This article mainly introduces the use of tar command package compression into linux file method. The content is more detailed, the article contains examples of the use of commands, I hope you can gain something from this article.

tar zcvf /data/abc.tgz --exclude=/etc/file1 exclude=/etc/file2 /etc --big package compression etc except file1 and file2 file big package compression file name is abc.tgz equivalent.tar.gz writing is different.

split -b 10M linux-5.1.4.tar.gz linux ---Cut files in 10M size with linux prefix to generate files Split files

CPIO command is a tool to package and restore files by redirecting them. It can extract files ending in ".cpio" or ".tar"
