Linux命令行压缩 & 解压缩 - tar

tar 为 GNU 打包工具,目前在标准 Linux 发行版上已经整合进压缩/解压缩工具 gzip、bzip2 和 xz。

  • 打包,后缀为 .tar,称为 tarfile
  • 打包 + 压缩,后缀为 .tar.gz.tar.bz2.tar.xz,称为 tarball。此为 linux 最常用的压缩、解压缩方式。

windows 中常见的压缩包有 .zip.rar,可通过 unzipunrar 两个工具进行解压。通过 apt-get install 安装即可。

  • 压缩
    • gzip,tar -zcvf xxx.tar.gz ./*
    • bzip2,tar -jcvf xxx.tar.bz2 ./*
    • xz,tar -Jcvf xxx.tar.xz ./*
  • 解压缩,tar -xvf xxx.tar.gz
  • 查看压缩包内容,tar -tf xxx.tar.gz

p4factory 为例,log 如下。
