linux 解压缩

 

file.tar.gz和file.tar.bz2格式的解包命令如下； 
[root@localhost  ]# tar jxvf file.tar.bz2 
[root@localhost  ]# tar zxvf file.tar.gz

 

解压文件tgz
例如文件名为: yyyy.tgz
先使用GZIP解压为TAR文件
gzip -dv yyyy.tgz
同时解压后生成yyyy.tar文件
再使用tar解压yyyy.tar文件
tar xvf yyyy.tar
解压下边的命令：
gzip -dv R220-ESiVision-WebEnv-X86-Linux.tgz
tar xvf R220-ESiVision-WebEnv-X86-Linux.tar

压缩：tgz文件。
tar -czvf R220-ESiVision-WebEnv-X86-Linux.tgz apache-tomcat-5.5.23   jdk1.5.0_12 net-snmp-5.1.1
tar -czvf filename.tgz file 

把/home/kankan/shopstyleTest/code/data/feed/nuan_jp/下nuan_jp.xml和所有图片都打包成tgz：
tar -czvf nuan_jp.tgz /home/kankan/shopstyleTest/code/data/feed/nuan_jp/*
