You should then see the files that were added to your tarball.Īlso, if you type in ls -la again, you’ll see your new file: Type in this command: tar -cvf ourfiles.tar *.txt We have the tar command and add our arguments (-cvf), the name of the archive to create, and *.txt for all text files. Now, let’s create a tarball named ourfiles.tar. Type in ls -la to confirm they are in your directory: We’ll create four empty files: touch file1.txt file2.txt file3.txt file4.txt If they’re bundled and compressed, they’re named .Īnother extension you may see is filename.tgz, which is just shorthand for. When the files are uncompressed, they’re usually named something like filename.tar. You take a set of files and bundle them together, and compress them into a. What are tarballs? They’re a group of files bundled together in a single file. How do we install software from tarballs?.How do we extract files from a tarball?.Now we’re going to look at something that trips up many beginners: tarballs. For more tar command examples, see my Linux tar command examples and tutorial.In the last article in our series, Linux Commands You Need to know Part 2: Working with Files we learned how to work with files on our filesystem. I hope this short tutorial on how to extract (un-tar) a file from a tar archive has been helpful. How to extract (un-tar) a file from a tar archive In this case my tar archive was named drupalsite.tgz, and I wanted to extract the "marinelli" subdirectory of that archive, which, if you're familiar with Drupal, is found in the "sites/all/themes" folder.Įxtracting this tar directory like this actually extracts the marinelli folder under the sites/all/themes directory on my computer, so I end up with aįolder, filled with all of its subdirectories, but no other subdirectories under the top level "sites" directory are extracted. One more note before I go: I just wanted to extract one directory from a much larger tar archive, and to extract that directory from my tgz file I used this tar command: Extract (un-tar) a directory from a tar archive Unless you're making backups on your own Linux system, absolute paths are usually a no-no, and even if you are making your own backups, they're usually a no-no, as they don't give you much flexibility during the restore (un-tar, extract) operation. For instance, if a file in the tar archive has this path:Īnd I then extract that file from the tar archive, it will clobber the current. ![]() By "absolute path", I mean any file whose path begins with the root directory "/". One thing to be careful about here is to see if files are in the archive with an absolute path. However, if the file was in a sub-directory named bar, you'd want to specify your un-tar command like this: For instance, if your file is named "foo" and it's in the root directory of the archive, you'd use this command: ![]() The secret here is that you need to specify your filename just as it is in the tar archive. Now, to answer the question, if you want to un-tar one file named "my-desired-file" from a tar archive named "my-archive.tgz", and assuming the archive is compressed as most are these days, you'd use a command like this: Tar extract FAQ: How do I extract one file (or multiple files) from a tar archive without extracting the entire archive (i.e., how do I un-tar files from a tar archive)? Extract all files from a tar archiveįirst, if you really want to extract a tar archive completely (un-tar a tar archive), I've written about that before in my How to extract a tar archive tutorial and my Linux tar command examples, so I won't repeat those tutorials much, other than to say that this command is common to un-tar an uncompressed tar archive:Īnd this command is common to un-tar a compressed tar archive:Įxtract (un-tar) one file from a tar archive ![]()
