How To Uncompress Separated TGZ Files

Ubuntu 14

In the world of data management, you may often find yourself dealing with compressed files. One such file type is the TGZ file, which is a GZIP compressed tar archive. In some cases, these TGZ files may be separated into multiple parts. This article will guide you through the process of how to uncompress separated TGZ files.

Quick Answer

To uncompress separated TGZ files, first combine all the parts into a single file using the cat command. Then, use the tar command to extract the contents of the combined file.

Understanding TGZ Files

Before we delve into the process, let’s understand what TGZ files are. TGZ files, also known as .tar.gz files, are a collection of files bundled together and compressed using the GZIP compression algorithm. They are commonly used in systems that use Linux or Unix. If a TGZ file is too large, it might be split into multiple parts. These parts need to be combined before they can be uncompressed.

Combining the Parts

The first step in uncompressing separated TGZ files is to combine all the parts into a single file. Make sure all the parts of the compressed file are in the same directory. Then, use the cat command to combine them. The cat command in Unix or Linux is used to concatenate and display file content. Here’s an example:

cat OVM_EL5U3_X86_EBIZ12.1.1_DB_VIS_PVM.tgz.* > combined.tgz

In this command, OVM_EL5U3_X86_EBIZ12.1.1_DB_VIS_PVM.tgz.* represents all the parts of the original TGZ file. The > operator is used to redirect the output of the command to combined.tgz. As a result, all the parts are concatenated into a single file named combined.tgz.

Uncompressing the Combined File

Once you have a single TGZ file, you can use the tar command to extract its contents. The tar command is used to manipulate tar archives in Unix or Linux. It can create, extract, or list the contents of archives. Here’s how you can use it:

tar -zxvf combined.tgz

In this command, -z is used to uncompress the archive using gzip, -x to extract the files from the archive, -v to display the progress in the terminal, and -f to specify the name of the archive. combined.tgz is the name of the file we are extracting.

Troubleshooting

If you encounter any errors during this process, such as “not in gzip format” or “Child returned status 1”, it could indicate that the file parts are not in the correct format, or there might be an issue with the file itself. Here are a few troubleshooting steps:

Checking the File Type

You can use the file command to check the type of the file. This command provides information about the file type. Here’s how you can use it:

file OVM_EL5U3_X86_EBIZ12.1.1_DB_VIS_PVM.tgz.1

If the file type is not as expected, you need to ensure that all the parts are present and in the correct order. You may need to rename or reorganize the files accordingly.

Dealing with Corrupted Files

If the file type is correct but you still encounter errors, it’s possible that the file is corrupted or incomplete. In such cases, you may need to obtain a new copy of the file.

Conclusion

Uncompressing separated TGZ files might seem like a daunting task, but with the right commands and understanding of the process, it becomes straightforward. Remember to adjust the file names and commands according to your specific situation. Always ensure that you have a backup of your data to avoid any loss during the uncompression process. Happy uncompressing!

What is the purpose of compressing files into TGZ format?

Compressing files into TGZ format helps reduce their size, making it easier to store and transfer large amounts of data.

How do I know if a TGZ file is separated into multiple parts?

The presence of multiple files with the same name and different extensions, such as .tgz.1, .tgz.2, etc., indicates that the TGZ file is separated into multiple parts.

Can I uncompress a TGZ file without combining its separated parts?

No, you must combine all the parts of a separated TGZ file before uncompressing it.

What if I encounter errors while combining the parts of a TGZ file?

If you encounter errors, it could indicate that the file parts are not in the correct format or that there is an issue with the file itself. Make sure all parts are present and in the correct order, and consider obtaining a new copy if the issue persists.

How can I check the type of a file using the command line?

You can use the file command followed by the file name to check the type of a file. For example: file OVM_EL5U3_X86_EBIZ12.1.1_DB_VIS_PVM.tgz.1.
