# Bash版回收站 经常看到网上有人说把一个重要的文件删除了，而恢复成本很高，所以一直在想Linux终端中为什么没有像Windows下的回收站这样的设计，直到看到Unix编程艺术上的一段解释。 其实，Linux世袭了Unix的设计理念与传统，而Unix本身并没有这样的设计并延续到了Linux。 Unix面向更加专业的用户 ,Unix的开发者喜欢清晰、简单的操作，用户告诉做什么就做什么，即便用户使用的命令等价于“向我开枪”的命令。而这样做Unix的开发本能辩解的就是：保护用户避免自我损害，应该是GUI或应用程序级别的事，而非操作系统:)。 这就解释了Linux终端为什么没有类似Windows回收站的设计，当然我们也可以通过Shell方式自己来实现一个类似回收站的功能，以下是笔者在2007年与2008年时写的Shell回收站，供参考： 1.第一版本（http://bbs.chinaunix.net/thread-1034672-1-1.html） 2. 第二版本http://m.blog.chinaunix.net/uid-7176662-id-2068124.html） ``` #!/bin/bash #----------------------------------------------------------------- # filename: # author: wds # begin:2008.1.27 # end:2008.2.1 # version: v.2 # script address: http://blog.chinaunix.net/u1/40306/index.html #----------------------------------------------------------------- from1=$1 from2=$2 garbage=$HOME/.garbage mvlog=$garbage/mv.log if [ ! -e $garbage ] then mkdir -p $garbage chmod 777 $garbage fi function rand { a=(0 1 2 3 4 5 6 7 8 9 a b c d e A B C D E F ) for ((i=0;i<7;i++));do echo -n ${a[$RANDOM % ${#a[*]}]} done } random=$(rand) function rm1 { if [ -d "$from1" ] then echo "rm: cannot remove '$from1/' : Is a directory" else echo "`pwd`/:$from1:$random:`date`" >> $mvlog mv "$from1" "$garbage/$from1:$random" fi } function more { for file in * do echo "`pwd`/:$file:$random:`date`" >> $mvlog mv $file "$garbage/$file:$random" done 2> /dev/null } function rmi { if [ ! -d "$from2" ] then echo -n "rm:remove regular empty file '$from2'?" ; read answer; if [ "$answer" = 'y' -o "$answer" = 'Y' ] then echo "`pwd`/:$from2:$random:`date`" >> $mvlog mv "$from2" "$garbage/$from2:$random" fi else echo "rm: cannot remove directory '$from2': Is a directory" fi } function rmf { if [ ! -d "$from2" ] then echo "`pwd`/:$from2:$random:`date`" >> $mvlog mv "$from2" "$garbage/$from2:$random" else echo "rm: cannot remove directory '$from2': Is a directory" fi } function rmr { if [ -e "$from2" ] then result=$(echo $from2 | sed 's/\///g') echo "`pwd`/:$result:$random:`date`" >> $mvlog mv "$result" "$garbage/$result:$random" fi } function rml { while : do clear line=$(cat -n $mvlog | awk -F : '{print $1,"FileName:"$2, "Time:"$4}') linecount=$(cat $mvlog | wc -l) echo -e "$line\c" echo echo echo "Please input number you want revent(line count:$linecount)--exit(e)" read answer if [ "$answer" = e -o "$answer" = E ] then break else ( echo "please input y(sure:)" read answer1 if [ "$answer1" = y -o "$answer" = Y ] then address=$(sed -n "$answer""p" $mvlog | awk -F : '{print $1}') filename=$(sed -n "$answer""p" $mvlog | awk -F : '{print $2}') filerand=$(sed -n "$answer""p" $mvlog | awk -F : '{print $3}') fullname=$address$filename if [ -e "$fullname" ] then echo "The file exist!" sleep 1 else old="$garbage/$filename:$filerand" new="$address$filename" mv "$old" "$new" delline=$( cat $mvlog | sed "$answer""d" | sort -o $mvlog) echo "update ok!!!" sleep 1 fi fi ) fi done } function help { echo " -i) If you wants delete some file , this function is confirm you want,the same as old rm. -f) If you wants delete some directory ,you can use this function ,the same as old rm. -r) If you wants delete some directory of file ,this function can use , the same as old rm. -l) This is new function,is you wants resume some file or directory you can use this function, first this function can list some file in you garbage , these have some number ,if you wants resume 1,you can input 1 and then input y to confirm.
