Tar decompression command details

For example, if you use "tar-zcvfPtfilesfile", you must write it as "tar-zcvPftfilesfi ".

Format: tar option file directory list

Function: Package and back up the file directory.

Option:

-C create a new archive file

-R: append an object to the end of the archive object

-X solve the file from the archive file

-O unlocks the file to the standard output

-V output related information during processing

-F: use the file name. please note that the file name should be followed immediately after f! Do not add parameters!

For example, the use of "tar-zcvfP tfile sfile" is incorrect. you must write it as "tar-zcvPf tfile sfile ".

-Z calls gzip to compress the archive file, and calls gzip to decompress the archive file when it is used with-x.

-Z calls compress to compress the archive file, and calls compress to decompress the archive file when it is connected to-x.

-J: does it have bzip2 attributes at the same time? That is, do I need to use bzip2 for compression?

-P: use the original attributes of the original file (the attributes will not be changed based on the user)

-P: absolute paths can be used for compression!

-N: a new date (yyyy/mm/dd) will be packed into the new file!

-- Exclude FILE: Do not pack the FILE during compression!

-T: view the files in the tarfile!

 

For example:

1.compress all. txt files under the current directory and archive them to the this.tar.gz file. we can use

Tar czvf this.tar.gz./*. txt

2.decompress the files in this.tar.gz under the current directory to the current directory.

Tar xzvf this.tar.gz

3. check which of the above this.tar.gz files are available?

Tar-ztvf this.tar.gz

4. under/tmp, I only want to unbind the etc/passwd in/tmp/etc.tar.gz.

Tar-zxvf/tmp/etc.tar.gz etc/passwd

5. back up all files in/etc/and save their permissions! This-p attribute is very important.

Tar-zxvpf/tmp/etc.tar.gz/etc

6. only new files in/home are backed up.

Tar-N "2005/06/01"-zcvf home.tar.gz/home

7. I want to back up/home,/etc, but not/home/dmtsai

Tar -- exclude/home/dmtsai-zcvf myfile.tar.gz/home/*/etc
