centos 设置回收站

linux下没有回收站机制，rm删除可能会造成不可逆转的文件丢失，一下是两个简单脚本命令实现回收站效果。

vim /bin/delete    #创建删除命令

#!/bin/sh
realrm="/bin/rm"
if [ ! -d /tmp/trash ]
then
    mkdir -v /tmp/trash
    chmod 777 /tmp/trash
fi
if [ $# -eq 0 ]

then

echo "Usage: delete file1 [file2 file3....]"

echo "If the options contain -f, then the script will exec 'rm' directly"

fi
while getopts "dfiPRrvw" opt

do

case $opt in

f)

exec realrm "@"

;;

*)

# do nothing

;;

esac

done
echo -ne "Are you sure you want to move the files to the trash?[Y/N]:\a"

read reply

if [ reply = "y" -o reply = "Y" ]

then #####
for file in $@

do

if [ -f "file" -o -d "file" ]

then

if [ -f "file" ] && [ `ls -l file|awk ' {print $5}'-gt 2147483648 ] then echo -ne "$(pwd)/$file size is larger than 2G, will be deleted directly, Are you sure you want to remove it?[Y/N]:\a" read choice until [ $choice == y -o $choice == n ]; do read -p "wrong choice, try again!" choice done if [ $choice == n ] then echo "the operation is abort!" else "removing the $file" rm -rf $file fi elif [ -d "$file" ] && [ du -sb $file|awk '{print $1}'-gt 2147483648] then echo -ne "The directory:$(pwd)/$file is larger than 2G, will be deleted directly, Are you sure you want to remove it?[Y/N]:\a" read choice2 until [ $choice2 == y -o $choice2 == n ]; do read -p "wrong choice, try again!" choice done if [ $choice == n ] then echo "the operation is abort!" else "removing the $file" rm -rf $file  fi fi  fi done fi now= date +%Y%m%d_%H_%M_%S`

filename="${file##*/}"

newfilename="{file##*/}_{now}"

mark1="."

mark2="/"

if [ "file" = {file/$mark2} ]

then

fullpath="(pwd)/file"

elif [ "file" != {file/$mark1} ]

then

fullpath="(pwd){file/$mark1}"

else

fullpath="$file"

fi
echo "the full path of this file is : $fullpath"

if mv -f file /tmp/trash/newfilename

then

(/bin/logTrashDir "newfilename filename now $fullpath")

echo "files: $file is deleted"

else

echo "the operation is failed"

fi

该脚本会创建/tmp/trash文件夹用于存储垃圾文件，大于2G的文件会提示是否直接删除，使用delete -f 可直接将文件删除而不用移到回收站。

以下两个脚本可以配合delete命令执行操作。

vim /bin/cleanTrashCan       ###清理回收站命令

#!/bin/bash
arrayA=($(find /tmp/trash/* -mtime +7 | awk '{print $1}'))
    for file in ${arrayA[@]}
    do
        $(rm -rf "${file}")
        filename="${file##*/}"
        echo $filename
        $(sed -i /$filename/'d' "/tmp/trash/.log")
    done

执行上面的脚本会删除回收站内7天前的文件和文件夹

vim /bin/LogTrashDir        ###回收站日志脚本

#!/bin/sh
if [ ! -f /tmp/trash/.log ]
then
	touch /tmp/trash/.log
	chmod 700 /tmp/trash/.log
fi
	echo $1 $2 $3 $4 >> /tmp/trash/.log
