Download And Extract Tar.gz

[Carolina Bornman]

Ireceived a huge .tar.gz file from a client that contains about 800 mb of image files (when uncompressed.) Our hosting company's ftp is seriously slow, so extracting all the files locally and sending them up via ftp isn't practical. I was able to ftp the .tar.gz file to our hosting site, but when I ssh into my directory and try using unzip, it gives me this error:

Just like the more familiar .zip files, .tar files compress large files into a single package, making it easier to store and send them through email, servers, and so on. As a result, it has become a common file extension for many open-source software packages and other resources.

But with .zip being the easier of the two to use, why use .tar in the first place? The next section shows how .tar comes with a few extra features that make it the better compression format for certain files and applications.

Where .zip files consist of many individually compressed files, .tar files are compressed as a single package, leaving its files uncompressed. In other words, .zip files are a collection of compressed files, while .tar files are a compressed collection of files.

It depends. For sending and storing, both .zip and .tar.gz files allows you to send relatively large packages as a single file. However, there are some pretty major differences when it comes to accessing data within the files and the compression efficiency.

As we see later, different compression utilities may require different methods for extracting and unzipping files. Though we mostly focus on .tar.gz files, check out the end of the article for some quick tips on extracting .tar files in other formats.

Most Linux distributions and macOS include built-in tools for zipping and unzipping .tar and .tar.gz files. While the tar utility is enough for most purposes, you need the gzip utility to create .tar.gz files.

Note that this command will throw an error unless you specify the exact filename listed in the .tar file. As we cover more in the next section, you can verify file names by listing contents with the tar -tf filename.tar.gz command.

You can create your own compressed .tar files using compression utilities such as gzip. Gzip is one of the most popular and available options, especially since it comes built in to most Linux distributions and macOS.

If you want to keep the original file after compression, there are two options. The first is the -k option, and the other uses the -c option to output the compressed file to a different file, preserving the original.

With the command prompt open, use the appropriate commands to change the current working directory (cd) to the location of the .tar.gz file you want to unzip. Alternatively, you can also specify a source and destination file path when using the tar utility.

While there are many tools to choose from, the most popular include 7-Zip and WinZip. While slightly different, they are quite lightweight and offer a much simpler alternative to using the command line.

Solution: Find a new copy of the .tar.gz file, or simply extract it as a .tar file using tar -xf filename.tar instead. If this command also throws an error, the next solution might help.

While every tar.gz file is a .tar archive, not every .gz is a .tar file. The .gz extension represents the gzip compression format, which can be applied to almost any file format to compress data and save space.

Though both .zip and .tar.gz archive and compress files, they do so in different ways. Where .zip archives and compresses individual files, .tar only archives individual files, leaving a separate compression format such as .gz (gzip) to compress all of them as a single file/archive. In other words, .zip is a collection of compressed files, while .tar.gz is a compressed collection of files.

Yes. Since .tar.gz compresses multiple files all at once, it can take advantage of similarities between individual files to save on space. Generally speaking, a collection of files archived and compressed as a .tar.gz are more space-efficient (i.e., smaller) than the same collection compressed as a .zip.

Entering [.inline-code]tar unzip to specific folder[.inline-code] in the AI Command Suggestions will prompt a [.inline-code]tar[.inline-code] command that can then quickly be inserted into your shell by doing [.inline-code]CMD+ENTER[.inline-code].

Note that some versions of the [.inline-code]tar[.inline-code] command, particularly on macOS, might not support the [.inline-code]--wildcards[.inline-code] flag. In such cases, you can directly specify the globbing pattern after the command as follows:

To download and extract a [.inline-code]tar.gz[.inline-code] file with Wget, you can redirect the output of the [.inline-code]wget[.inline-code] command to the [.inline-code]tar[.inline-code] command using the pipe operator as follows:

If you find difficulties working with command-line, know that you can also use a desktop app or online alternative to extract a [.inline-code]tar.gz[.inline-code] file. On the desktop, you can use apps like 7 zip or WinRAR. In the browser, you can use websites like ezyZip.

