We will look at how the file size is changed by the compression through several examples. There are stock images and some text files. I have assembled some files of different types in my Documents folder. Tar command examplesįor this article, I want to demonstrate some of the common methods for archiving and compressing files using tar. You may use the file command in Linux to know the type of a file. Your Unix system can typically identify files by their headers regardless of extension, but using the common naming scheme can help avoid confusion. It’s important to remember that extensions are not necessary on Linux and other Unix-based systems. I won’t go into these details in our examples, but I wanted to mention them. Further differences in the files result from structure and metadata. The popular 7z that has become fairly common in Windows environments also uses this algorithm. These tools primarily use the same compression algorithm, LZMA. txz, etc.: Tar also features built in support for xz, lzip, and more. It features a higher ratio of compression, but that increased shrinking power means it takes a bit longer to complete. tbz: This is the extension of an archive that has been compressed with Bz2. tgz: This is the extension of an archive that has been compressed with Gzip. It is only an archive and no compression is performed. Here are some of the common “tar files” you’ll find: I’ll show you how to do that later in this basic tar tutorial. While tar itself cannot compress files, you can use one of the common compression algorithms to compress the files while creating a tarball. Tarball is the common term used for a tar file. This is why you’ll often find software available in a ‘ tarball‘. A single file of 100 MB takes a lot less than transferring 100 files of 1 MB because of the file overhead. This saves network bandwidth, time and processing power while transferring the files. It creates a single file out of multiple files. Compression – The act of shrinking a larger file or files.Archiving – The act of storing multiple files as one file.Before we get too deep into the subject, let’s start things off with a little clarification. The tar command is important for Linux users to understand. Refresh the basics: Archive vs Compression Despite the nostalgic origin of the name, tar is very powerful and uses modern technologies to archive and compress files. What is tar? Tar stands for “ tape archive” and refers to a practice from the earlier days of computing when data was backed up to tapes. Tar -exclude='./folder' -exclude='./upload/folder2' cfzv archive.tar. Update existing tar file by adding todo.txt file to archive:Ĭreate a compressed archive of current directory but exclude certain directories: (Options: j = compress with bzip2, smaller file size but takes longer than -z) txt files in current directory:Įxtract files from gzip tar Archive :Ĭreate a compressed tar archive file using bzip2: (Options: x = extract, f = file, v = verbose)Ĭreate an uncompressed archive of all. r : updates or adds file or directory in already existing. u : archives and adds to an existing archive file t : displays or lists files in archived file Learn how to use tar in this quick article. Permissions are preserved and it supports many compression formats. Tar archives are not necessarily compressed but they can be. Tar archives combine multiple files and/or directories together into a single file. The command is also used to extract, maintain, or modify tar archives. The tar command is used to compress a group of files into an archive. Do you want to combine a bunch of files and directories into a single file? The tar command in Linux is what you're looking for!
