功能：如题

 

代码：

　　

#!/bin/sh

recursive( )
{
     for file in $1
     do
       subfile=`ls $2$3/$file`
       for subsubfile in $subfile
       do
 #               echo $subsubfile
         if [ "$subsubfile" == "$2$3/$file" ]
         then
                rm -rf $3/$file
                mv $subsubfile $3/$file
         else
                recursive `ls $2$3/$file` $2 $3/$file;
         fi
       done
     done
}

cd /tmp
mkdir update;
tar -zxvf update.tgz -C update;
chmod -R 755 /tmp/update/*;

rootdir="/tmp/update"






filelist=`ls /tmp/update/`
for file in $filelist
do
 subfile=`ls $rootdir/$file`

  for subsubfile in $subfile
   do
   if [ "$subsubfile" != "$rootdir/$file" ]
   then
        $(recursive `ls $rootdir/$file` $rootdir /$file)
        # rm -rf /$file/$subfile
        # mv $rootdir/$file/$subsubfile /$file
        break 1;

   else
        kill -9 `ps|grep $file`
        rm -f /usr/bin/$file
        mv $rootdir/$file /usr/bin
