Introduction
In most cases, web-based file managers have certain limitations when it comes to file extraction. Or maybe you are using a VPS without any management panels at all, thus extracting archives will require you to connect via SSH and execute a certain command based on the archive type. The most common types of archives are .tar; .tar.gz and .zip, each having its own commands used for extraction or compression.
Extracting archives via SSH
First of all, you will need to navigate to the directory where your archive is located. For example, if your archive is located in public_html/files directory, the following command will do the trick:
cd public_html/files
How to extract .tar.gz
The following command will allow you to extract the contents of a .tar.gz archive:
tar -zxvf ArchiveName.tar.gz
You will see the visual output of all the files being extracted and will be able to execute commands again once the process finishes.
How to extract .tar
This type of compressed file can be extracted with the following command:
tar -xvf ArchiveName.tar
It will display the visual output of the process and will be completed once you are able to type commands again.
How to extract .zip
This command will take care of .zip file decompression:
unzip ArchiveName.zip
Once the process ends, commands will become executable again.
Creating archives via SSH
Now that we know how to extract all these archive types, we will also learn how to compress your files into any desired format.
How to create .tar.gz
The below-shown method will allow you to compress selected files into an archive:
tar -zcf NewArchive.tar.gz yourfile1.php yourfile2.php yourfile3.txt
If you intend to compress an entire directory, this will also do the trick:
tar -zcf NewArchive.tar.gz DirectoryName
As a rule of thumb, the archive generation finishes once commands become executable again in your terminal window.
How to create .tar
The syntax for creating .tar archives is very similar:
tar -zcf archive-name.tar.gz filename1.php filename2.php filename3.php
If you want to archive a directory, simply write the directory name instead of listing the files.
tar -zcf archive-name.tar.gz DirectoryName
Once you are able to type in a command again, it means that your archive has been created.
How to create .zip
This type of archive is even easier to create. The syntax is as follows:
zip archive-name.zip filename1.php filename2.php filename3.php
Compression of directories uses the same syntax as well:
zip archive-name DirectoryName
The screen will display a progress output and once it finishes it will allow you to write commands again.
Summary
Congratulations! By following this simple tutorial you now know how to create and extract .tar.gz; .tar; .zip archives using SSH.
