A auto explode script

写了个根据扩展名自动解压缩的脚本，作为这一阶段学习Bash的总结:

 

#! /bin/bash
# filename:autotar

 

PATH_DIR=`dirname $1`
BASE_NAME=`basename $1`
UN_RAR=/usr/bin/unrar

 

tar_fun(){
  case ${BASE_NAME##*.} in
      gz)
        tar zxvf $BASE_NAME
        ;;

      bz2)
        tar jxvf $BASE_NAME
        ;;
      tgz)

        tar zxvf $BASE_NAME

        ;;

      tar)

        tar xvf $BASE_NAME

        ;;

      zip)
        unzip $BASE_NAME
        ;;
      rar)
        $UN_RAR x $1
        ;;
  esac
}

 

cd $PATH_DIR
tar_fun
cd -

 

exit 0
