[SOLVED] How does Linux cp command determine the source and destination locations in command?
location: linuxquestions.com - date: April 14, 2011
When you run the following cp command in the BASH terminal, how does Linux know which files are the source and which are the destination when copying multiple files from one location to another?
cp /etc/services /etc/motd /etc/fstab /etc/hosts /home/fred/my_dir
How does Linux know that the services, motd, fstab, and hosts files are the source and the /home/fred/my_dir is the destination?
This question came up in a Linux class and I was not sure of the answer. I was thinking it is based on the source path entered ending with a file path and the destination being a directory, but was not sure.

Help with Linux Ubuntu 11.10 Permissions
location: ubuntuforums.com - date: February 17, 2012
I'm new in the forum, I searched for my issue and I didn't find anything. I hope somebody can help me.
I have a dedicated server running ubuntu 11.10 with php and mysql for now. Everything is good, the pages are served well and the connection to the database is good.
The problem comes when I try to generated a zip file for download from my admin area, I can't create neither folders nor files and it's driving me crazy because I don't want to apply 0777 to all the folders and files but I want to be able to generate my files, as well as use the php-gd library which also needs permissions to write.
My username is "aprintink", other than that I have "root" (I read that not everything is root) and the www-data which I suspect is the apache user.
How can I set my permissions to work with "aprintink" and allow "www-data" (if that is the user) to be able to work with files (reading, writing, executing)?
