rmtrash 是linux和mac下命令行版本rm的回收站，安装后对用户透明，符合正常使用rm的习惯(支持rm -fr file哦)，有了他再也不怕rm时候手颤抖了(能自动拒绝 rm -fr / 哦)。
rmtrash stands for "rm trash" which acts just like the system built-in rm command,and just moves the file to the trash for recovery when needed.
1、使用说明
（1）安装
wget --no-check-certificate https://raw.githubusercontent.com/LaiJingli/rmtrash/master/rmtrash.sh
mv rmtrash.sh /bin/
chmod +x /bin/rmtrash.sha、如果仅对单个用户启用回收站，只需第一次执行如下命令即可：
/bin/rmtrash.shb、如果想对全局所有用户启用回收站，需要修改bashrc全局配置文件后即可：
echo "alias rm=/bin/rmtrash.sh" >>/etc/bashrc（2）使用
rm -h
Usage1: rmtrash.sh file1 [file2] [dir3] [....] delete the files or dirs,and mv them to the rmtrash recycle bin
Usage2: rm file1 [file2] [dir3] [....] delete the files or dirs,and mv them to the rmtrash recycle bin
rm is alias to rmtrash.sh.
options:
-f mv one or more files to the rmtrash recycle bin
-r mv one or more files to the rmtrash recycle bin
-fr mv one or more files to the rmtrash recycle bin
-rf mv one or more files to the rmtrash recycle bin
-R Restore selected files to the originalpath from rmtrash recycle bin
-l list the contens of rmtrash recycle bin
-i show detailed log of the deleted file history
-d delete one or more files by user's input file name from the trash
-e empty the rmtrash recycle bin
-h display this help menu如果有问题，执行以下2条命令排查,或者退出重新登录系统
source ~/.bashrc
alias |grep rm（3）如果需要彻底删除文件
a、# rm -e 清空回收站
b、# /bin/rm file 直接删除文件而不经过回收站2、适用系统linux、Mac osx。
#!/bin/bash

###trash目录define
realrm="/bin/rm"
trash_dir=~/.rmtrash/
trash_log=~/.rmtrash.log
###判断trash目录是否存在，不存在则创建
if [ ! -d $trash_dir ] ;then
mkdir -v $trash_dir
fi
###动态修改用户shell中的alias配置
os_type=`uname`
shell_path=$SHELL
shell_type=`echo $SHELL|awk -F/ '{print $NF}'`
alias_file=~/.${shell_type}rc
alias_rm=`cat $alias_file|grep ^"alias rm="`
return_value=$?
#echo return_value: $return_value
#echo alias_rm: $alias_rm
###如果不存在rm alias，则生成
if [[ $return_value -ne 0 ]] ;then
echo first time to run rmtrash
echo "alias rm=/bin/rmtrash.sh" >>$alias_file && source $alias_file
###如果存在rm alias，且不是指向rmtrash的，则注释掉，区分linux 和mac
elif [[ "$alias_rm" != "alias rm=/bin/rmtrash.sh" ]];then
echo already has alias rm,and must commit out
if [[ $os_type == Darwin ]];then
sed -i .bak 's/^alias\ rm=/#alias\ rm=/g' $alias_file && \
echo "alias rm=/bin/rmtrash.sh" >>$alias_file && \
source $alias_file
elif [[ $os_type == Linux ]];then
sed -i.bak 's/^alias\ rm=/#alias\ rm=/g' $alias_file && \
echo "alias rm=/bin/rmtrash.sh" >>$alias_file && \
source $alias_file

###rm restore function
rm_restore () {
echo ----------------------------

###判断原始位置的是否有同名文件存在
originalpath=`cat $trash_log|grep /$file$|awk '{print $5}'`
if [[ `ls $originalpath` ]];then

###linux和mac下sed的用法有细微差别，故需通过操作系统类型进行选择对应的sed格式

### rm show delete log function
rm_infolog () {
echo ----------------------------
echo detailed deleted file log:
cat $trash_log
}
###rm empty trash function

}
###清空回收站中30天之前执行rm删除过的文件
rm_delete_by_30_days () {
rm_mv_30_days_ago_timestamp=$1
###30*24*3600=2592000
#30_days_by_seconds=2592000
#cat $trash_log|awk 'BEGIN{30_days_by_seconds=2592000}{if()}'
awk 'END{
print 时间差:$2-2592000
{if ($2-2592000>100) print dayu}
}
' $trash_log
}
###跨分区的问题
#####主程序开始
###参数个数为0，输出help
if [ $# -eq 0 ] ;then rm_usage ;fi
###根据用户输入选项执行相应动作
###通过非显示的方式(加入fr选项，但在case里不做匹配操作，遇到含-fr/-rf/-f/-r时直接删除)支持很多用户的使用习惯rm -fr file,rm -rf file
while getopts lRiecdhfr option ;do
case "$option" in
l) rm_list;;
R) rm_list
rm_restore;;
i) rm_infolog;;
h) rm_usage;;
e) rm_empty;;
c) rm_delete_by_30_days;;
d) rm_list
rm_delete;;
\?)rm_usage
exit 1;;
esac
done
shift $((OPTIND-1))
###将文件名的参数依次传递给rm_mv函数
while [ $# -ne 0 ];do
file=$1
echo file=$file
rm_mv
shift
done
