Q. How do I copy all the file including subdirectories from DVD disk mounted at /mnt/dvd to /home/tom at a shell prompt under CentOS Linux?

A. You need to use cp command to copy SOURCE to DESTINATION or multiple SOURCE(s) to a DIRECTORY. Gnu cp command has -a option which copy directories recursively while preserving the file attributes such as mode,ownership,timestamps and security contexts, if possible additional attributes such as links et all.

cp command syntax

Use the following syntax:
cp -a {/path/to/source} {/path/to/destination}

For example copy all files including subdirectories from /mnt/dvd/data to /home/tom/data, enter:
$ cp -a /mnt/dvd/data/* /home/tom/data
$ cp -av /mnt/dvd/data/* /home/tom/data

Recursively copy entire directories

Many other command (including cp) support -r or -R option for copying file recursively. For example scp secure network copy command:
$ scp -r *.cpp [email protected]:~
OR use cp command locally (instead of -a option):
$ cp -r *.cpp /path/to/dest

Q. FTP is insecure, how do I securely copy files across a network computer? My network has Windows and Linux systems.

A. You need to use Openssh client and server technology to copy between two more network computers. You can also find free ssh client tools. scp copies files between hosts on a network. It uses ssh for data transfer, and uses the same authentication and provides the same security as ssh.

Copy from Linux to Linux/UNIX system

Copy file called data.txt to Linux system (vivek is username):
$ scp data.txt [email protected]:/home/vivek

Copy more than two files:
$ scp data.txt pic.jpg [email protected]:/home/vivek
Copy /data directory and all files inside /data i.e. recursively copy entire directories:
$ scp -r /data [email protected]:/home/vivek

Copy from Windows to Linux/UNIX system

You can download any one of the following free Windows SCP client

Just install above client and follow on screen instructions.
