How to copy a file from one folder to another folder in Linux

Question

Hello everyone,
Oracle forms 11g 11.1.2.0.0
OS: Oracle Linux
We use webutil to upload files to the application server from the client machine, and stores them in a folder named JOB_DOCS on the application server (This folder is created as a databse directory too). File types are JPEG, GIF, PDF, TXT, BMP, DOC, XLS etc...
At a later stage when the user tries to view the uploaded documents, this was not getting displayed on the screen
on our windows server, when the user clicks on the print button we copy the file from the JOB_DOCS folder to the forms\java folder using the below command
HOST('COPY ' ||d:\JOB_DOCS\test.pdf||' '||'c:\oracle\middleware\as\forms\java\test.pdf ,NO_SCREEN);
once the file is under the forms\java folder then it is getting displayed on the screen to print or save, and later we remove the file from forms\java folder.
But my problem here is, recently we have installed our application on Oracle Linux server, and we have JOB_DOCS folder there, and the users can upload files to this folder also. How can we copy the file test.pdf from JOB_DOCS to forms/java in linux?
And what could be the reson for the document cannot be accessed from the folder where it is saved? We tried giving folder permissions, adding the folder to PATH variable etc.

For copying and moving directories you can use the cp and mv commands just like you use them with files. Yeah, I know. If you've already tried to copy a directory with cp, you've probably noticed that cp just complains at you. Probably it says something like cp: omitting directory yadda yadda. You see, the cp command wants you to use the -r option if you want to copy a directory with its contents. The -r means "copy recursively":
$ cp -r dir1 dir2
The above creates a directory named dir2 whose contents will be identical to dir1. However, if dir2 already exists, nothing will be overwritten: the directory dir1 will be copied into the dir2 directory under the name dir2/dir1.
When renaming directories, you use the mv command exactly the same way as with files:
$ mv dir1 dir2
When dealing with directories, mv works a bit like cp does. If dir2 doesn't exist, the above will rename dir1 to dir2, but if dir2 exists, the directory dir1 will be moved into the dir2 directory under the name dir2/dir1.
