:
I just put the following "2>&1" at the end of the command and I got the following error:
/home/ubuntu/wpscan/lib/common/common_helper.rb:6:in home': couldn't find HOME environment -- expanding~' (ArgumentError)
from /home/ubuntu/wpscan/lib/common/common_helper.rb:6:in '

from /usr/local/bin/wpscan:8:in `
Update2:
I just checked the users of PHP script and shell.
PHP: www-data
Shell: ubuntu

I have a python script that i want to run from index.php and they both are in the same directory.
The problem is that there's no output shown on the page(index.php).
I am running the page on a CPanel shared hosting from GoDaddy.
I have the permissions -rwx for both the files.
There's no error in running the python3 script file from the terminal.
The same files run smoothly on my computer's localhost but not on the CPanel.
Am able to run bash files using the same php code.
I have tried using system() in php to call the python3 script file but this doesn't seems to work.
index.php:
<?php
$comm = "python3 test.py";
echo $comm;
$output = system($comm);
echo "\n";
print($output);
?>
test.py:
print ("Hello")
Current Output:
python3 test.py
I expect the output to be:
python3 test.py Hello
I think you will need to use shell_exec to run your python code like that
<?php
$command = escapeshellcmd('/usr/custom/test.py');
$output = shell_exec($command);
echo $output;
?>
and the first line in the python file should be
#!/usr/bin/env python
Don't forget to give your python file the privileges
chmod +x test.py
I have a php web application and on one of the route I try to execute node script.
Node script location: C:\Users\meusr\Workspace\www\myproject\directImport.js
I have configured my package.json, such that npm start executes above script.
php (laravel) application's executable index.php located at: C:\Users\meusr\Workspace\www\myPHPproject\public\
And on one of my route: importer/run
I have:
$commandToRun = "npm start --prefix ". env('IMPORTER_PATH'). " /dev/null 2>&1";
Where IMPORTER_PATH is configured in my env, as: IMPORTER_PATH = C:\Users\meusr\Workspace\www\myproject\
when I try to execute the command with exec
exec($commandToRun, $output);
Page keeps on loading no output, no error and no end.
The script has no issue and running the same command on command line on windows system works:
npm start --prefix C:\Users\meusr\Workspace\www\myproject\
outputs as expected.
I thought it was issue with permission first (which should have thrown error, but I still tried and ran another command)
exec('npm -v', $output);
which outputs my npm version.
Similarly I tried to use simply node directImport.js which didn't work either.
Then tried to change directory to the location where node file is located and ran the command again.
exec(cd C:\Users\meusr\Workspace\www\myproject\ && dir /dev/null 2>&1) // this works, but:
exec(cd C:\Users\meusr\Workspace\www\myproject\ && node directImport.js /dev/null 2>&1) // this didn't work
Thanks to miken32, what worked for me was:
<?php
$commandString = 'start /b c:\\programToRun.exe -attachment "c:\\temp\file1.txt"';
pclose(popen($commandString, 'r'));
?>

I tried many solutions but nothing it works :
echo '<pre>';
shell_exec("python /home/folder/python/mapfile_compress.py");
shell_exec("sudo -u wwwexec python escapeshellcommand(/home/folder/python/mapfile_compress.py) $uid");
shell_exec("sudo chmod +x /home/folder/python/mapfile_compress.py");
system("bash /home/folder/python/mapfile_compress.py");
passthru("bash /home/folder/python/mapfile_compress.py");
passthru("/home/folder/python/mapfile_compress.py");
exec("bash /home/folder/python/mapfile_compress.py");
echo '</pre>';
I launched indivdually them but in all cases, Firebug returned : '<pre>'
So I tried this code founded on Stack Overflow :
$command = escapeshellcmd('chmod +x /home/folder/python/mapfile_compress_test.py');
echo $command;
$output = shell_exec($command);
echo $output;
But firebug returned nothing.
My python file begin with #!/usr/bin/env python and if I launch it on server that works !
Do you knwo how can I launch my python file from PHP file ?
chmod will return 0 on success and > 0 on error.
Make sure that the file is able to run by just executing it as the web user. When +x is properly set, you can execute it by just calling $ /path/to/your/file.py, the shebang in the first line in your script #!/usr/bin/env python should define the correct python based on your env.
You can test this by running:
$ /usr/bin/env python /path/to/your/file.py
So check your file permissions to check if the file is executable by the user that runs the php script.
Just to test, you can just print a few lines in your python file
#!/usr/bin/env python
print "test line 1"
print "test line 2"
Then if you have verified permissions and the correct use of python, you can do this in your php.
$command = escapeshellcmd('/path/to/your/file.py');
$output = shell_exec($command); // get all output or use passthrough, exec will only return the last line.
echo "<pre>{$output}</pre>;
At first, Do you have enabled shell_exec/system/passthru commands in php.ini?
shell_exec("python /home/folder/python/mapfile_compress.py");
I think, it could be problem with your $PATH. Try something like: (use full path to python)
shell_exec("/usr/bin/python /home/folder/python/mapfile_compress.py");
shell_exec("/usr/local/bin/python /home/folder/python/mapfile_compress.py");
In my case that's work if I write this code :
$command = escapeshellcmd('python /path/to/your/file.py');
exec($command);
I have a shell script in Linux that performs SFTP to get some files. It works fine when I execute it from a terminal.
I am trying to call the script from PHP. It seems to work until the echo, and then it doesn't do anything.
The script and the PHP file are in the same folder.
This is the PHP code:
<?php
$comando = "sh ftpgesdoc.sh";
$result=exec($comando);
echo $result;
?>
And this is shell script. When I execute from the web, I can see the echo "ejecutando sftp", but nothing happens after this point.
#!/bin/sh
echo "ejecutando sftp"
folder="/aaa/bbb"
file="xxx.PDF"
sftp UserXX#nnn.nn.n.nn << EOF
cd $folder
get $file test.pdf
EOF
exec returns only the last line from the command output. If you want to capture entire output, use proc_open. See this answer, for instance.
you have to give the full path to file
and use this 2>&1 and know the error
try something like this
$comando = "sh pathTofile/location/ftpgesdoc.sh";
if(exec("$comando 2>&1", $output, $return_var))
{
print_r($output);
echo "<br>";
print_r($return_var);
}
I am trying to run a bash script from the web using php exec() method. The same bash script when ran from the terminal ./test.sh works fine executes all the command without any error. But when i try to run it from the command line it would absolutely not work. They both are in the same location. I have even give chmod 777 permission to that file.
Commnads like ls , pwd etc work but cf isn't working ?
test.sh
/usr/bin/cf login -a https://api.stage1.ng.bluemix.net -o jetmak#ca.blue.com -s dev -u jenk#ca.blue.com -p pass22
/usr/bin/cf api
/usr/bin/cf
executeshellfromphp.php
header('Content-Type: application/json');
$bluemixid = $_POST['bluemixid'];
$bluemixpwd = $_POST['bluemixpswd'];
$env = $_POST['env'];
$restart = $_POST['action'];
$result =shell_exec('sh /var/www/shellscriptphp/test.sh '.$env.' '.$restart.' '.$bluemixid.' '.$bluemixpwd.' ');
echo json_encode(array("result"=>$result));
exit();
