Extract files

The extract command is not a specific command in Linux Ubuntu. However, if you are referring to extracting files from an archive, you can use different commands depending on the type of archive:

1. .tar archive: Use the tar command with the x flag followed by the name of the archive file. For example: tar -xvf file.tar will extract the contents of file.tar to the current directory.
2. .tar.gz or .tgz archive: Use the tar command with the xz flags followed by the name of the archive file. For example: tar -xvzf file.tar.gz will extract the contents of file.tar.gz to the current directory.
3. .zip archive: Use the unzip command followed by the name of the archive file. For example: unzip file.zip will extract the contents of file.zip to the current directory.
4. .rar archive: Use the unrar command followed by the name of the archive file. For example: unrar x file.rar will extract the contents of file.rar to the current directory.

Note that these commands may require additional options or flags depending on the specific archive file. You can refer to the manual pages (man) for each command for more information.
