The tar command is one of the most useful tools in Linux systems. It helps you archive, compress, and extract files and directories. Whether you’re backing up data or transferring files, tar makes the process simple and efficient.<\/p>\n
In this tutorial, we\u2019ll look at how to use the tar command in Linux. Follow the steps below to archive, compress, extract, and manage files efficiently using the tar command.<\/p>\n
We use the tar command to compress and extract files from the command line. The basic syntax is shown below:<\/p>\n
tar [flags] destinationFileName sourceFileName<\/span><\/pre>\nThe tar command uses the following options to customize how it works:<\/p>\n
\n\n\nOption<\/span><\/th>\n Description<\/span><\/th>\n When to Use<\/span><\/th>\n<\/tr>\n<\/thead>\n\n\n-c<\/td>\n Create a new archive.<\/td>\n Use this when you want to make a new archive file.<\/td>\n<\/tr>\n \n-z<\/td>\n Use gzip compression.<\/td>\n Use this when you want the archive compressed with gzip.<\/td>\n<\/tr>\n \n-v<\/td>\n Provide verbose output.<\/td>\n The -v option shows details of the files being compressed or extracted.<\/td>\n<\/tr>\n \n-f<\/td>\n Archive file name.<\/td>\n Use this to specify the name of the archive file (e.g., -f backup.tar).<\/td>\n<\/tr>\n \n-x<\/td>\n Extract from an archive.<\/td>\n Use this when you need to extract files from an archive.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n1. Create a Tar Archive<\/strong><\/h4>\ntar -cvf backup.tar \/home\/user\/files\/<\/span><\/pre>\nExplanation:<\/p>\n
\n- -c: Creates a new archive<\/li>\n
- -v: Shows the progress in the terminal<\/li>\n
- -f: Specifies the name of the archive file<\/li>\n<\/ul>\n
This command creates an archive named backup.tar containing the contents of \/home\/user\/files\/.<\/p>\n
2. Compress an Archive Using Gzip<\/strong><\/h4>\ntar -czvf backup.tar.gz \/home\/user\/files\/<\/span><\/pre>\nExplanation:<\/p>\n
-z: Compresses the archive using gzip<\/p>\n
Other options are the same as above<\/p>\n
This creates a compressed archive named backup.tar.gz.<\/p>\n
3. Compress an Archive Using Bzip2<\/strong><\/h4>\ntar -cjvf backup.tar.bz2 \/home\/user\/files\/<\/span><\/pre>\nExplanation:<\/p>\n
-j: Compresses the archive using bzip2<\/p>\n
This creates a smaller archive using bzip2 compression.<\/p>\n
4. Extract a Tar Archive<\/strong><\/h4>\ntar -xvf backup.tar<\/span><\/pre>\nExplanation:<\/p>\n
-x: Extracts files from the archive<\/p>\n
This command extracts all files from backup.tar into the current directory.<\/p>\n
5. Extract a Gzip Compressed Archive<\/strong><\/h4>\ntar -xzvf backup.tar.gz<\/span><\/pre>\nExplanation:<\/p>\n
-z: Tells tar to use gzip to decompress<\/p>\n
This extracts files from a .tar.gz archive.<\/p>\n
6. Extract a Bzip2 Compressed Archive<\/strong><\/h4>\ntar -xjvf backup.tar.bz2<\/span><\/pre>\nExplanation:<\/p>\n
-j: Tells tar to use bzip2 to decompress<\/p>\n
This extracts files from a .tar.bz2 archive.<\/p>\n
7. View Contents of an Archive Without Extracting<\/strong><\/h4>\ntar -tvf backup.tar<\/span><\/pre>\nExplanation:<\/p>\n
-t: Lists the contents of the archive<\/p>\n
This shows you what\u2019s inside the archive without extracting it.<\/p>\n
8. Add a File to an Existing Archive<\/strong><\/p>\ntar -rvf backup.tar newfile.txt<\/span><\/pre>\nExplanation:<\/p>\n
-r: Appends files to an existing archive<\/p>\n
This adds newfile.txt to backup.tar. Note: This only works with uncompressed .tar files.<\/p>\n
9. Delete a File from an Archive<\/strong><\/h4>\ntar --delete -f backup.tar unwanted.txt<\/span><\/pre>\nExplanation:<\/p>\n
–delete: Removes a file from the archive<\/p>\n
This deletes unwanted.txt from backup.tar. This option may not work with compressed archives.<\/p>\n
10. Estimate Archive Size Before Creating<\/strong><\/h4>\ntar -cf - \/home\/user\/files\/ | wc -c<\/span><\/pre>\nExplanation:<\/p>\n
-cf -: Creates an archive and sends it to standard output
\nwc -c: Counts the number of bytes<\/p>\n
This helps you estimate how large the archive will be.<\/p>\n
