写了两天，终于写完了，基本可实现如win下的“回收站”功能。
del: 删除东西用的。
del {路径}
路径允许通配符，允许多个路径，允许相对与绝对路径混用
lstrash: 看自己的垃圾筒内有什么。当然，一如“回收站”，如果你自己硬塞进去
的东西它是记录不了的。
lstrash [-n]
显示垃圾筒里的东西，参数-n用于显示其在记录文件中的行号。
undel: 恢复用。
undel {-ln LINENUMBER | -tn TRASHNAME | -sp SOURCEPATH}
-ln LINUENUMBER LINENUMBER为lstrash -n显示的行号
-tn TRASHNAME TRASHNAME，文件在垃圾筒内的名字，记录文件的第一列。
-sp SOURCEPATH SOURCEPATH，删除前的原文件的绝对路径--能力有限，不能确定唯一的绝对跟径……--也就是记录文件的第二加第三列形成的路径。

You should copy /KNOPPIX/*, not / !

[原创]:安全删除和恢复文件的脚本
http://www.chinaunix.net 作者:bjgirl 发表于：2003-12-22 14:30:34

由于现在的linux文件系统大多是etx3的,一不小心删除后是无法恢复的(至少我不知道),而rm是个很危险的操作!鉴于此我写了这俩小脚本,希望GGJJ们指点!
1,用root修改rm的权限:
#chmod o-x /bin/rm
2,在用户主目录下创建个"垃圾箱"
$mkdir ~/.temp

删除文件脚本:

cat erase

#!/bin/ksh
(($#==0)) && { echo "No paraments!";exit 1; }
for i in $*
do
        mv -f $i ~/.temp/$(find $(pwd) -maxdepth 1 -name $i|tr "/" "=")
done

恢复文件脚本:

cat unerase

#!/bin/ksh
(($#==0))&&{ echo "No paraments!";exit 1; }
cd ~/.temp
list=$(for i in $*;do ls ~/.temp|grep "\<$i\>";done)
for j in $list
do
  file=$(echo $j|tr "=" "/")
  mv $j ${file%/*}/${file##*/}
done

算法：
1.先find /pathname -print >filea #获取两个文件夹里所有文件的全名。
2,比较文件，先删去要同步的文件夹里多余的文件。接着重新获得需要同步的文件夹里所有文件的全名。
3.比较文件，把源文件夹里增加的文件CP到要同步的文件夹中。
这个脚本是同步/share目录里的所有文件，需要备份到/mnt/d/share

#!/bin/bash
mount /dev/hda6 /mnt/d 2>/dev/null ; unalias rm cp
rm /share/c/app/*o /share/c/tmp/*o /share/c/app/*core /share/c/tmp/*core /share/c/app/a.out /share/c/tmp/a.out
 find /share -print >/tmp/.share_    #把/share的所有文件的全名保存到/tmp/.share_
 find /mnt/d/share -print |sed 's/\/mnt\/d//g' >/tmp/.d_
 chmod 700 /tmp/.share_ /tmp/.d_
 count=0
 for i in $(comm -23 /tmp/.d_ /tmp/.share_) ; do     #比较两个文件里/tmp.d_ 与/tmp./share_的不同。
 echo "/mnt/d$i"
 rm "/mnt/d$i" ; count=$((count+1))    #删除/mnt/d/share/*里的多余的文件和计数。
 done    #for command ;do command ; done的循环到此结束。
 echo "del $count file at /mnt/d/share/"
 find /mnt/d/share -print |sed 's/\/mnt\/d//g' >/tmp/.d_ ; count=0    #重新获得文件的全名。初始化计数器。
 for i in $(comm -23 /tmp/.share_ /tmp/.d_) ; do
 echo $i
 cp $i "/mnt/d$i" ; count=$((count+1))    #备份/share里新增加的文件到/mnt/d/share,同时计数。
 done
 echo "already copied $count file from /share to /mnt/d/share " ;sync
 umount /mnt/d 2>/dev/null
 echo done

# Program: /usr/sbin/adduser
# Purpose: Interactive front end to /usr/sbin/useradd for Slackware Linux
# Author:  Stuart Winter <stuart@polplex.co.uk>
#          based on the original Slackware adduser by Hrvoje Dogan
#          with modifications by Patrick Volkerding
# Version: 1.05
##########################################################################
# History #
###########
# v1.05 - 04/01/03
#       * Advise & prevent users from creating logins with '.' characters
#         in the user name.
#       * Made pending account creation info look neater
# v1.04 - 09/06/02
#       * Catered for shadow-4.0.3's 'useradd' binary that no longer
#         will let you create a user that has any uppercase chars in it
#         This was reported on the userlocal.org forums
#         by 'xcp' - thanks. <sw,pjv>
# v1.03 - 20/05/02
#       * Support 'broken' (null lines in) /etc/passwd and
#         /etc/group files <sw>
#       * For recycling UIDs (default still 'off'), we now look in
#         /etc/login.defs for the UID_MIN value and use it
#         If not found then default to 1000 <sw>
# v1.02 - 10/04/02
#       * Fix user-specified UID bug. <pjv>
# v1.01 - 23/03/02
#       * Match Slackware indenting style, simplify. <pjv>
