When a new version of a base image is released - i.e., 3.9.6-slim -> 3.9.7-slim - you should pull the new image and update your running containers to get all the latest security patches. As you harden your application and Dockerfile(s) for production, you may want to explore using Alpine for the final image from a multi-stage build.Īlso, don't forget to update your base images regularly to improve security and boost performance.

You want to avoid having to continually update the Dockerfile to install necessary system-level dependencies when you add a new Python package. When in doubt, start with a *-slim flavor, especially in development mode, as you're building your application. Refer to The best Docker base image for your Python application and Using Alpine can make Python Docker builds 50× slower for more on why it's best to avoid using Alpine-based base images. As a result, you may end up having to build the binaries yourself, which can increase the image size (depending on the required system-level dependencies) and the build times (due to having to compile from the source). While the Alpine flavor, based on Alpine Linux, is the smallest, it can often lead to increased build times if you can't find compiled binaries that work with it. Most of these solutions make use of the cp command which cannot perform this feat on its own.Python 3.9.6-alpine3.14 f773016f760e 3 days ago 45.1MB Tee ~/directory1/file1 ~/directory2/file1 /dev/nul ConclusionĪs you have seen, there are many ways to copy a file to multiple directories.

Here is an example on how to perform this: The tee command allows you to copy one file to multiple destinations. Parallel cp -v /etc/nf ::: /directory1/, /directory2/ Using tee Let’s copy the file /etc/nf to /directory1/, /directory2/ : Parallel cp file_name ::: /directory1/ /directory2/ GNU parallel is a shell utility used for executing tasks or jobs in parallel over one or multiple machines. Read: How to find the largest files on Linux Using GNU parallel This however will copy the folder /full_path/folder to every sub-folder or sub-directory in your current location. This will copy the file /full_path/file.txt to all directories in your current path or location.įor dir in * do & cp -rf /full_path/folder “$dir” done Read: Linux directories explained Using loop in a shellĪnother solution would be to use a for loop within a one line shell as follows :įor dir in * do & cp /full_path/file.txt “$dir” done Read: How to use grep command in Linux Using findĪnother alternative to carrying out a copy to multiple destinations is to use the find command as follows :įind directory1 directory2 -exec cp file.txt \ This will prevent the destination file from being replaced. If the file to be copied has a large size and you do not want the destination file (if it exists) to be replaced, you might want to add the -n switch to the cp command in the single line above. In other words, the -i option (interactive) of the cp command cannot be used in conjunction with xargs. If the file to be copied exists already in one of the destination folders, the old file will be replaced without prompting the user.
So instead of executing two separate cp commands, we can now use one single command to perform the same task. as many target directories as provided in the input) where at each run, it appends the next directory path fed to it from the previous echo command to the end of the standard cp command. The xargs will execute the cp command two times (i.e. v : Allows verbose mode in order to display more details of the copy task n 1 : Instructs xargs to use one argument per command line at a time and forward to the cp command In the command above, target directories (directory_1,directory_2) are first echoed and then piped out (or fed) as input to the command xargs where:
To copy for instance file_1 into the folders directory_1, directory_2, we could proceed as follows:Įcho directory_1 directory_2 | xargs -n 1 cp file_1
The solution would be to use the xargs or GNU parallel commands. The most basic cp command syntax that is used to copy multiple files into one directory is the following :Ĭp /Documents/FileExample.txt /TextFiles/Ĭp command in linux How to copy one file to several directories ?Īs mentioned above, the cp command cannot be used to copy one file to multiple folders. You will see what additional commands and combinations are needed to pull this off. The obvious answer would be to use the cp command but this not is exactly correct since the cp command is rather used to copy several files into one directory. In this short article, you will learn how to copy one file into many directories.
