Linux Copy File Command [ cp Command Examples ]

How do I copy files under Linux operating systems? How do I make 2nd copy of a file on a Linux bash shell? How can I copies files and directories on a Linux?

To copy files and directories use the cp command under a Linux, UNIX-like, and BSD like operating systems. cp is the command entered in a Unix and 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

[donotprint][/donotprint]The syntax is as follows to copy files and directories using the cp command:



  • 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.

Note: You need to type the cp command at the dollar sign ($) prompt. This prompt means that the shell is ready to accept your typed commands. Do not type the dollar ($) sign. You need to open the Terminal app to use cp command on a Linux.

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

Sample outputs:

-rw-r--r--  1 veryv  wheel  20 Mar 20 17:42 file.doc
-rw-r--r--  1 veryv  wheel  20 Mar 20 17:43 newfile.doc

You can copy multiple files simultaneously into another directory. In this example, copy the files named main.c, demo.h and lib.c into a directory named backup:
$ cp main.c demo.h libc. backup
If backup is located in /home/project, enter:
$ cp main.c demo.h libc. /home/project backup

Copy a file to another directory

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

Verbose option

To see files as they are copied pass the -v option as follows to the cp command:

$ cp -v filename.txt filename.bak
$ cp -v foo.txt /tmp

Sample outputs:

foo.txt -> /tmp/foo.txt

Preserve file attributes

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 file.txt /dir1/dir2/
cp -p filename /path/to/new/location/myfile

This option force cp to preserve the following attributes of each source file in the copy as allowed by permissions:

  1. Modification time/date
  2. Access time
  3. File flags
  4. File mode
  5. User ID (UID)
  6. Group ID (GID)
  7. Access Control Lists (ACLs)
  8. Extended Attributes (EAs)

Copying all files

The star wildcard represents anything i.e. all files. To copy all the files in a directory to a new directory, enter:
$ cp * /home/tom/backup

The star wildcard represents anything whose name ends with the .doc extension. So, to copy all the document files (*.doc) in a directory to a new directory, enter:
$ cp *.doc /home/tom/backup

Recursive copy

To copy a directory, including all its files and subdirectories, to another directory, enter (copy directories recursively):
$ cp -R * /home/tom/backup

For more info see man pages: ls(1).
