Run Bash Command from PHP
PhpBashExecPhp Problem Overview
I have a bash script, that I run like this via the command line:
./script.sh var1 var2
I am trying to execute the above command, after I call a certain php file.
What I have right now is:
$output = shell_exec("./script.sh var1 var2");
echo "<pre>$output</pre>";
But it doesn´t work. I tried it using exec and system too, but the script never got executed.
However when I try to run shell_exec("ls"); it does work and $output is a list of all files.
I am not sure whether this is because of a limitation of the VPS I am using or if the problem is somewhere else?
Php Solutions
Solution 1 - Php
You probably need to chdir to the correct directory before calling the script. This way you can ensure what directory your script is "in" before calling the shell command.
$old_path = getcwd();
chdir('/my/path/');
$output = shell_exec('./script.sh var1 var2');
chdir($old_path);
Solution 2 - Php
Your shell_exec is executed by www-data user, from its directory. You can try
putenv("PATH=/home/user/bin/:" .$_ENV["PATH"]."");
Where your script is located in /home/user/bin Later on you can
$output = "<pre>".shell_exec("scriptname v1 v2")."</pre>";
echo $output;
To display the output of command. (Alternatively, without exporting path, try giving entire path of your script instead of just ./script.sh
Solution 3 - Php
Check if have not set a open_basedir in php.ini or .htaccess of domain what you use. That will jail you in directory of your domain and php will get only access to execute inside this directory.
