用mv替换rm

慎用rm命令！
第一种：
[root@localhost ~]# vi .bashrc

mkdir -p ~/.trash                                    #加到文件尾
alias rm=trash
alias r=trash
alias rl='ls ~/.trash'
alias ur=undelfile
undelfile(){
    mv -i ~/.trash/$@ ./
}
trash(){
    mv $@ ~/.trash/
}

[root@localhost ~]# source ~/.bashrc                          #生效

第二种：
[root@localhost ~]# echo "alias del='source ~/script/del'" >> ~/.bashrc
[root@localhost ~]# vi ~/script/del                           #脚本路径

#!/bin/bash                                           #脚本内容

TRASH=~/.trash             # TRASH是自己建立的用来存放删除文件的临时文件夹

if [ "$1" =  "" ]
then
echo "Usage: del F (F is the argument of the target files or directories you want to delete)"
else
echo "$1 is moved to temporary trash in ~/.trash"
mv $1 $TRASH --backup=numbered -fi      #移动被删除文件至临时文件夹，如同名，则自动编号备份
fi

[root@localhost ~]# source ~/.bashrc
