.tarファイルとは？

TAR (Tape Archive) is a Unix-originated format that bundles multiple files and directories into a single archive file without compression. TAR files preserve Unix file permissions, ownership, and directory structure. They are commonly combined with compression programs to create .tar.gz (gzip), .tar.bz2 (bzip2), or .tar.xz (xz) archives, which are the standard distribution format for Linux software and source code.