Several operations involving multiple files might store and compress the result in a .tar.gz format. It's an alternative to the ubiquitous ZIP format and popular among backup and archiving tools, especially in Unix or Linux operating systems.

A .tar.gz or .tgz file is a compressed archive file format that is a combination of two other archive formats, namely TAR (tape archive) and GZIP. The TAR format is used to store multiple files into one archive, while GZIP is used to compress the data in the archive to reduce its size. The .tgz file format is typically used on Unix and Linux operating systems, but can also be opened on other platforms, including Windows and macOS, with the help of specialized software.

To extract the contents of a .tgz file, you can use a tool such as tar (on Unix and Linux) or a file compression utility like 7-Zip or WinRAR (on Windows). Once the file has been extracted, you will have access to all of the files and folders contained within the archive.

To extract a .tar.gz file on Windows, you will need a file compression tool that supports this format. There are many such tools available, with a friendly graphical user interface, including 7-Zip (open source) and WinRAR (free trial). Windows 10 also includes a build in tar utility that can be used via the command line / terminal.

I have a file (reviews_dataset.tar.gz) that contains many files which contains data. I am required to extract the files in this archive and then perform some basic commands on the file. So far I have created a directory named (CW) and found a command tar zxvf fileNameHere.tgz but when I run this it of course cannot find my file as I have not "downloaded it" into my directory yet? How do I get this file into my directory so that I can then extract it? Sorry if this is poorly worded I am extremely new to this.

so I created a tar.gz file under openwrt and amd having issues getting the syntax correct to extract the tar.gz file while excluding/not extracting certain files from the tar.gz. No matter how I format the syntax it either gives and error or extracts the contents I told it to exclude. Sometimes it will even say the specified file I am telling it to exclude (-X) is not inside the tar file when in fact it is. Can someone please clarify the correct syntax for tar to exclude files.

im trying to install themes and when i download the file i need to extract it and unless i switch to root in terminal i dont have permission to extract it to /usr/share/themes. so what code do i need to use tto exract files in terminal?

Also heres a handy little function that makes it easy to extract files from CLI if you cant remember the cmds. I have it in my /etc/bash.bashrc so it works for all users. Type "extract foo.bar" to extract. You might also need to install unzip,unrar or others.

I need to open a file that sadly is only available in the .tar.gz file format and I am using Windows 7. I can unzip the file using 7-zip but after that I still have a .tar file that I can't open in Windows.

The 7-zip package comes with a command-line tool called 7z.exe that can pipe to and from stdin (-si) & stdout (-so). So the following line will do the extractraction in one step with no intermediary file (-ttar tells 7-zip that we're piping in a tar stream).

I have now tried this a few different ways with a couple different versions of the artifact and I do not get repeatable results. I have gotten the tarball to extract a couple of times, but after clearing my cache and the target directory and trying it again, I get the same error.

After running with -s and getting the stack trace I think I have figured out what the problem is. I must have missed something earlier when I ran it with the -d flag. I can fix the issue reliably by deleting the build/tmp/expandedArchives folder AND the target folder.

I think the copy task may be running into trouble because I am expanding the flexSDK archive outside of the root project folder and the up-to-date check is not skipping the task execution. It seems to be running into an issue over-writing or accessing a file in the expandedArchives tmp folder I am not sure if this is during the actual copy or if it is happening when it is checking the up-to-date status.

If I understand your objection correctly, you might be missing the point. The suggestion is that 7-zip be enhanced with an optional switch, not that gzip and tar be changed. There would be no impact on established configurations of 7-ZIp or scripts using gzip or tar.

Just for the record, DJTAR from DJGPP (or DJTARNT associated with old Win32 Emacs releases) can unpack .tar.gz (or .tar.Z or "Deflate" .zip) all in one step without using other utils. DJGPP 2.04 beta's DJTAR can also handle .tar.bz2, but I'm fairly sure the pre-compiled Win32 builds (from 1999?) don't support this.

+1 from me.

Extracting tar.gz-files in two manual steps instead of one is for me the main inconvenience compared to WinRAR, which I used before I installed 7-zip recently.

Currently I mostly use the file explorer right-click menu UI in Windows.
