With compression level 5, xz produced the smallest archive at 29 MB, which was 69% smaller than pig z.xz used compression level 1 out of 9 for this In the same 4 seconds, xz compressed the file to just 48 MB, which was 49% smaller than pigz.Higher compression levels didn’t produce meaningfully smaller archives At compression level 7 out of 9, pigz compressed the 818 MB CSV file down to 95 MB in 4 seconds.pigz does this by default, xz because of the -T0 option Both archiving tools saturated the CPU in our tests.We compared xz to pigz, a gzip implementation that uses multithreading for faster compression and decompression. To test this claim, we used the same 818 MB CSV file, and the same computer with six CPU cores and hyperthreading, as we used to test gzip in Linux. Previously, we stated that xz creates smaller archives than gzip. Unlike xz, tar doesn’t delete the archive file after the extraction is completeĥ.Because of the v option, tar shows which files are extracted from the archive.tar does this automatically by inspecting the file and detecting the xz compression We don’t have to tell tar to decompress with xz.We decompress the file and extract its content into the current directory.Please note that we removed the J option here because –use-compress-program already sets the compression program.ĭecompressing a tar archive with xz is also a single step and identical to gzip (except for the different file extension): tar xvf Here, we specify the minimum compression level 1: tar cvf -use-compress-program='xz -1' *.csv We use this option to set the compression level, too. Tar allows setting the compression program through the –use-compress-program option. Which xz compression level does tar pick? It depends on our version of tar, but it probably is the default compression level 6. Unlike xz and gzip, tar doesn’t delete the input files after it creates the archive.Because of the v option, tar shows which files are added to the archive.The J option enables compression with xz.We compress all files with a csv extension in the current directory into the compressed archive,.To List the contents of a tar.gz file, -ztvf is used in tar command to view the contents of tar.gz files and to list the contents of a tar.bz2 file, -jtvf is used in tar command.

How to view stored files in an archive?īelow commands can be used to view files stored in an archive without extracting. $ tar -czvf /nfs/ -exclude='Downloads' /home/networkhunt/ 5. $ tar -zcvf –exclude=’dir1′ –exclude=’regex’ dir1įor example, exclude ~/Downloads/ directory: Sometimes we want to exclude certain files when creating a tarball. How to exclude directories and files when using tar To create and compress the archive file with the bzip2 compression, we have to use the option j with options cvf and use the file extension. Using bzip2 to compress and extract tar archives To extract the gzip tar file $ tar -xzvf 3. To compress multiple directories and files, execute: $ tar - czvf /home/networkhunt/data/ /home/networkhunt/pics/ /home/networkhunt/.accounting.db Say you want to compress an entire directory named /home/networkhunt/data/: $ tar -czvf /home/networkhunt/data/ gz with the archive file name to indicate that the gzip compression is used. To use the gzip utility to compress files before adding them to the archive, z will be used with the options cvf. Using gzip to compress and extract tar archives Process of Archiving files is completed and you can see the archived file with name file.tar by using ls command lsĢ. Tar: Removing leading `/' from member names To archive all the files in the folder ls => ls to view files in folderįile1.yaml file2.txt tar -cvf file.tar /root/linux/arch/ Archive and extract files using tar commandĮg. How to exclude directories and files using tarġ.

It compresses slower but provides a high compression ratio. bzip2 – use bzip2 to compress and extract files.It compresses faster but provides a low compression ratio. gzip – use gzip to compress and extract files.tar – archive and extract files using tar command.In this post, we will use two types of utilities to compress the files.

The tar command uses compression utilities such as the gzip and bzip2 to compress files before adding them to the archive. Archives are usually created for backup or transferring files. The tar command is one of the most commonly used commands in Linux to compress files to create archives.

Files are compressed before they are added to the archive. Most users use tar to compress files to save disk space or to save network bandwidth if they are transferring files over the network. This post shows how to compress and extract files in Linux.
