Running a bash script in PHP
 

Hello all. I am trying to run a bash script in php, but I am having trouble with the exec. I have all my permissions at 777 for now so I could see if that was it. I am running windows, but my code is actually on a Linux site -_-. Here is my code. I have tried changing the file name from Project to Project.sh, I had it like this earlier
exec("/home/knf0011/public_html/Project.sh);
exec('/home/knf0011/public_html/Project.sh');
exec('./home/knf0011/public_html/Project.sh');

Any help would be appreciated.

PHP ====================
if($e=="Sample.cpp")
{
exec("/home/knf0011/public_html/Project.sh, &$output");
echo $output . "<BR>";

}



BASH =====================

try:

exec("/home/knf0011/public_html/Project.sh", &$output);

That is close the quote after Project.sh and then have your $output as the second argument to exec.

That didnt work either....

Well I guess that you are going to have to provide more information. What actually happens? Do you get an error? Can you run a built in command from PHP?, Can you run a simpler script from PHP? Can you run the script from the shell?

nothing happens. The bash file is supposed to split up the text into different pieces and save them out. I actually have it set to echo whatever it does, but it just echos a black out.

What about the other questions I asked? Specifically, can you run the script from the shell? And can you run a built in command (that's a shell command such as ls)?

what you are trying to do in that bash script can be done in PHP itself.

Yes, the file runs in shell script by itself. If you can't tell with the bash, I'm taking a part a text file and saving off pieces of it. I am not good with php, so I wrote that part in bash.

Assuming that you have tried my other suggestions and drawn a blank, is the code being executed? The exec is wrapped in an if. Add echo statements to ensure that the code is being run.

I did this earlier

echo $e;
if($e=="Sample.cpp")
{
echo Sample.cpp;
exec("/home/knf0011/public_html/Project.sh, &$output");
echo $output . "<BR>";

}

and...

Please of you want help try to be a little less terse.

you can also try the following functions to help out...

file_exists()
is_executable()

try and echo the result from getcwd()

I wasn't being terse, I posted what I tried earlier...

Thank you all for your help. I didn't get it working, but I did something else instead for the project I did.

As well as posting what you tried, it is just as important (if not more so) to tell us what the result was, then it is possible for us to give you meaningful feedback and advice.
