Tar syntax:

Syntax: tar [primary option + secondary option] file or directory

When using this command, the primary option is required, which tells tar what to do, and the secondary option is secondary and optional.

Main options:

C create a new archive file. Select this option if the user wants to back up a directory or some files. It's the equivalent of packing.

X release the file from the archive file. It's the equivalent of unpacking.

T list the contents of the archive file to see which files have been backed up.

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.

Secondary options:

-z: does it also have the properties of gzip? That is, does it need to be compressed or decompressed with gzip? The general format is xx.tar.gz or xx. Tgz

-j: does it also have the properties of bzip2? That is, does it need to be compressed or decompressed with bzip2? The general format is xx.tar.bz2

-v: display files in the process of compression! This is commonly used.

-f: use the file name, please note that you should receive the file name immediately after f! Don't add any other parameters!

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

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

Example:

Example 1: package all the files in the entire / etc directory into / tmp/etc.tar

The code is as follows:

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