讨论一下：mount 时会不会提示本地目录已经mount了一个了？

零二年的夏天

那为什么不多建一个目录呢？

试试这个脚本。

1. 
   
2. #!/bin/bash
   
3. #
   
4. #Name : MyMount
   
5. #Author : PopZslam
   
6. #Descript : To avoid mount a device twice or more
   
7. #
   
8. #---------------
   
9. _MOUNTTABLENOPATH=`mount|awk -F"/" '{ print $3; }'`
   
10. _MOUNTTABLED=`mount|awk '{ print $3"/"; }'`
    
11. 
    
12. # Check if the device is used or not.
    
13. # If you needn't the path
    
14. echo "$_MOUNTTABLENOPATH"|grep $1 1>;/dev/null
    
15.         if [ $? -eq 0 ] ; then
    
16.         printf "\n\tThe device that you want mount is USED !\n\n"
    
17.         exit 0
    
18.         fi
    
19. # Check if the directory is used or not.This situation will effect
    
20. # when you want to mount a floppy disk or a CD device.
    
21. echo $_MOUNTTABLED|grep $1 1>;/dev/null
    
22. if [ $? -eq 0 ] ; then
    
23.         printf "\n\tThe directory that you want mount is USED !\n\n"
    
24.         exit 0
    
25. fi
    
26. # Check if the directory is used or not.
    
27. echo $2|grep "mnt" 1>;/dev/null
    
28. if [ $? -eq 0 ] ; then
    
29.         echo $_MOUNTTABLED|grep $2 1>;/dev/null
    
30.         if [ $? -eq 0 ] ; then
    
31.         printf "\n\tThe directory that you want mount is USED !\n\n"
    
32.         exit 0
    
33.         fi
    
34. fi
    
35. 
    
36. # Exec the command
    
37. mount $1 $2
    
38. 
    
39. #------------------
    
40. #End

想再简化些，可是不会了。
