ow do I copy files under Linux operating systems? How do I make 2nd copy of a file?

To copy files and directories use the cp command under Linux, UNIX, and BSD like operating systems. cp is the command entered in a Unix / Linux shell to copy a file from one place to another, possibly on a different filesystem. The original file remains unchanged, and the new file may have the same or a different name.

cp Command Syntax

The syntax is as follows to copy files and directories using the cp command:
 
 SOURCE DEST
 SOURCE DIRECTORY
 SOURCE1 SOURCE2 SOURCE3 SOURCEn DIRECTORY
 OPTION  SOURCE DEST
 OPTION  SOURCE DIRECTORY
 
Where,
  • In the first and second syntax you copy SOURCE file to DEST file or DIRECTORY.
  • In the third syntax you copy multiple SOURCE(s) (files) to DIRECTORY.

Linux Copy File Examples

To make a copy of a file called file.doc in the current directory as newfile.doc, enter:
$ cp file.doc newfile.doc
$ ls -l *.doc

To copy a file in your current directory into another directory, enter:
$ cp filename /tmp
$ ls /tmp/filename
$ cd /tmp
$ ls
$ rm filename

To copy a file to a new file and preserve the modification date, time, and access control list associated with the source file, enter:
$ cp -p filename /path/to/new/location/myfile
To copy all the files in a directory to a new directory, enter:
$ cp * /home/tom/backup
To copy a directory, including all its files and subdirectories, to another directory, enter (copy directories recursively):
$ cp -R * /home/tom/backup

actually this is wrong. It doesn’t copy subdirectories
To copy all the files in a directory to a new directory, enter:
$ cp * /home/tom/backup

If you need helping with the copy command (CP)….
At the command line (CLI)… type:
cp –help
This will display the list of switches used on how to copy. It also shows the format on how to copy single, multiple files and directories.

How does this command know what directory you are saving the newly copied file too? Where is that in the below example?
$ cp filename /tmp
$ ls /tmp/filename
$ cd /tmp
$ ls
$ rm filename
