To unpack a .tgz file (also known as a "tarball") on a Linux system, you can use the tar command.
The tar command is a utility that is used to create, extract, and manipulate tar archives. It is commonly used to create backups and transfer files between systems.
To extract the contents of a .tgz file, you can use the following syntax:
tar -xzvf file.tgz
This will extract the contents of the file.tgz tarball and place the files in the current directory.
The -x option tells tar to extract the contents of the archive. The -z option tells tar to decompress the archive using gzip compression. The -v option enables verbose output, which will display the names of the files as they are extracted. The -f option specifies the name of the tarball file.
If you want to extract the contents of the .tgz file to a specific directory, you can use the -C option to specify the destination directory.
For example, to extract the contents of the file.tgz tarball to the /tmp directory, you can use the following command:
tar -xzvf file.tgz -C /tmp
This will extract the contents of the file.tgz tarball to the /tmp directory.
For more information about the tar command and its options, you can consult the documentation for your specific Linux system.
