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 //Extract rar

unzip file.zip //Extract zip

2. Decompress *.gz with gzip -d or gunzip

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 to decompress

6. *.Z Use uncompress to decompress

7, *.tar.Z Use tar -xZf to decompress
