Originally created by @benoon on GitHub (Feb 4, 2011).

so i wrote some simple python script to check it with exec('python26 simple.py') and it runs without problems, however when i try exec('python26 youtube-dl') it doesn' run.
when i run my script on shell from command line it runs. when i do that from the browser it is not runned.

why?

Who knows? "It doesn't run" couldn't be less specific. I doubt this is a problem with youtube-dl, though, so I'm closing the issue.

$ php <<EOF
> <?php exec('/home/rg3/bin/youtube-dl'); ?>
> EOF
Usage: youtube-dl [options] url...

youtube-dl: error: you must provide at least one URL

I think it's important.
user nobody can run other python scripts so why I had to use sudo for youtube-dl ?
Would be great to know that.
THX for great project!

You'd need to provide much more information if you want any type of help, like the exit status of the command, the standard output, standard error...

I know for a fact many people use youtube-dl from PHP, so it's probably a mistake you're making. I'm not an expert in PHP at all.

I would give you more info but please write how I should do this.

When I do this:

passthru('youtube-dl -h > log.txt');

I get empty log.txt file

When I run as root

passthru('sudo -u root youtube-dl -h > log.txt');

I get all the help as it should give.

So when I run this script as user 'nobody' which is default apache user it just gives no error, nothing. Is not executed at all.

It's very strange coz other python script I can run without any problems as nobody.
That's why I was asking if there are any other linux commands in your script which may not go when you have no priviliges. It could be good to give some info that for some linux commands you need to have special permissions.

Thats why I thought it's maybe not a bug but something which can save time to others later.

There are no "Linux commands", or shell commands, in youtube-dl. I don't know how to help you here other than checking the basics like file path, permissions, owner, etc.

Ok, with sudo I can use it without any problems so if anybody find the same problem - USE SUDO !

thanks for your answers.

Bad advice, IMHO, but whatever floats your boat.
