给rm命令加上回收站功能

背景：
在群里，总会有人聊到曾经做过的最坑的事情，其中当然少不了rm命令，比如最出名的rm -rf /*命令。
受HDFS回收站机制的启发，我即兴的写了一个shell脚本来实现类似的功能。

具体配置：
[dong@localhost ~]$ sudo touch /usr/bin/delete
[dong@localhost ~]$ sudo chmod +x /usr/bin/delete
[dong@localhost ~]$ sudo vim /usr/bin/delete

#!/bin/bash

trash_dir=${HOME}/.Trash/$(date +%Y%m%d%H%M%S)

function move_item(){

item=$1

full_path=$2

full_dir=$(dirname ${full_path})

mkdir -p ${trash_dir}${full_dir}

mv ${item} ${trash_dir}${full_path}

if [[ $? -eq 0 ]]; then

echo "Moved ${item} to ${trash_dir}${full_path}"

}

if [[ $# -eq 0 ]] || $(echo "$1" |grep -Ewq '\-h|\-\-help'); then

echo "${0} [-f] [*|FILE]"

exit 2

for item in $@; do

if $(echo ${item} |grep -vq '^-'); then

if $(echo ${item} |grep -q '^/'); then

full_path=${item}

else

full_path=$(pwd)/${item}

if $(echo $@ |grep -Ewq '\-f|\-rf|\-fr'); then

move_item ${item} ${full_path}

else

echo -n "Move ${item} to ${trash_dir}${full_path}? [y/n] "

read yorn

if $(echo ${yorn} |grep -Ewq 'y|Y|yes|YES'); then

move_item ${item} ${full_path}

done

[dong@localhost ~]$ mkdir tmp
[dong@localhost ~]$ cd tmp
[dong@localhost tmp]$ mkdir 1 2 3
[dong@localhost tmp]$ echo 1 > 1/1.txt
[dong@localhost tmp]$ echo 2 > 2/2.txt
[dong@localhost tmp]$ echo 3 > 3/3.txt
[dong@localhost tmp]$ touch a b c
[dong@localhost tmp]$ ln -s a d
[dong@localhost tmp]$ delete 1

Move 1 to /home/dong/.Trash/20160415114210/home/dong/tmp/1? [y/n] y
Moved 1 to /home/dong/.Trash/20160415114210/home/dong/tmp/1

[dong@localhost tmp]$ delete -f *

Moved 2 to /home/dong/.Trash/20160415114217/home/dong/tmp/2
Moved 3 to /home/dong/.Trash/20160415114217/home/dong/tmp/3
Moved a to /home/dong/.Trash/20160415114217/home/dong/tmp/a
Moved b to /home/dong/.Trash/20160415114217/home/dong/tmp/b
Moved c to /home/dong/.Trash/20160415114217/home/dong/tmp/c
Moved d to /home/dong/.Trash/20160415114217/home/dong/tmp/d
