Detailed explanation of tar decompression command

Compress the directory and its files today:
/usr/local/test

# tar -cvf /usr/local/auto_bak/test.tar /usr/local/test Only packaging, not compression
# tar -zcvf / After usr/local/auto_bak/test.tar.gz /usr/local/test is packaged, the name of the compressed file after the parameter f is compressed by gzip. It is customary to use tar to do it. If the z parameter is added, it is tar.gz or tgz represents a gzip-compressed tar file

Decompression operation:
#tar -zxvf /usr/local/test.tar.gz

compression

tar –cvf jpg.tar *.jpg //Package all jpg files in the directory into tar.jpg

tar –czf jpg.tar.gz *.jpg //Package all jpg files in the directory into jpg.tar, and compress them with gzip to generate a gzip-compressed package named jpg.tar.gz

tar –cjf jpg.tar. bz2 *.jpg //Package all jpg files in the directory into jpg.tar, and compress them with bzip2 to generate a bzip2-compressed package named jpg.tar.bz2

tar –cZf jpg.tar. Z *.jpg //Package all jpg files in the directory into jpg.tar, and compress them with compress to generate a umcompress compressed package, named jpg.tar.Z

rar a jpg.rar *. jpg //For compression in rar format, you need to download rar for linux first

zip jpg.zip *.jpg //For compression in zip format, you need to download zip for linux first

Unzip

tar –xvf file.tar //Unzip tar package

tar -xzvf file.tar.gz //Extract tar.gz

tar -xjvf file.tar.bz2 //Extract tar.bz2

tar –xZvf file.tar.Z //Extract tar.Z

unrar e file.rar //Unzip rar

unzip file.zip //Unzip zip

(1), *.tar Use tar –xvf to decompress
(2), *.gz Use gzip -d or Gunzip decompress
(3), *.tar.gz and *.tgz use tar –xzf to decompress
(4), *.bz2 use bzip2 -d or bunzip2 to decompress
(5), *.tar.bz2 use tar – xjf Decompress
(6), *.Z use uncompress to decompress
(7), *.tar.Z use tar –xZf to decompress
(8), *.rar use unrar e to decompress
