In Unix- Linux , the name of the tar command is short for tape archiving, the storing of entire file systems onto magnetic tape, which is one use for the command. However, a more common use for tar is to simply combine a few files into a single file, for easy storage and distribution.
The tar command used to rip a collection of files and directories into highly compressed archive file commonly called tarball or tar, gzip and bzip in Unix – Linux. The tar is most widely used command to create compressed archive files and that can be moved easily from one disk to another disk or machine to machine.
14. Extract Group of Files using Wildcard
To extract a group of files we use wildcard based extracting. For example, to extract a group of all files whose pattern begins with .jpg from a tar, tar.gz and tar.bz2 archive file.
[root@cent /]# tar -xvf /root/emrepics.tar --wildcards '*.jpg' emre/emrepics1.jpg emre/emrepics2.jpg [root@cent /]# tar -zxvf /root/emrepics.tar.gz --wildcards '*.jpg' emre/emrepics1.jpg emre/emrepics2.jpg [root@cent /]# tar -jxvf /root/emrepics.tar.bz2 --wildcards '*.jpg' emre/emrepics1.jpg emre/emrepics2.jpg
