We then delete the new/test2.txt file, extract it and restore it, then cat the contents to show that the copy from the archive was indeed ~]# echo 'new text' > ~]# tar -uf archive.tar ~]# rm -f ~]# tar -xf ~]# cat new/test2.txt

EXAMPLES OF TAR COMPRESS UPDATE

In this example we append “new text” to new/test2.txt and then update the archive.tar file with this new file. We can update the existing files inside a tar file with newer files on the file system with the -u option, it will only append files that are newer than the copy within the archive file. Now even if we completely delete the new directory, when we extract the contents of archive.tar the directory will be recreated from the ~]# rm -rf ~]# tar -xf ~]# ls -l new/ Note that this has also copied the directory path, as shown in the output when we list the contents of the tar file. In this example, we add our previously extracted test2.txt file back into the ~]# tar -f archive.tar -r ~]# tar -tf archive.tar We can add additional files into an existing tar file with the -r option which will append files to the archive. In the below example we remove the test2.txt file then list the contents of archive.tar which now only has test1.txt left ~]# tar -f archive.tar -delete ~]# tar -tf archive.tar

We can also remove files from within the tar file with the -delete option. This way we can visually see what has been added into the tar file without the need to list the contents with -t after the fact. Verbose output will print the files and directories that are being added to an archive or extracted from an ~]# tar -cvf archive.tar test1.txt test2.txt The -v option for verbose can be added to the tar command which will display useful additional information which may be useful when troubleshooting problems. We can also extract multiple files at once this way by adding more onto the end of the command. In this example we first remove the files we extracted from the last example, then specifically extract just the test2.txt file ~]# rm -f ~]# tar -xf archive.tar -C new/ ~]# ls -l new/ Rather than extracting all contents of the tar file which is the default, we can specify a particular file to extract. Rather than first cd to the destination directory, we can use the -C option which will change to the directory specified when performing the extraction for ~]# mkdir ~]# tar -xf archive.tar -C ~]# ls -l new/ Extract Tar File To Specific Directoryīy default tar will extract to the current working directory which may not always be what we want. tar file, it will remain in place after extracting files from it. This is ~]# > ~]# cat ~]# tar -xf ~]# cat test2.txt In this example, we show the contents of the original test2.txt file, wipe it clean, then extract the contents of archive.tar confirming that the contents of test2.txt have been returned from the copy in the ~]# cat test2.txt We can extract all contents of a tar file with the -x option. Note that we also need the -f option to specify the tar file to run ~]# tar -tf archive.tar We can list the contents within a tar file with the -t option. tar extension, however we use it here to allow us to easily see what the file is. The original files still exist after being added to the archive, they are not removed by default. 1 root root 10240 Sep 2 12:26 archive.tar The -c option is used to create a new archive file, while the -f option is used to specify the archive file to use (in this case, ~]# tar -cf archive.tar test1.txt ~]# ls -la In its most simplest form, the tar command can be used to copy multiple files into a.
