Linux copy from folder

How can I copy the contents of a folder to another folder in a different directory using terminal?

I am trying to copy the contents of a folder to another folder in a different directory using terminal. Would somebody be able to provide me an example of the command line syntax required to achieve this?

You can copy the content of a folder /source to another existing folder /dest with the command

The -a option is an improved recursive option, that preserve all file attributes, and also preserve symlinks.

The . at end of the source path is a specific cp syntax that allow to copy all files and folders, included hidden ones.

@DylanValade: -a already implies —preserve=all , that is wider than -p = —preserve=mode,ownership,timestamps .

@BennyNeugebauer: scp is used to copy over a network (through ssh ) and only encrypts the communication channel, not the files on the destination filesystem.

«The . at end of the source path is a specific cp syntax that allow to copy all files and folders, included hidden ones.», this is not related to cp, but related to bash. The dot means «this location» and avoids the use of bash globbing, where by default files/directories starting with a . are not expanded.

Can someone explain the need behind use of mypath/. instead of the existing bash wildcard expansion character, mypath/* ?

rsync -a source/ destination 

The advantages of rsync are:

1. After the initial sync, it will then copy only the files that have changed.
2. You can use it over a network, convenient for files in $HOME, especially config files.

This will not copy hidden files, since bash expands * only to non-hidden file. The solution by @Joschua is safer.

If it’s a big folder you may wish to use one of these options to view progress while it’s copying askubuntu.com/questions/609303/…

Lets say you have a folder called folder1 in your ~ , inside folder1 is 1 file called file1 and 2 folders called sub1 and sub2 each with other files and folders inside them.

To copy all the contents of ~/folder1 to ~/new_folder1 you would use

new_folder1 would then contain all the files and folders from folder1 .

cp is the command to copy using a terminal, -r makes it recursively (so, current directory + further directories inside current) ~/folder1 is the origin folder, ~/new_folder1 is the destination folder for the files/folders inside the origin.

Thank you Bruno! It helped me to understand the syntax, though I had to change it a bit(removing ~ sign). Maybe because the destination folder was in /opt, which resides in another file system. And thank you Portablejim to remember the hidden file thing!

The trailing period is important. Without it, sometimes it may create a new subdirectory ~/new_folder1/folder1 instead of copying the contents over.

@Alex78191 [root@ home]# mkdir food [root@ home]# cd food/ [root@ food]# mkdir .fruit [root@ food]# mkdir veggies [root@ food]# touch veggies/carrots [root@ food]# touch .fruit/apple [root@ food]# ls * carrots [root@ food]#

Simple example.

Copy the directory dir_1 and its contents (files) into directory dir_2:

cp -r ./dir_1 ./dir_2 # or cp -r ./dir_1/ ./dir_2/ # Results in: ./dir_2/dir_1/_files_ 

Copy only the contents (files) of dir_1 into directory dir_2:

cp -r ./dir_1/. ./dir_2 # or cp -r ./dir_1/. ./dir_2/ # Results in: ./dir_2/_files_ 

_files_ is a placeholder for the actual files located in the directory.

cp is a Linux command for copying files and directories. The syntax is as follows:

cp source destination cp dir1 dir2 cp -option source destination cp -option1 -option2 source destination 

In this example copy /home/vivek/letters folder and all its files to /usb/backup directory:

cp -avr /home/vivek/letters /usb/backup 

-a : Preserve the specified attributes such as directory an file mode, ownership, timestamps, if possible additional attributes: context, links, xattr, all.

-v : Explain what is being done.

-r : Copy directories recursively. Example

Copy a folder called /tmp/conf to /tmp/backup:

This code with Flag «-R» copies perfectly all the contents of «folder1» to existing «folder2»:

Flag «-R» copies symbolic links as well but Flag «-r» skips symbolic links so Flag «-R» is better than Flag «-r».

-R, --dereference-recursive For each directory operand, read and process all files in that directory, recursively, following all symbolic links. 

-r, --recursive For each directory operand, read and process all files in that directory, recursively. Follow symbolic links on the command line, but skip symlinks that are encountered recursively. Note that if no file operand is given, grep searches the working directory. This is the same as the ‘--directories=recurse’ option.

How to Copy All Files from a Directory to another Directory in Linux

Copying the file or folder means creating a new file having duplicate content as in the existing file.

Sometimes, we need to copy the files or folders rather than having a backup program. The files can be copied with the same name, or you can change the name as well.

Copying a file, folder, or directory is a simple and basic task in the Linux operating system. Rename, delete or copy commands are used as daily purpose operations while working with the command-line interface.

Although there are multiple commands to copying the files, the “cp” and “rsync” command are widely used simplest approaches.

How to Copy Files with “cp” Command in Linux:

The “cp” command is one of the commonly used commands to perform the copy operation. You can copy files or folders from source to destination, i-e, one directory through this command.

