I have a php artisan command that I created, and executed as bheng user

php /home/forge/site.com/artisan products:exportdiff --env=production

that export the file into my /files/product-exports/ directory

Also, I've already did

chmod -R 777 files/product-exports/

Result

The export part is working fine, I got the file exported as you can see in the image below

But I kept getting this

What is the different between white and green color code ?

Why does it place under the dot . ?

Does it mean anything at all ?

Question

Is this something that have to do with the permission ?

How would one go about and debug this further ?

I'm opening to any suggestions at this moment.

Any hints / suggestions / helps on this be will be much appreciated !

Update

As requested from @Tensibai

cd /home/forge/site.com/ && pwd && php /home/forge/site.com/artisan products:exportdiff --env=production

/home/forge/site.com

.

$source NOT exist !



  [Exception]

products:exportdiff

Update2

$source = /home/forge/site/files/product-exports/export1088_2016-11-23.csv

I've tried dd(file_exists($source));

It kept return bool(false)

Is it because of the way I check for file_exists ?
