How to use the tar command of Linux

This article will explain in detail how to use the tar command about Linux. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Tar command

[root@linux ~] # tar [- cxtzjvfpPN] files and directories.

Parameters:

-c: create a parameter instruction for a compressed file (meaning create)

-x: unlock a parameter instruction for a compressed file!

-t: check the files in tarfile!

Pay special attention to that only one c/x/t can exist in the issue of parameters! Cannot exist at the same time! Because it is impossible to compress and decompress at the same time.

-z: does it also have the properties of gzip? That is, is it necessary to use gzip compression?

-j: does it also have the properties of bzip2? That is, is it necessary to use bzip2 compression?

-v: display files in the process of compression! This is commonly used, but is not recommended in the background execution process!

-f: use the file name, please note that you should receive the file name immediately after f! No more parameters!

For example, using "tar-zcvfP tfile sfile" is the wrong way to write it. It should be written as "tar-zcvPf tfile sfile".

-p: use the original properties of the original file (the attributes will not change based on the user)

-P: absolute path can be used to compress!

-N: it is newer than the following date (yyyy/mm/dd) before it is packaged into the new file!

-- exclude FILE: do not package FILE in the process of compression!

Example 1:

Package all the files in the entire / etc directory into / tmp/etc.tar

[root@linux ~] # tar-cvf / tmp/etc.tar / etc
