使用shell腳本實現USB設備的加載與文件復制

在Linux操作系統中，如果插入一個USB設備，需要用mount掛載命令才能實現這個設備的加載，下面寫一個USB設備掛載與文件復制的Shell程序，程序需求：

1、運行時，提示用戶輸入“y”或者“Y”，確定是否掛載USB設備，U盤文件/dev/sdc1 

1. if[$ANS="Y" -o $ANS = "y"]
2. then mount -t vfat /dev/sdc1 /mnt/usb

2、確定是否復制文件到/root
最好用$?判斷一下是否復制成功，$? -eq 0，表示復制成功

1. while[$ANS="Y" -o $ANS = "y"]
2. do
3. ls -lha /mnt/usb
4. echo "type the filename you want to copy"
5. read FILE
6. cp /mnt/usb/"$FILE" /root

3、確定是否復制文件到USB設備中

1. echo "Do you want to copy files to USB(y/n)"
2. read ANS
3. while[$ANS="Y" -o $ANS = "y"]
4. do
5. ls -lh /root
6. echo "type the filename you want to copy"
7. read FILE
8. cp /root/"$FILE" /mnt/usb
9. if[ $? -eq 0];then
10. echo "Finished"
11. else
12. echo "Error"
13. fi
14. echo "any other files(Y/N)"
15. read ANS
16. done

完整的腳本：

1. #!/bin/bash
2. #autousb
4. echo "Welcome to USB"
5. echo "Do you want load USB(Y/N)"
6. read ANS
8. if[$ANS="Y" -o $ANS = "y"];
9. then mount -t vfat /dev/sdc1 /mnt/usb
10. echo "Do you want to copy files to /root(y/n)?"
11. read ANS
12. while[$ANS="Y" -o $ANS = "y"]
13. do
14. ls -lha /mnt/usb
15. echo "type the filename you want to copy"
16. read FILE
17. cp /mnt/usb/"$FILE" /root
18. if[ $? -eq 0];then
19. echo "Finished"
20. else
21. echo "Error"
22. fi
23. echo "any other files(Y/N)"
24. read ANS
25. done
26. fi
28. echo "Do you want to copy files to USB(y/n)"
29. read ANS
30. while[$ANS="Y" -o $ANS = "y"]
31. do
32. ls -lh /root
33. echo "type the filename you want to copy"
34. read FILE
35. cp /root/"$FILE" /mnt/usb
36. if[ $? -eq 0];then
37. echo "Finished"
38. else
39. echo "Error"
40. fi
41. echo "any other files(Y/N)"
42. read ANS
43. done
45. echo "Do you want to umount?(y/n)"
46. read ANS
49. if[$ANS="Y" -o $ANS = "y"];then
50. umount /mnt/usb
51. else
52. echo "umount error"
53. fi
54. echo "GoodBye!!"
