Shell把rm改造为mv操作(防止误删文件)

mkdir -p ~/.trash  
 >.bashrc
 cat>.bashrc<<EOF
 # for rm {{
 # mkdir ~/.delete, when rm somethings ,mv them to here
 if [ ! -d $HOME/.delete ]
 then
     mkdir $HOME/.delete
 fi
 unDoRm() {
   mv -i $HOME/.delete/$@ ./
 }
 toBackup()
 {
     for thing in $@
     do
         echo $thing | grep '^-' > /dev/null
         if [ ! $? = 0 ]
         then
             mv $thing $HOME/.delete
             echo mv $thing to ~/.delete, you can backup them
         fi
     done
 
 }
 cleanDelete()
 {
     echo 'clear backup files?[y/N]'
     read confirm
     [ $confirm = 'y' ] || [ $confirm = 'Y' ]  && /usr/bin/rm -rf $HOME/.delete/*
 }