The syntax of the “cp” command is:

Let’s take a look at an example to understand the “cp” command tool better.

In the home directory, create a “temp” folder with the text file named “text_file1.txt” and add random content to it.

Copy a file with the same name:

To copy a “text_file1.txt” file directory with the same name, open the terminal and type the mentioned “cp” command with the right path.

Get the folder’s path by right-clicking on the file and navigate to the “Properties” option (it is the easy way to get the path link).

A dialogue box will open with the complete path of a text file:

Use this path with the “cp” command to copy file:

This command will copy the “text_file1.txt” file to the “temp2” folder.

To verify it, type the “ls” command in the terminal:

Copy a file with a different name:

To copy the file in the current working directory with the different name, type the following “cp” command with file location:

Verify it using the “ls” command”:

Copy Multiple Files with “cp” Command:

To copy multiple files with the “cp” command, navigate the terminal to the directory where files are saved and then run the “cp” command with the file names you want to copy and the destination path.

$ cp text_file1.txt text_file2.txt text_file3.txt / home / wardah / temp2

Run the mentioned command to verify if files are copied successfully:

Above mentioned scenarios are how to copy a single or selected file in a directory. Now, use the wildcard character (*) to copy present files of one directory to any other specific directory.

Run the “ls” command to check how many files exist in the temp directory:

Instead of mentioning all file names in the terminal, use the wildcard (*) with the directory path to copy all the files into destination:

Now, run the “ls” command again to check if all files are copied in the “temp2” directory:

How to Copy files with the “rsync” command in Linux:

The “rsync” command is another versatile Linux tool to synchronize and copy files and directories locally as well as remotely.

The syntax of the “rsync” command is to copy files is:

It is a pre-built tool in many Linux distribution. However, if you don’t get it on your system, install it by executing the following command:

To copy a file from one place to another, run the following command:

To copy all the directory files to another location, the command would be:

(The “-a” with the “rsync” command is used to copy directories recursively)

Here are the two concepts:

If you add a trailing slash (/) with the path, it will copy the content of the source directory to the destination directory, just like shown in the image:

But, if you don’t add it, it will copy the source directory inside the destination directory, like:

The above command will copy a “dir1” directory to the “dir2” directory.

Conclusion:

Copying a file or directory is the basic command one can operate. One can use it multiple times while using Linux operating system.

This guide has seen the two simplest approaches, the “cp” command and the “rsync” command. Using these commands, we have learned how to copy a single file, multiple files, and even copy one directory to another.

How do I create a copy of a directory in Unix/Linux? [closed]

I want to recursively create a copy of a directory and all its contents (e.g. files and subdirectories).

The option you’re looking for is -R .

cp -R path_to_source path_to_destination/ 

• If destination doesn’t exist, it will be created.
• -R means copy directories recursively . You can also use -r since it’s case-insensitive.
• To copy everything inside the source folder (symlinks, hidden files) without copying the source folder itself use -a flag along with trailing /. in the source (as per @muni764 ‘s / @Anton Krug ‘s comment):

cp -a path_to_source/. path_to_destination/ 

i wonder why this exact command in dockerfile copies all source directory files into destination, instead of copying just whole directory.

I believe the ‘/’ on the end makes a difference and that might account for your experience. If the source includes the trailing slash it will copy what is in the directory only. If it does not include the trailing slash, it will copy the directory as well and then the contents inside of it. My memory is this behavior varies by command and maybe event by OS a bit. Here’s a reference with more info.

I would say if you don’t want to include the source and you want to make sure everything is copied (symlinks, hidden files) without copying the source parent folder is to use -ra source/. destination. This will make sure the content of the folder is copied, but not the parent folder itself, which is sometimes handy. And the difference is the /.

Note the importance of «Slash dot» on your source in cp -r src/. dest I know it is mentioned but I still seem to miss it every time.

You are looking for the cp command. You need to change directories so that you are outside of the directory you are trying to copy.

If the directory you’re copying is called dir1 and you want to copy it to your /home/Pictures folder:

Linux is case-sensitive and also needs the / after each directory to know that it isn’t a file. ~ is a special character in the terminal that automatically evaluates to the current user’s home directory. If you need to know what directory you are in, use the command pwd .

When you don’t know how to use a Linux command, there is a manual page that you can refer to by typing:

Also, to auto complete long file paths when typing in the terminal, you can hit Tab after you’ve started typing the path and you will either be presented with choices, or it will insert the remaining part of the path.

There is an important distinction between Linux and Unix in the answer because for Linux (GNU and BusyBox) -R , -r , and —recursive are all equivalent, as mentioned in this answer. For portability, i.e. POSIX compliance, you would want to use -R because of some implementation-dependent differences with -r . It’s important to read the man pages to know any idiosyncrasies that may arise (this is a good use case to show why POSIX standards are useful).
