In Linux, tar is a command-line utility used for compression and archiving of files and directories. It is similar to the zip utility in Windows, but it offers more flexibility and control over the compression process.
In this article, we will cover the basics of how to tar a file in Linux. We will provide a detailed description of the tar command, illustrate its usage with code examples, and explain any related concepts or methods that may help to clarify the topic. By the end of this article, you will have a solid understanding of how to use tar to archive and compress files in Linux.
Understanding the Tar Command
The tar command is used to create and manipulate tar archives. It is a powerful tool that can be used for a variety of purposes, such as creating backups, archiving files for transfer, and compressing files for storage.
The basic syntax of the tar command is as follows:
tar [options] [archive name] [file(s) or folder(s)]The options are used to modify the behavior of the tar command, while the archive name specifies the name of the archive that will be created. Finally, the file(s) or folder(s) specify the files or folders that will be included in the archive.
Examples of Using the Tar Command
Creating an Archive
To create a tar archive, you must first decide on a name for the archive. In this example, we will create an archive called “myarchive.tar” that will contain a file called “myfile.txt”. Here is the command:
tar -cvf myarchive.tar myfile.txtThe options used in this command are as follows:
-c: create a new archive-v: verbose output (displays the names of the files as they are being added to the archive)-f: specify the name of the archive file
Extracting Files from an Archive
To extract files from an archive, you can use the following command:
tar -xvf myarchive.tarIn this command, the options used are as follows:
-x: extract files from the archive-v: verbose output (displays the names of the files as they are being extracted)-f: specify the name of the archive file
Adding Files to an Existing Archive
To add files to an existing archive, you can use the following command:
tar -rvf myarchive.tar myfile2.txtIn this command, the options used are as follows:
-r: append files to the end of an archive-v: verbose output (displays the names of the files as they are being added to the archive)-f: specify the name of the archive file
Compressing an Archive
To compress an archive, you can use the following command:
tar -czvf myarchive.tar.gz myfile.txtIn this command, the options used are as follows:
-c: create a new archive-z: compress the archive using gzip-v: verbose output (displays the names of the files as they are being added to the archive)-f: specify the name of the archive file
Extracting a Compressed Archive
To extract a compressed archive, you can use the following command:
tar -xzvf myarchive.tar.gzIn this command, the options used are as follows:
-x: extract files from the archive-z: uncompress the archive using gzip-v: verbose output (displays the names of the files as they are being extracted)-f: specify the name of the archive file
