mv,Directory not empty不能目录覆盖

    一。
    

    mv  /test1/* /test2/test1
    

    rm -rf /test1
    

    

    二。
    

    

    You can however use 
    
      rsync
    
     with the 
    
      --remove-source-files
    
     option (and possibly others) to merge one directory into another.


  

_{rsync won't delete any directories, so you will have to do something like find -type d -empty -delete afterwards to get rid of the empty source directory tree.}

  

     
  
  
    
      rsync -av /source/ /destination/

(after checking)

rm -rf /source/
      

      

      

      
        
          --remove-source-files
        
         has the advantage of only removing files that were transferred successfully, 
        

        so you can use 
        
          find
        
         to remove empty directories and will be left with everything that wasn't transferred without having to check 
        
          rsync
        
        s output
        

        

      
    
  
  
    
      cd source; find -type f | xargs -n 1 -I {} mv {} dest/{}


    
  
  
    
      
        

        

        三。
        

      
    
  
  

    

      I'd recommend these four steps:
    
    
      
        cd ${SOURCE}; 

find . -type d -exec mkdir -p ${DEST}/\{} \; 

find . -type f -exec mv \{} ${DEST}/\{} \; 

find . -type d -empty -delete


      
    
    

      or better yet, here's a script that implements semantics similar to 
      
        mv
      
      :
    
    
      
        #!/bin/bash



DEST=${@:${#@}}; for SRC in ${@:1:$(({#@} -1))}; do   (

    cd $SRC;

    find . -type d -exec mkdir -p ${DEST}/\{} \; 

    find . -type f -exec mv \{} ${DEST}/\{} \; 

    find . -type d -empty -delete

) done


      
    
  
  
    
      
        

        

      
    
  
  

    

      

        

          

            
              0 
              
                down vote
              
            
          
        
        

          

            

              Here is a script that worked for me. I prefer mv over rsync, so I use Jewel and Jonathan Mayer's solutions.
            
            
              
                #!/bin/bash



# usage source1 .. sourceN dest



length=$(($#-1))

sources=${@:1:$length}

DEST=$(readlink -f ${!#})

for SRC in $sources; do

    pushd $SRC;

    find . -type d -exec mkdir -p ${DEST}/{} \;

    find . -type f -exec mv {} ${DEST}/{} \;

    find . -type d -empty -delete

    popd
              
            
          
        
      
    
  
  
    
      
        

        

        

        if you use use 
        
          mv --backup=numbered
        
        

         (or one of the other options for the --backup switch),
        

         then 
        
          mv
        
         will complete the merge and preserve the files intended to be overwritten
