如何压缩多个文件？

syntax: zip {.zip 要压缩的文件名} {被压缩的文件名}

# zip var-log-files.zip /var/log/* 
  adding: var/log/acpid (deflated 81%)

  adding: var/log/anaconda.syslog (deflated 73%) 
  adding: var/log/anaconda.xlog (deflated 82%) 
  adding: var/log/audit/ (stored 0%) 
  adding: var/log/boot.log (stored 0%) 
  adding: var/log/boot.log.1 (deflated 40%) 
  adding: var/log/boot.log.2 (deflated 42%) 
  adding: var/log/boot.log.3 (deflated 40%) 
  adding: var/log/boot.log.4 (deflated 40%)

如何压缩一个目录及其下的文件?

# zip -r var-log-dir.zip /var/log/

如何解压缩*.zip文件

# unzip var-log.zip 
Archive:  var-log.zip 
  inflating: var/log/acpid 
  inflating: var/log/anaconda.log 
  inflating: var/log/anaconda.syslog 
  inflating: var/log/anaconda.xlog 
   creating: var/log/audit/

给unzip加上一个-v参数可以输出详细的解压缩过程

# unzip -v var-log.zip 
 
Archive:  var-log.zip
