I want to run a shell file from php using this command:
system('./12.sh');
And the content of that shell file is as follows:
#!/bin/bash
source ~/.virtualenvs/cv/bin/activate
python /home/raul-pc/Documentos/codigo/rec_face.py
When I run the php program from the Terminal everything works fine using this command:
cam programa.php
But what I want is to be able to run it from the server. How can I achieve this?
PHP has a method to execute shell commands. It's called shell_exec :
Execute a command using the command interpreter and return the full output as a string.
Syntax
string shell_exec ( string $cmd )
Parameters
cmd
The command that will be executed.
Return values
The output of the executed command or NULL if an error occurs or the command produces no output.
Note: This function can return NULL when an error occurs or when the program does not produce any output. It is not possible to detect the execution failures using this function. exec () should be used when necessary to access the exit code of the program.
Ejemplo #1 Un ejemplo de shell_exec()
<?php
$salida = shell_exec('ls -lart');
echo "<pre>$salida</pre>";
?>
Note: This function is disabled when PHP is running in mode sure.
<?php
$salida = shell_exec('uname -a');
echo $salida;
?>
