PHP Exec Function Doesn't work with cd Ubuntu Command

[unemployment]

When I run

 

$dir = shell_exec('cd /var/www/trekeffect.com/trekeffect.com;pwd');

$this->log($dir);
//chdir('/trekeffect.com/trekeffect.com');
//shell_exec('cd /var/www/trekeffect.com/trekeffect.com', $output);
         
$test = shell_exec('pwd');
$this->log($test);

It logs:

2013-04-12 14:36:36-04:00 --- INFO: /var/www/trekeffect.com/trekeffect.com

2013-04-12 14:36:36-04:00 --- INFO: /var/www/deploy

 

It seems to be going back to the first deploy directory. Do you know why?

Wow.....very strange directories names

 

You don't have to execute shell_exec() every time, just put your logic into a simple string and execute it at once.

 

Something like:

<?php

$str = 'cd /var/www/trekeffect.com/trekeffect.com;';

$str .='pwd;';

$str .= 'ls -d'; // etc.....

//execute the string

$dir = shell_exec($str); 

echo $dir; 

Don't forget to separate the individual unix commands with semicolon

Ahh ok. I'll try that!

That works.  Thanks

shell_exec executes code in a new shell process. Meaning, if you call cd, it only changes directory for that process. Any subsequent calls to shell_exec will be executed from the original directory.

 

I don't see why you would be using php for this at all. Use bash, and your issues will go away.

Tony, I'm agree with you, in that case BASH is gonna be much more suitable and powerful than php.

Why don't you open a new thread instead extend this one? Nobody can charge you to create a new topic.
